Data was deleted on April 9 as the SSR fill level was very high. This move brought the SSR fill level down from 94% to around 56% full. We skipped over data recorded from 2018-03-30 to 2018-04-01 ~11:30 UTC.<br />

Regarding the lock less experiment, it was concluded that a spin-down would not make the situation dramatically better. After getting temperature readings, the spin rate should be brought back to 15 RPM. Then, another anneal will be performed. <br />

The Sun was active this week, producing seven M-class flares. Currently there are five AR on disk, but four of them are expected to rotate off the disk very soon.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 39 30 7 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 21 17 5 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 12 11 2 0<br />
<br />
There were RHESSI flares/GOES flares 188 / 76<br />
over the time range 28-Mar-17 04-Apr-17<br />
<br />
<br />
== Memory Management ==<br />
<br />
Early the week, the SSR was at 0% at the end of each day's contacts. In response to the high solar activities and the turn-on of some detectors, the SSR reached 80% and the decimation was switched to active/vigorous from normal/vigorous.<br />
<br />
== Spacecraft Status ==<br />
<br />
Detectors 3 and 6 are recording events. Due to the increased solar activities, D1, 5 and 8 were turned on. D5 was turned off after ~24 hours due to its unexpectedly high event rate.<br />
<br />
The cold tips are 129.5 and 128.0 K as of 5-Apr-2017. The cold plates, 1 and 2 are 153.3 and 151.8 K. Cryocooler power is steady at 76W. <br />

== Detector issues ==<br />
<br />
Detectors 1, 3, 6 and 8 are powered on, and are recording events. While the AR2644 that produced M-class flares is now at the limb, there is still another big AR on disk. So it was determined to keep the detectors 1 and 8 on unless there is an issue with the temperatures. <br />
<br />
<br />
== Notes ==<br />
<br />
For the flare of April 3 14UT, pileup was relatively high (40% at 30 keV) with the attenuator state A1. It was decided to revisit the current thresholds of the thin/thick attenuator logic.<br />

== Solar Activity ==<br />
<br />
The Sun was active this week, producing seven M-class flares. Currently there are five AR on disk, but four of them are expected to rotate off the disk very soon.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 39 30 7 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 21 17 5 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 12 11 2 0<br />
<br />
There were RHESSI flares/GOES flares 188 / 76<br />
over the time range 28-Mar-17 04-Apr-17<br />
<br />
<br />
== Memory Management ==<br />
<br />
Early the week, the SSR was at 0% at the end of each day's contacts. In response to the high solar activities and the turn-on of some detectors, the SSR reached 80% and the decimation was switched to active/vigorous from normal/vigorous.<br />
<br />
== Spacecraft Status ==<br />
<br />
Detectors 3 and 6 are recording events. Due to the increased solar activities, D1, 5 and 8 were turned on. D5 was turned off after ~24 hours due to its unexpectedly high event rate.<br />
<br />
The cold tips are 129.5 and 128.0 K as of 5-Apr-2017. The cold plates, 1 and 2 are 153.3 and 151.8 K. Cryocooler power is steady at 76W. <br />

== Data Gaps ==<br />
<br />
Relatively large (>300 sec) data gaps as follows:<br />

<div>This page contains information about changes/issues for RHESSI detector 5 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 5 anneal 2012]]<br />
<br />
===Notes===<br />
<br />
* After the 2014 anneal, detector 5 is UNSEGMENTED.<br />
<br />
* A tweak shortly after the anneal was completed:<br />
G5 front slow to 0x80 (was 0x70) on 2014 Aug. 14 after 03:40 UTC<br />
<br />
* In late December 2014 some weak signal of segmentation were seen on G5. On January 5, 2015 at 14:57 UTC we set new values for the front fast and front slow thresholds on this detector. We need to keep an eye on its behaviour. Detector 5 is now weakly SEGMENTED.<br />
<br />
G5 front slow to 0x0C (was 0x80) on 2015 Jan. 5 after 14:57 UTC<br />
G5 front fast to 0x2E (was 0x60) on 2015 Jan. 5 after 14:57 UTC<br />
<br />
* On 2014 Jan 8, the rear fast threshold was raised since fast counts were eating up a lot of livetime.<br />
<br />
15-008-17:44:15 /IDPULOAD VALUE=0x50 ;(was 0x45)<br />
<br />
* On 2015 May 26 starting at 19:15:09 we increased the rear fast threshold by 0x08<br />
<br />
2015-146-19:15:09 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-146-19:15:21 /IDPLOAD VALUE=0x58 ; was 0x50<br />
<br />
* Aug. 24, 2015: The rear fast threshold was raised, successfully bringing the livetime up to >75%.<br />
2015-236-20:46:37 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-236-20:46:59 /IDPLOAD VALUE=0x70 ; was 0x58<br />
<br />
* On October 8, the front fast threshold was raised to try and raise livetime. Prior to these changes, D5 front livetime was at ~30%. As the changes were made on a BGS pass, the D5 front fast rates fell from 131k to 2100, and the livetimes rose accordingly, so the changes were successful. <br />
<br />
2015-281-21:49:25 /IDPUTABLE5 OFFSET=FRONTFASTDAC<br />
2015-281-21:49:37 /IDPLOAD VALUE=0x40 ; was 0x2E<br />
<br />
* The rear fast threshold was also raised on Oct. 9, for the usual reason. This worked, bringing the livetime up to >80%, though it's slowly dropped in the days since and might need another boost soon.<br />
<br />
2015-282-23:02:49 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-282-23:02:58 /IDPLOAD VALUE=0x90 ; was 0x80<br />
<br />
* November 23, 2015, front fast threshold raised due to a rapid decrease of the livetime.<br />
<br />
2015-327-22:11:03 /IDPUTABLE5 OFFSET=FRONTFASTDAC <br />
2015-327-22:11:13 /IDPLOAD VALUE=0x50 ; was 0x40<br />
<br />
* November 25, 2015, rear fast threshold raised to 0xA0<br />
<br />
2015-330-00:28:40 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-330-00:28:49 /IDPLOAD VALUE=0xA0 ; was 0x90<br />
<br />
* December 28, 2015, rear fast threshold raised to 0xB0<br />
<br />
2015-362-07:44:19 start idib_chg_thrshld (5, REAR, FAST, 0xB0) ; Was 0xA0<br />
<br />
* January 15, 2016, front slow threshold raised to 0x80<br />
<br />
2016-015-01:46:23 start idib_chg_thrshld (5, FRONT, FAST, 0x80)<br />
2016-015-01:46:27 /IDPUDUMPTABL TABLE=DIBTBL5<br />
2016-015-01:46:27 /IDPUTABLE5 OFFSET=FRONTFASTDAC<br />
2016-015-01:46:35 /IDPLOAD VALUE=0x80<br />
<br />
Post 2016 anneal<br />
* This detector is off<br />
<br />
* 2017 April 3: Turned on in response to high solar activity. HV was raised to ~1000V at 16:25. It was decided to adjust the threshold on the following day. <br />
<br />
* 2017 April 4: At the start of AOS of the first pass, the SSR fill was 79.2%. Detector 5 front slow valid started around 19500 counts with the threshold at 0x70, and dropped to about 18400 counts when we brought up the threshold to 0xC0. The increase to 0xFF was during the AGO pass right after, so we didn't have live monitor rates available. Due to high SSR fill level (>70%), D5 was turned off. <br />

<br />
===Post 2014 Anneal===<br />
<br />
Detector 8 is SEGMENTED after the 2014 anneal!<br />
<br />
On March 13, 2015 the rear fast threshold was changed.<br />
<br />
15-072-22:05:41 /IDPUTABLE8 OFFSET=REARFASTDAC<br />
15-072-22:05:56 /IDPLOAD VALUE=0x55<br />
<br />
* On April 7 2015, the rear fast threshold was changed due to extremely low livetime in the rear segment. It is not clear if this helped; the action will probably be repeated.<br />
<br />
15-097-19:57:24 /IDPUTABLE8 OFFSET=REARFASTDAC<br />
15-097-19:57:37 /IDPLOAD VALUE=0x70 ; was 0x65<br />
<br />
* On April 9 2015, the rear fast threshold was changed due to low livetime in the rear segment.<br />
<br />
15-099-17:38:09 /IDPUTABLE8 OFFSET=REARFASTDAC<br />
15-099-17:38:23 /IDPLOAD VALUE=0x80 ; was 0x70<br />
<br />
* On April 13 at 17:47UT we changed the Rear Fast threshold for detector 8.<br />
<br />
15-103-17:46:36 /IDPUTABLE8 OFFSET=REARFASTDAC<br />
15-103-17:46:47 /IDPLOAD VALUE=0x90 ; was 0x80<br />
<br />
* On April 14 at 17:25 UT we changed the Rear Fast threshold for detector 8.<br />
<br />
15-104-17:25:11 /IDPUTABLE8 OFFSET=REARFASTDAC<br />
15-104-17:25:22 /IDPLOAD VALUE=0xA0 ; was 0x90<br />
<br />
* On April 24 at 19:14 UT Rear Fast Threshold was increased.<br />
<br />
15-114-19:14:10 /IDPUTABLE8 OFFSET=REARFASTDAC<br />
15-114-19:14:20 /IDPLOAD VALUE=0xB0 ; was 0xA0<br />
<br />
* On May 4 at 20:49 UT Rear Fast Threshold was increased<br />
<br />
15-124-20:49:54 /IDPUTABLE8 OFFSET=REARFASTDAC<br />
15-124-20:50:09 /IDPLOAD VALUE=0xC0 ; was 0xB0<br />
<br />
* On May 15 the front slow threshold was increased<br />
<br />
2015-135-21:36:06 /IDPUTABLE8 OFFSET=FRONTSLOWDAC <br />
2015-135-21:36:25 /IDPLOAD VALUE=0x15 ; was 0x0C<br />
<br />
* On June 11 2015 the front fast threshold was raised because the fast rates were high and the livetime was low. This action was NOT successful in reducing the fast rates -- they dropped ever so slightly but not much. Therefore, the livetime remained low.<br />
<br />
* Late July 2015: D8 rear has not been returning good data since mid-May, but it was noticed that its fast threshold was never turned up all the way. On July 24 2015 the rear fast threshold was maxed out to see if that recovered a usable level of events from this detector. Unfortunately, it was not successful. <br />
2015-205-17:21:40 /IDPUTABLE8 OFFSET=REARFASTDAC<br />

<div>This page contains information about changes/issues for RHESSI detector 5 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 5 anneal 2012]]<br />
<br />
===Notes===<br />
<br />
* After the 2014 anneal, detector 5 is UNSEGMENTED.<br />
<br />
* A tweak shortly after the anneal was completed:<br />
G5 front slow to 0x80 (was 0x70) on 2014 Aug. 14 after 03:40 UTC<br />
<br />
* In late December 2014 some weak signal of segmentation were seen on G5. On January 5, 2015 at 14:57 UTC we set new values for the front fast and front slow thresholds on this detector. We need to keep an eye on its behaviour. Detector 5 is now weakly SEGMENTED.<br />
<br />
G5 front slow to 0x0C (was 0x80) on 2015 Jan. 5 after 14:57 UTC<br />
G5 front fast to 0x2E (was 0x60) on 2015 Jan. 5 after 14:57 UTC<br />
<br />
* On 2014 Jan 8, the rear fast threshold was raised since fast counts were eating up a lot of livetime.<br />
<br />
15-008-17:44:15 /IDPULOAD VALUE=0x50 ;(was 0x45)<br />
<br />
* On 2015 May 26 starting at 19:15:09 we increased the rear fast threshold by 0x08<br />
<br />
2015-146-19:15:09 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-146-19:15:21 /IDPLOAD VALUE=0x58 ; was 0x50<br />
<br />
* Aug. 24, 2015: The rear fast threshold was raised, successfully bringing the livetime up to >75%.<br />
2015-236-20:46:37 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-236-20:46:59 /IDPLOAD VALUE=0x70 ; was 0x58<br />
<br />
* On October 8, the front fast threshold was raised to try and raise livetime. Prior to these changes, D5 front livetime was at ~30%. As the changes were made on a BGS pass, the D5 front fast rates fell from 131k to 2100, and the livetimes rose accordingly, so the changes were successful. <br />
<br />
2015-281-21:49:25 /IDPUTABLE5 OFFSET=FRONTFASTDAC<br />
2015-281-21:49:37 /IDPLOAD VALUE=0x40 ; was 0x2E<br />
<br />
* The rear fast threshold was also raised on Oct. 9, for the usual reason. This worked, bringing the livetime up to >80%, though it's slowly dropped in the days since and might need another boost soon.<br />
<br />
2015-282-23:02:49 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-282-23:02:58 /IDPLOAD VALUE=0x90 ; was 0x80<br />
<br />
* November 23, 2015, front fast threshold raised due to a rapid decrease of the livetime.<br />
<br />
2015-327-22:11:03 /IDPUTABLE5 OFFSET=FRONTFASTDAC <br />
2015-327-22:11:13 /IDPLOAD VALUE=0x50 ; was 0x40<br />
<br />
* November 25, 2015, rear fast threshold raised to 0xA0<br />
<br />
2015-330-00:28:40 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-330-00:28:49 /IDPLOAD VALUE=0xA0 ; was 0x90<br />
<br />

<br />
2015-362-07:44:19 start idib_chg_thrshld (5, REAR, FAST, 0xB0) ; Was 0xA0<br />
<br />

<br />

Post 2016 anneal<br />
* This detector is off<br />
<br />
* 2017 April 3: Turned on in response to high solar activity. HV was raised to ~1000V at 16:25. It was decided to adjust the threshold on the following day. <br />
<br />
* 2017 April 4: At the start of AOS of the first pass, the SSR fill was 79.2%. Detector 5 front slow valid started around 19500 counts with the threshold at 0x70, and dropped to about 18400 counts when we brought up the threshold to 0xC0. The increase to 0xFF was during the AGO pass right after, so we didn't have live monitor rates available. Due to high SSR fill level (>70%), D5 was turned off. <br />

<br />
=== Post 2014 Anneal ===<br />
<br />
Detector 1 is SEGMENTED following the 2014 anneal (yay!)<br />
<br />
* The rear fast threshold was changed on July 13 2015 due to dropping livetime in the rear:<br />
2015-194-16:33:58 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-194-16:34:12 /IDPLOAD VALUE=0x50 ; was 0x45<br />
<br />
* The rear fast threshold was changed on July 24 2015 due to low livetime. However, the change probably wasn't needed; the tohban hadn't noticed that a change had already been made a few days ago. The next tohban can reverse the change if desired.<br />
2015-205-17:18:59 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-205-17:19:08 /IDPLOAD VALUE=0x70 ; was 0x60<br />
<br />
* The rear fast threshold was changed on Sep 9 2015 due to low livetime.<br />
2015-252-17:51:10 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-252-17:51:17 /IDPLOAD VALUE=0x80 ; was 0x70<br />
<br />
* On October 8, 9, and 12, the rear fast threshold was raised three times to try and raise livetime. Results still need to be assessed.<br />
<br />
2015-281-21:50:13 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-281-21:50:24 /IDPLOAD VALUE=0xA0 ; was 0x90<br />

<br />
2015-285-21:51:28 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-285-21:51:37 /IDPLOAD VALUE=0xC0 ; was 0xB0<br />
<br />
* Also on October 12, the front fast threshold on D1 (and also D7) was raised. This is to try and top off the livetime used in the attenuator logic. It might not work, since the fast rates are not terribly high for this detector, in which case the change could be reversed by a future tohban. Check this and see..<br />

<div>This page contains information about changes/issues for RHESSI detector 5 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 5 anneal 2012]]<br />
<br />
===Notes===<br />
<br />
* After the 2014 anneal, detector 5 is UNSEGMENTED.<br />
<br />
* A tweak shortly after the anneal was completed:<br />
G5 front slow to 0x80 (was 0x70) on 2014 Aug. 14 after 03:40 UTC<br />
<br />
* In late December 2014 some weak signal of segmentation were seen on G5. On January 5, 2015 at 14:57 UTC we set new values for the front fast and front slow thresholds on this detector. We need to keep an eye on its behaviour. Detector 5 is now weakly SEGMENTED.<br />
<br />
G5 front slow to 0x0C (was 0x80) on 2015 Jan. 5 after 14:57 UTC<br />
G5 front fast to 0x2E (was 0x60) on 2015 Jan. 5 after 14:57 UTC<br />
<br />
* On 2014 Jan 8, the rear fast threshold was raised since fast counts were eating up a lot of livetime.<br />
<br />
15-008-17:44:15 /IDPULOAD VALUE=0x50 ;(was 0x45)<br />
<br />
* On 2015 May 26 starting at 19:15:09 we increased the rear fast threshold by 0x08<br />
<br />
2015-146-19:15:09 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-146-19:15:21 /IDPLOAD VALUE=0x58 ; was 0x50<br />
<br />
* Aug. 24, 2015: The rear fast threshold was raised, successfully bringing the livetime up to >75%.<br />
2015-236-20:46:37 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-236-20:46:59 /IDPLOAD VALUE=0x70 ; was 0x58<br />
<br />
* On October 8, the front fast threshold was raised to try and raise livetime. Prior to these changes, D5 front livetime was at ~30%. As the changes were made on a BGS pass, the D5 front fast rates fell from 131k to 2100, and the livetimes rose accordingly, so the changes were successful. <br />
<br />
2015-281-21:49:25 /IDPUTABLE5 OFFSET=FRONTFASTDAC<br />
2015-281-21:49:37 /IDPLOAD VALUE=0x40 ; was 0x2E<br />
<br />
* The rear fast threshold was also raised on Oct. 9, for the usual reason. This worked, bringing the livetime up to >80%, though it's slowly dropped in the days since and might need another boost soon.<br />
<br />
2015-282-23:02:49 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-282-23:02:58 /IDPLOAD VALUE=0x90 ; was 0x80<br />
<br />
* November 23, 2015, front fast threshold raised due to a rapid decrease of the livetime.<br />
<br />
2015-327-22:11:03 /IDPUTABLE5 OFFSET=FRONTFASTDAC <br />
2015-327-22:11:13 /IDPLOAD VALUE=0x50 ; was 0x40<br />
<br />
* November 25, 2015, rear fast threshold raised to 0xA0<br />
<br />
2015-330-00:28:40 /IDPUTABLE5 OFFSET=REARFASTDAC<br />
2015-330-00:28:49 /IDPLOAD VALUE=0xA0 ; was 0x90<br />
<br />
* December 28, 2015, rear fast threshold raised to 0xB0<br />
<br />
2015-362-07:44:19 start idib_chg_thrshld (5, REAR, FAST, 0xB0) ; Was 0xA0<br />
<br />
* January 15, 2016, front slow threshold raised to 0x80<br />
<br />
2016-015-01:46:23 start idib_chg_thrshld (5, FRONT, FAST, 0x80)<br />

* This detector is off<br />
<br />
* 2017 April 3: Turned on in response to high solar activity. HV was raised to ~1000V at 16:25 and then up to ~2000V at 19:45 UT. It was decided to adjust the threshold on the following day. <br />
<br />
* 2017 April 4: At the start of AOS of the first pass, the SSR fill was 79.2%. Detector 5 front slow valid started around 19500 counts with the threshold at 0x70, and dropped to about 18400 counts when we brought up the threshold to 0xC0. The increase to 0xFF was during the AGO pass right after, so we didn't have live monitor rates available. Due to high SSR fill level (>70%), D5 was turned off. <br />

<br />
=== Post 2014 Anneal ===<br />
<br />
Detector 1 is SEGMENTED following the 2014 anneal (yay!)<br />
<br />
* The rear fast threshold was changed on July 13 2015 due to dropping livetime in the rear:<br />
2015-194-16:33:58 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-194-16:34:12 /IDPLOAD VALUE=0x50 ; was 0x45<br />
<br />
* The rear fast threshold was changed on July 24 2015 due to low livetime. However, the change probably wasn't needed; the tohban hadn't noticed that a change had already been made a few days ago. The next tohban can reverse the change if desired.<br />
2015-205-17:18:59 /IDPUTABLE1 OFFSET=REARFASTDAC<br />

== Solar Activity ==<br />
<br />
The Sun was active this week, producing seven M-class flares. Currently there are five AR on disk, but four of them are expected to rotate off the disk very soon.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 39 30 7 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 21 17 5 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 12 11 2 0<br />
<br />
There were RHESSI flares/GOES flares 188 / 76<br />
over the time range 28-Mar-17 04-Apr-17<br />
<br />
<br />
== Memory Management ==<br />
<br />
Early the week, the SSR was at 0% at the end of each day's contacts. In response to the high solar activities and the turn-on of some detectors, the SSR reached 75% and the decimation was switched to active/vigorous from normal/vigorous.<br />
<br />
== Spacecraft Status ==<br />
<br />
Detectors 3 and 6 are recording events. Due to the increased solar activities, D1, 5 and 8 were turned on. D5 was turned off soon due to its unexpectedly high event rate. <br />
<br />
The cold tips are 129.5 and 128.0 K as of 5-Apr-2017. The cold plates, 1 and 2 are 153.3 and 151.8 K. Cryocooler power is steady at 76W. <br />
See:<br />

<br />
for a summary plot of recent temperatures, efficiencies and accelerometer values.<br />
<br />
== Data Gaps ==<br />
<br />
Relatively large (>300 sec) data gaps as follows:<br />
<br />
GAPS IN APP_ID = 102 (VC3-MONITOR RATES) WITH PACKET RATE LT 30<br />

<br />
== Detector issues ==<br />
<br />
Detectors 1, 3, 6 and 8 are powered on, and are recording events. <br />
<br />
There are counts coming in the maximum energy channel on D6. Its a "new" phenomenon, and we're not sure where its coming from or why. Don't think its damage, no high leakage current or resets. Next Tohban keep and eye on it and maybe try some tests to see where it comes from. Adjusting HV was suggested. <br />

== Detector issues ==<br />
<br />
On December 12 (DOY 347), D3 rear fast threshold was raised for better livetimes.<br />
<br />
16-347-16:52:42 /IDPULOAD VALUE=0xC0 ; was 0xB0<br />
16-347-16:56:14 /IDPULOAD VALUE=0xD0 ; was 0xC0<br />
<br />
On 12 December 2016, D9 front slow threshold was raised from 0x0C to 0x15 for a better SSR fill level. The front fast threshold was also raised for better livetimes.<br />
<br />
2016-347-16:53:13 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
2016-347-16:53:23 /IDPULOAD VALUE=0x50 ; was 0x40<br />

2016-347-16:54:19 /IDPULOAD VALUE=0x15 ; was 0x0C<br />
<br />
On Wednesday 14 December, the event telemetry during eclipses was disabled. The tohban also requested increasing the D9 front slow threshold from 0x15 to 0x30 but it was determined, during the Ops meeting, that it is not necessary. So the threshold remains at 0x15.<br />

<div>This page contains information about changes/issues for RHESSI detector 9 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 9 anneal 2012]]<br />
<br />
===Post 2014 Anneal===<br />
<br />
Detector 9 is SEGMENTED after the 2014 anneal!<br />
<br />
* 2014 August 20: Due to sporadic noise in D9, the HV was dropped by 20 counts (now at 3600V). Commanding was at 20:57 UTC. This successfully quieted the noise. The noise was mainly fast counts, which cut drastically into the livetime.<br />
<br />
* 2014 October 8: This detector has started to show some periodical spikes during last couple of days. Still is not clear what is their origin. It seems to be periodic with the orbit. So far no action taken.<br />
<br />
* 2014 Oct 31: Elevated noise during the period of Oct 31 - Nov 2. The onset, as well as the abatement was sudden. No commanding was done and the noise returned to regular levels.<br />
<br />
* On 2015 Jan 8, the rear fast threshold was raised since fast counts were eating up a lot of livetime.<br />
<br />
15-008-17:45:50 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-008-17:46:04 /IDPULOAD VALUE=0x50 ;(was 0x45)<br />
<br />
* Rear fast counts are high again, so we raised the rear fast threshold by 16 steps, in two sets of 8, on the BGS pass starting at ~3:30 PST. The new value is 0x60 (was 0x50). Fast rates as eyeballed from the realtime data were approx 58,000 (pre-adjustment), 12,000 (after 8 steps up), and 1600 (after 16 steps up). Livetime percentages were approx 60%, 90%, and 98%, respectively.<br />
<br />
15-021-23:33:58 /idpudumptabl table=dibtbl9<br />
15-021-23:34:03 /idputable9 offset=rearfastdac<br />

15-021-23:36:47 /idputable9 offset=rearfastdac<br />
15-021-23:36:55 /idpuload value=0x60<br />
<br />
* The rear fast threshold was raised again for the same reasons as the last two adjustments. The threshold was raised in two jumps of hex 8 each.<br />
15-057-18:43:13 /IDPUTABLE9 OFFSET=rearfastDAC<br />
15-057-18:45:14 /IDPLOAD VALUE=0x68<br />
<br />
15-057-20:21:52 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-057-20:22:09 /IDPLOAD VALUE=0x70<br />
<br />
* Rear fast threshold changed again, usual reason.<br />
15-064-19:39:50 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-064-19:40:12 /IDPLOAD VALUE=0x80 ; was 0x70<br />
<br />
* And again, on March 11, 2015.<br />
2015-070-22:46:04 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
2015-070-22:46:19 /IDPLOAD VALUE=0x90<br />
<br />
* On March 13, 2015 the rear fast threshold was changed again<br />
15-072-22:06:18 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-072-22:06:31 /IDPLOAD VALUE=0xA0<br />
<br />
* And then again, on March 16, 2015.<br />
15-075-19:24:13 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-075-19:24:28 /IDPLOAD VALUE=0xB0<br />
<br />
* And then again, on March 18, 2015.<br />
15-077-TBD /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-077-TBD /IDPLOAD VALUE=0xC0<br />
<br />
* And again, on March 25, 2015.<br />
15-084-21:07:00 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-084-21:07:14 /IDPLOAD VALUE=0xFF<br />
<br />
* In addition we change the HV on March 25, 2015:<br />
15-084-19:26:07 /ihvdac detector=9, voltage=176<br />
15-084-19:27:17 /ihvdac detector=9, voltage=166<br />
15-084-19:28:33 /ihvdac detector=9, voltage=156<br />
15-084-21:05:17 /ihvdac detector=9, voltage=136 (2622 V)<br />
<br />
* As of early April, detector 9 rear segment is now essentially non functional. Rear fast rates have increased to the point where livetime dropped to zero, and the fast threshold is already turned all the way up so we have no way to control those rates. The front segment appears to be operating normally, though its fast AND slow rates are high (but not worringly so).<br />
<br />
* 2015 April 7: To deal with slightly reduced livetime in the FRONT segment, we changed the front fast threshold. This does NOT seem to have had an effect!!<br />
15-097-19:58:06 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
15-097-19:58:14 /IDPLOAD VALUE=0x30 ; was 0x22<br />
<br />
* 2015 April 14: We increase the Front Slow Threshold just to reduce the values on the front slow valid counts<br />
15-104-14:09:00 /IDPUTABLE9 OFFSET=FRONTSLOWDAC<br />
15-104-14:09:12 /IDPLOAD VALUE=0x1A<br />
<br />
* 2015 May 13: D9 front fast was increased <br />
2015-133-19:09:39 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />

* On June 11 2015 the front fast threshold was raised because the fast rates were high and the livetime was low. This action was DID reduce the fast rates but did NOT increase the livetime much! D9 now does not show high fast rates, slow rates, or resets, but yet the livetime is quite low.<br />
<br />
* On August 20 2015 the front fast threshold was raised in an attempt to gain livetime, which was at ~15%. This was unsuccessful.<br />

<br />
* On August 20 2015 the rear segment started dumping a huge number of ULD events into the SSR, filling it. Once the problem was pinpointed, D9 events were disabled entirely on the 21st. D9 HV was turned down to 1800V, then 900V, then 800V, in an attempt to bring down the resets. This brought resets down from 30k to 23k and did, indeed, quiet the ULDs. The detector remained segmented. At one point the threshold change to D9 front was reversed to see if that had caused the problem (it hadn't); the threshold change was then re-implemented. Events were turned briefly back on on Aug. 24 and then off, although no danger signs were seen. As of Aug. 25, D9 events are still off. Approximate commanding times are below:<br />
August 21:<br />
1:15 pm PDT: D9 front fast threshold to 0x60 (was 0x90).<br />
2:50 pm PDT: D9 front and rear events disabled.<br />
4:30 pm PDT: HV drop of ~400V, performed in two steps, to 1838V. No change to resets (30k). RTS load to keep D9 events from being re-enabled after eclipse. D9 fast and slow thresholds to max.<br />
6:00 pm PDT: HV drop to ~900V and then again to ~800V. Rear resets before and after are 30k then 25.7k then 23.5k. D9 front fast threshold returned to 0x90.<br />
<br />
* On August 24 2015 D9 events were enabled at 20:42:45 UTC in order to check whether we would still dump too many events into the SSR. The write pointer speed didn't seem to change with this action (although it maybe did change with other detector threshold changes). We left D9 events on, knowing that they'd be turned off again at the next dawn due to the RTS load. As of Aug. 26, D9 events are still off.<br />

<br />
* On Sept 9-11, 2015, the rear D9 ULD rose, finally going crazy and maxing out on Sept 11. Since events were off, this wasn't noticed until Sept. 28. To try and avoid/mitigate potential damage to the detector, we lowered the HV on D9 on Sept. 29 PDT (Sept. 30 03:00 UTC) from ~800V to 490V. We briefly turned on events for G9 as well. Events were then turned off again at eclipse entry. The ULD event rate should be checked as soon as we get the monitor rate data on it. The detector stayed segmented.<br />

<br />
* D9 ULDs went haywire again, so we decided to turn off the HV and electronics for D9. On Oct 13 Jeremy removed all power from detector 9's HV and turned off DIB (Detector Interface Board) 9. This commanding was done October 13, 2015 at 18:22 UTC. It should be monitored to see if we get any noticeable changes to power or temperature diagnostics due to this.<br />

<div>This page contains information about changes/issues for RHESSI detector 3 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 3 anneal 2012]]<br />
<br />
===Post 2014 Anneal===<br />
<br />
Detector 3 is SEGMENTED following the 2014 anneal (yay!)<br />
<br />
* 2014-Aug-26: D3 is suffering a lot from the known light leak problem. This does not affect the quality of the data but greatly reduces livetime at times when light leaks in through the cryostat port. To alleviate this problem, the G3 rear fast threshold was raised from 0x45 to 0x50 at 2014-238-19:22:56 UTC. This didn't seem to fix the problem.<br />
<br />
* Another threshold change b/c of light leak:<br />
14-241-18:34:11 /IDPUTABLE3 REARFASTDAC ;Load address 0x25CC <br />
14-241-18:34:31 /IDPULOAD VALUE=0x60 ;Rear fast from ox50 to 0x60<br />
<br />
* Front Fast threshold increase due to light leak. This lowered fast counts and increased livetime<br />
2015-152-16:58:07 /IDPUTABLE3 OFFSET=FRONTFASTDAC<br />
2015-152-16:58:16 /IDPLOAD VALUE=0x30 ; was 0x22<br />
<br />
* The front fast threshold was increased on July 10 2015 due to low livetime due to high fast rates. This action was effective in raising the livetime.<br />
2015-191-19:20:47 /IDPUTABLE3 OFFSET=FRONTFASTDAC<br />
2015-191-19:20:58 /IDPLOAD VALUE=0x40 ; was 0x30<br />
<br />
* On Aug 20, 2015 the front fast threshold was raised in order to lower fast rates and free up livetime. This was successful: Livetime rose from ~50% to >90%.<br />
15-232-22:16:08 start idib_chg_thrshld (3, FRONT, FAST, 0x50)<br />
15-232-22:16:30 /IDPUDUMPTABL TABLE=DIBTBL3<br />
15-232-22:16:30 /IDPUTABLE3 OFFSET=FRONTFASTDAC<br />
15-232-22:16:41 /IDPLOAD VALUE=0x50<br />
<br />
* By Aug 24, 2015 rear livetime was so low that the detector had entered "reverse mode" where fast rates are not fully shown, and so fast threshold changes give the opposite effect to that you might expect. (Light leak shows up as livetime peaks, not valleys, in this mode.) The rear fast threshold was raised in two jumps. The first raise apparently increased fast rates and worsened livetime (due to this "reverse mode") but the second raise was successful in bringing down the fast rates and restoring livetime to ~64%.<br />
2015-236-20:45:42 /IDPUTABLE3 OFFSET=REARFASTDAC<br />

2015-237-00:03:48 /IDPLOAD VALUE=0x90 ; was 0x80<br />
<br />
* The front slow count rates were elevated, to try to bring them down we raised the slow front threshold by 0x10 on August 27th. This has an immediate effect lowering the slow front counts by a factor of 2. We also raised the front and rear fast threshold to increase the livetime.<br />
<br />

2015-239-21:13:33 /IDPLOAD VALUE=0x60 ; was 0x50<br />
<br />
*On Sept 14 2015, we raised the rear fast threshold on D3 from 0xA0 to 0xB0, to arrest a live-time decrease. Live time jumped fro 10 to 70%, but was bak to 40% in two days.<br />
<br />
2015-257-17:33:14 /IDPUTABLE3 OFFSET=REARFASTDAC<br />
2015-257-17:33:22 /IDPLOAD VALUE=0xB0 ; was 0xA0<br />
<br />
* Some threshold changes occurred during the tohban week of Sept 15-22.<br />
<br />
* On Sept 23, it was decided that the last changes to the slow threshold were probably too drastic, especially considering that the fast threshold was changed at the same time. We backed the front slow threshold back down to 0x1C, which is what it had been before the last adjustment. This needs to be monitored to see how D3 operates in this state, and keep an eye on the slow rates + SSR. UPDATE Sept. 24: the D3 event rate did not significantly change with this threshold drop. Livetime is still ~90% (same as before the drop) so I think this is a stable, working condition. If more livetime is desired, the fast threshold could be raised again.<br />
<br />

2015-266-19:24:12 /IDPLOAD VALUE=0x1C ;was 0x80<br />
<br />
* 2nd October 2015: We returned detector G3 Front Slow threshold to the nominal value of 0x0C (was 0x1C). When we did this, the front slow valids jumped from ~1680 cps to ~3800 cps. We left it this way, over the weekend, but keept a close eye on it.<br />

<br />
* On October 7, Detector 3's front fast threshold was increased from 0x80 to 0xD0 at 280-22:13:38 UTC. This was due to high fast rates and low livetime in that detector. This worked, increasing D3 front LT to ~85%.<br />
<br />

<br />
* On October 8 and 9, the rear fast threshold was raised to try and raise livetime. This threshold is now maxed out, but it wasn't enough to lower the fast rates enough to get appreciable LT back. The rear segment is at essentially zero livetime, so it's not really functional.<br />

* 2015 December 10, power-cycling: D3's HV was ramped to 0.0 v and the Detector Interface Board #3 was powered off for one orbit. The detector segmented once a few tens of volts were applied. We ramped it back up to 1000 V by the end of the pass. The front livetime returned to ~78%, about the same as before the power cycle. If this power-cycling improved the detector status, we wanted to lower front slow threshold from 0xC0 to 0xB0 in order to better support GRIPS (0xC0 is 35 keV). However, D3 spectrum showed no change after this power-cycling. So, no threshold change was made.<br />

<hr />
<div>This page contains information about changes/issues for RHESSI detector 9 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 9 anneal 2012]]<br />
<br />
===Post 2014 Anneal===<br />
<br />
Detector 9 is SEGMENTED after the 2014 anneal!<br />
<br />
* 2014 August 20: Due to sporadic noise in D9, the HV was dropped by 20 counts (now at 3600V). Commanding was at 20:57 UTC. This successfully quieted the noise. The noise was mainly fast counts, which cut drastically into the livetime.<br />
<br />
* 2014 October 8: This detector has started to show some periodical spikes during last couple of days. Still is not clear what is their origin. It seems to be periodic with the orbit. So far no action taken.<br />
<br />
* 2014 Oct 31: Elevated noise during the period of Oct 31 - Nov 2. The onset, as well as the abatement was sudden. No commanding was done and the noise returned to regular levels.<br />
<br />
* On 2015 Jan 8, the rear fast threshold was raised since fast counts were eating up a lot of livetime.<br />
<br />
15-008-17:45:50 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-008-17:46:04 /IDPULOAD VALUE=0x50 ;(was 0x45)<br />
<br />
* Rear fast counts are high again, so we raised the rear fast threshold by 16 steps, in two sets of 8, on the BGS pass starting at ~3:30 PST. The new value is 0x60 (was 0x50). Fast rates as eyeballed from the realtime data were approx 58,000 (pre-adjustment), 12,000 (after 8 steps up), and 1600 (after 16 steps up). Livetime percentages were approx 60%, 90%, and 98%, respectively.<br />

<br />
* The rear fast threshold was raised again for the same reasons as the last two adjustments. The threshold was raised in two jumps of hex 8 each.<br />

2015-070-22:46:19 /IDPLOAD VALUE=0x90<br />
<br />

15-072-22:06:31 /IDPLOAD VALUE=0xA0<br />

15-075-19:24:28 /IDPLOAD VALUE=0xB0<br />

15-077-TBD /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-077-TBD /IDPLOAD VALUE=0xC0<br />
<br />
* And again, on March 25, 2015.<br />
15-084-21:07:00 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-084-21:07:14 /IDPLOAD VALUE=0xFF<br />
<br />
* In addition we change the HV on March 25, 2015:<br />
15-084-19:26:07 /ihvdac detector=9, voltage=176<br />
15-084-19:27:17 /ihvdac detector=9, voltage=166<br />
15-084-19:28:33 /ihvdac detector=9, voltage=156<br />
15-084-21:05:17 /ihvdac detector=9, voltage=136 (2622 V)<br />
<br />
* As of early April, detector 9 rear segment is now essentially non functional. Rear fast rates have increased to the point where livetime dropped to zero, and the fast threshold is already turned all the way up so we have no way to control those rates. The front segment appears to be operating normally, though its fast AND slow rates are high (but not worringly so).<br />
<br />
* 2015 April 7: To deal with slightly reduced livetime in the FRONT segment, we changed the front fast threshold. This does NOT seem to have had an effect!!<br />
15-097-19:58:06 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
15-097-19:58:14 /IDPLOAD VALUE=0x30 ; was 0x22<br />
<br />
* 2015 April 14: We increase the Front Slow Threshold just to reduce the values on the front slow valid counts<br />

15-104-14:09:12 /IDPLOAD VALUE=0x1A<br />
<br />
* 2015 May 13: D9 front fast was increased <br />

2015-133-19:09:52 /IDPLOAD VALUE=0x40 ; was 0x30<br />
<br />
* On June 11 2015 the front fast threshold was raised because the fast rates were high and the livetime was low. This action was DID reduce the fast rates but did NOT increase the livetime much! D9 now does not show high fast rates, slow rates, or resets, but yet the livetime is quite low.<br />
<br />
* On August 20 2015 the front fast threshold was raised in an attempt to gain livetime, which was at ~15%. This was unsuccessful.<br />

15-232-22:21:38 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
15-232-22:21:46 /IDPLOAD VALUE=0x90<br />
<br />
* On August 20 2015 the rear segment started dumping a huge number of ULD events into the SSR, filling it. Once the problem was pinpointed, D9 events were disabled entirely on the 21st. D9 HV was turned down to 1800V, then 900V, then 800V, in an attempt to bring down the resets. This brought resets down from 30k to 23k and did, indeed, quiet the ULDs. The detector remained segmented. At one point the threshold change to D9 front was reversed to see if that had caused the problem (it hadn't); the threshold change was then re-implemented. Events were turned briefly back on on Aug. 24 and then off, although no danger signs were seen. As of Aug. 25, D9 events are still off. Approximate commanding times are below:<br />
August 21:<br />
1:15 pm PDT: D9 front fast threshold to 0x60 (was 0x90).<br />
2:50 pm PDT: D9 front and rear events disabled.<br />
4:30 pm PDT: HV drop of ~400V, performed in two steps, to 1838V. No change to resets (30k). RTS load to keep D9 events from being re-enabled after eclipse. D9 fast and slow thresholds to max.<br />
6:00 pm PDT: HV drop to ~900V and then again to ~800V. Rear resets before and after are 30k then 25.7k then 23.5k. D9 front fast threshold returned to 0x90.<br />
<br />
* On August 24 2015 D9 events were enabled at 20:42:45 UTC in order to check whether we would still dump too many events into the SSR. The write pointer speed didn't seem to change with this action (although it maybe did change with other detector threshold changes). We left D9 events on, knowing that they'd be turned off again at the next dawn due to the RTS load. As of Aug. 26, D9 events are still off.<br />
2015-236-20:42:45 /itmon value=AFE8 (Detector 9 events turn on)<br />
<br />
* On Sept 9-11, 2015, the rear D9 ULD rose, finally going crazy and maxing out on Sept 11. Since events were off, this wasn't noticed until Sept. 28. To try and avoid/mitigate potential damage to the detector, we lowered the HV on D9 on Sept. 29 PDT (Sept. 30 03:00 UTC) from ~800V to 490V. We briefly turned on events for G9 as well. Events were then turned off again at eclipse entry. The ULD event rate should be checked as soon as we get the monitor rate data on it. The detector stayed segmented.<br />
<br />

2015-273-03:01:09 /IHVDAC DETECTOR=9, VOLTAGE=26<br />
<br />
<br />
* D9 ULDs went haywire again, so we decided to turn off the HV and electronics for D9. On Oct 13 Jeremy removed all power from detector 9's HV and turned off DIB (Detector Interface Board) 9. This commanding was done October 13, 2015 at 18:22 UTC. It should be monitored to see if we get any noticeable changes to power or temperature diagnostics due to this.<br />

* D9 HV ramped up to 4000 V. The detector was segmented around 1700 V. We adjusted the rear fast threshold up from 0x45 to 0x60 then turned on events. <br />
<br />
* On Oct.17 (DOY 291), D9 rear fast threshold was raised from 0x60 to 0x90. In the following passes, it was lowered down to 0x70 and then raised back to 0x80.<br />

== Solar Activity ==<br />
<br />
The solar activity was extremely low, remained at B-level throughout the week. There is only one AR on disk, and so the solar activity is expected to remain low next week.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 3 0 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 1 0 0 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 1 0 0 0<br />
<br />
There were RHESSI flares/GOES flares 7 / 3<br />
over the time range 18-Oct-16 25-Oct-16<br />
<br />
== Memory Management ==<br />
<br />
The SSR was at 0% at the end of BGS passes. <br />
<br />
== Spacecraft Status ==<br />
<br />
The spacecraft has remained stable. Detectors 3 and 9 continued recording events. The cold tips temperature have come down further, and they are currently 117.6 and 115.9 K as of 2016-10-26. The cold plates, 1 and 2 are 142.0 and 140.8 K. <br />
<br />
== Data Gaps ==<br />

== Solar Activity ==<br />
<br />
The solar activity was low, mostly B-flare activity with several C-flares. There are only two ARs on disk, and we expect to see low activity next week.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 21 4 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 13 4 0 0<br />

<br />
There were RHESSI flares/GOES flares 87 / 25<br />
over the time range 11-Oct-16 18-Oct-16<br />
<br />
<br />
== Memory Management ==<br />
<br />
The SSR was at 0% at the end of BGS passes. <br />
<br />
== Spacecraft Status ==<br />
<br />
On Thursday Oct.13, Detector 8 was turned off and Detector 9 was turned on (HV ramped up to ~3000V). Currently, Detectors 3 and 9 are recording events. The cold tips temperature have come down a little partly due to day light changes. They are currently 119.0 and 117.0 K as of 2016-10-19. The cold plates, 1 and 2 are 143.8 and 142.1 K. The battery looks good, well above 26V.<br />
<br />
== Data Gaps ==<br />
There were two relatively large data gaps in addition to short (typically 300 s) data gaps.<br />

<br />
<br />
== Detector issues ==<br />
<br />
Detectors 3 and 9 are powered on, and are recording events. On Oct.17 (DOY 291), D9 rear fast threshold was raised from 0x60 to 0x90. In the following passes, it was lowered down to 0x70 and then raised back to 0x80. Currently the livetime is still low, reaching 5%.<br />

2016-291-20:59:57 /IDPULOAD VALUE=0x80 ; was 0x70<br />
<br />
== Notes ==<br />
<br />
Because there is no marginal difference between Detectors 8 and 9, the team decided to keep Detector 9 for a while.<br />

<div>This page contains information about changes/issues for RHESSI detector 9 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 9 anneal 2012]]<br />
<br />
===Post 2014 Anneal===<br />
<br />
Detector 9 is SEGMENTED after the 2014 anneal!<br />
<br />
* 2014 August 20: Due to sporadic noise in D9, the HV was dropped by 20 counts (now at 3600V). Commanding was at 20:57 UTC. This successfully quieted the noise. The noise was mainly fast counts, which cut drastically into the livetime.<br />
<br />
* 2014 October 8: This detector has started to show some periodical spikes during last couple of days. Still is not clear what is their origin. It seems to be periodic with the orbit. So far no action taken.<br />
<br />
* 2014 Oct 31: Elevated noise during the period of Oct 31 - Nov 2. The onset, as well as the abatement was sudden. No commanding was done and the noise returned to regular levels.<br />
<br />
* On 2015 Jan 8, the rear fast threshold was raised since fast counts were eating up a lot of livetime.<br />
<br />
15-008-17:45:50 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-008-17:46:04 /IDPULOAD VALUE=0x50 ;(was 0x45)<br />
<br />
* Rear fast counts are high again, so we raised the rear fast threshold by 16 steps, in two sets of 8, on the BGS pass starting at ~3:30 PST. The new value is 0x60 (was 0x50). Fast rates as eyeballed from the realtime data were approx 58,000 (pre-adjustment), 12,000 (after 8 steps up), and 1600 (after 16 steps up). Livetime percentages were approx 60%, 90%, and 98%, respectively.<br />
<br />
15-021-23:33:58 /idpudumptabl table=dibtbl9<br />
15-021-23:34:03 /idputable9 offset=rearfastdac<br />
15-021-23:34:34 /idpuload value=0x58<br />
<br />
15-021-23:36:47 /idputable9 offset=rearfastdac<br />
15-021-23:36:55 /idpuload value=0x60<br />
<br />
* The rear fast threshold was raised again for the same reasons as the last two adjustments. The threshold was raised in two jumps of hex 8 each.<br />
15-057-18:43:13 /IDPUTABLE9 OFFSET=rearfastDAC<br />
15-057-18:45:14 /IDPLOAD VALUE=0x68<br />
<br />
15-057-20:21:52 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-057-20:22:09 /IDPLOAD VALUE=0x70<br />
<br />
* Rear fast threshold changed again, usual reason.<br />
15-064-19:39:50 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-064-19:40:12 /IDPLOAD VALUE=0x80 ; was 0x70<br />
<br />
* And again, on March 11, 2015.<br />
2015-070-22:46:04 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
2015-070-22:46:19 /IDPLOAD VALUE=0x90<br />
<br />
* On March 13, 2015 the rear fast threshold was changed again<br />
15-072-22:06:18 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-072-22:06:31 /IDPLOAD VALUE=0xA0<br />
<br />
* And then again, on March 16, 2015.<br />
15-075-19:24:13 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-075-19:24:28 /IDPLOAD VALUE=0xB0<br />
<br />
* And then again, on March 18, 2015.<br />
15-077-TBD /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-077-TBD /IDPLOAD VALUE=0xC0<br />
<br />
* And again, on March 25, 2015.<br />
15-084-21:07:00 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-084-21:07:14 /IDPLOAD VALUE=0xFF<br />
<br />
* In addition we change the HV on March 25, 2015:<br />
15-084-19:26:07 /ihvdac detector=9, voltage=176<br />
15-084-19:27:17 /ihvdac detector=9, voltage=166<br />
15-084-19:28:33 /ihvdac detector=9, voltage=156<br />
15-084-21:05:17 /ihvdac detector=9, voltage=136 (2622 V)<br />
<br />
* As of early April, detector 9 rear segment is now essentially non functional. Rear fast rates have increased to the point where livetime dropped to zero, and the fast threshold is already turned all the way up so we have no way to control those rates. The front segment appears to be operating normally, though its fast AND slow rates are high (but not worringly so).<br />
<br />
* 2015 April 7: To deal with slightly reduced livetime in the FRONT segment, we changed the front fast threshold. This does NOT seem to have had an effect!!<br />
15-097-19:58:06 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
15-097-19:58:14 /IDPLOAD VALUE=0x30 ; was 0x22<br />
<br />
* 2015 April 14: We increase the Front Slow Threshold just to reduce the values on the front slow valid counts<br />
15-104-14:09:00 /IDPUTABLE9 OFFSET=FRONTSLOWDAC<br />
15-104-14:09:12 /IDPLOAD VALUE=0x1A<br />
<br />
* 2015 May 13: D9 front fast was increased <br />
2015-133-19:09:39 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
2015-133-19:09:52 /IDPLOAD VALUE=0x40 ; was 0x30<br />
<br />
* On June 11 2015 the front fast threshold was raised because the fast rates were high and the livetime was low. This action was DID reduce the fast rates but did NOT increase the livetime much! D9 now does not show high fast rates, slow rates, or resets, but yet the livetime is quite low.<br />
<br />
* On August 20 2015 the front fast threshold was raised in an attempt to gain livetime, which was at ~15%. This was unsuccessful.<br />
15-232-22:21:09 start idib_chg_thrshld (9, FRONT, FAST, 0x90)<br />
15-232-22:21:38 /IDPUDUMPTABL TABLE=DIBTBL9<br />
15-232-22:21:38 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
15-232-22:21:46 /IDPLOAD VALUE=0x90<br />
<br />
* On August 20 2015 the rear segment started dumping a huge number of ULD events into the SSR, filling it. Once the problem was pinpointed, D9 events were disabled entirely on the 21st. D9 HV was turned down to 1800V, then 900V, then 800V, in an attempt to bring down the resets. This brought resets down from 30k to 23k and did, indeed, quiet the ULDs. The detector remained segmented. At one point the threshold change to D9 front was reversed to see if that had caused the problem (it hadn't); the threshold change was then re-implemented. Events were turned briefly back on on Aug. 24 and then off, although no danger signs were seen. As of Aug. 25, D9 events are still off. Approximate commanding times are below:<br />
August 21:<br />
1:15 pm PDT: D9 front fast threshold to 0x60 (was 0x90).<br />
2:50 pm PDT: D9 front and rear events disabled.<br />
4:30 pm PDT: HV drop of ~400V, performed in two steps, to 1838V. No change to resets (30k). RTS load to keep D9 events from being re-enabled after eclipse. D9 fast and slow thresholds to max.<br />
6:00 pm PDT: HV drop to ~900V and then again to ~800V. Rear resets before and after are 30k then 25.7k then 23.5k. D9 front fast threshold returned to 0x90.<br />
<br />
* On August 24 2015 D9 events were enabled at 20:42:45 UTC in order to check whether we would still dump too many events into the SSR. The write pointer speed didn't seem to change with this action (although it maybe did change with other detector threshold changes). We left D9 events on, knowing that they'd be turned off again at the next dawn due to the RTS load. As of Aug. 26, D9 events are still off.<br />
2015-236-20:42:45 /itmon value=AFE8 (Detector 9 events turn on)<br />
<br />
* On Sept 9-11, 2015, the rear D9 ULD rose, finally going crazy and maxing out on Sept 11. Since events were off, this wasn't noticed until Sept. 28. To try and avoid/mitigate potential damage to the detector, we lowered the HV on D9 on Sept. 29 PDT (Sept. 30 03:00 UTC) from ~800V to 490V. We briefly turned on events for G9 as well. Events were then turned off again at eclipse entry. The ULD event rate should be checked as soon as we get the monitor rate data on it. The detector stayed segmented.<br />
<br />
2015-273-03:00:43 /itmon value=AFE8 (Detector 9 events on)<br />
2015-273-03:01:09 /IHVDAC DETECTOR=9, VOLTAGE=26<br />
<br />
<br />
* D9 ULDs went haywire again, so we decided to turn off the HV and electronics for D9. On Oct 13 Jeremy removed all power from detector 9's HV and turned off DIB (Detector Interface Board) 9. This commanding was done October 13, 2015 at 18:22 UTC. It should be monitored to see if we get any noticeable changes to power or temperature diagnostics due to this.<br />
<br />
2015-286-18:21:43 /IHVDAC DETECTOR=9, VOLTAGE=0<br />
2015-286-18:22:48 start idib_single_off(9)<br />
<br />
===Post 2016 Anneal===<br />
<br />
* D9 HV ramped up to 4000 V. The detector was segmented around 1700 V. We adjusted the rear fast threshold up from 0x45 to 0x60 then turned on events. <br />
<br />
* On Oct.17 (DOY 291), D9 rear fast threshold was raised from 0x60 to 0x90. In the following passes, it was lowered down to 0x70 and then raised back to 0x80.<br />
2016-291-17:40:26 /IDPULOAD VALUE=0x90 ; was 0x60<br />
2016-291-19:22:08 /IDPULOAD VALUE=0x70 ; was 0x90<br />
2016-291-20:59:57 /IDPULOAD VALUE=0x80 ; was 0x70<br />

== Solar Activity ==<br />
<br />
The solar activity was low, mostly B-flare activity with several C-flares. There are only two ARs on disk, and we expect to see low activity next week.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 21 4 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 13 4 0 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 7 4 0 0<br />
<br />
There were RHESSI flares/GOES flares 87 / 25<br />
over the time range 11-Oct-16 18-Oct-16<br />
<br />
<br />
== Memory Management ==<br />
<br />
The SSR was at 0% at the end of BGS passes. <br />
<br />
== Spacecraft Status ==<br />
<br />
On Thursday, Detector 8 was turned off and Detector 9 was turned on. Currently, Detectors 3 and 9 are recording events. The cold tips are currently 119.0 and 117.0 K as of 2016-10-19. The cold plates, 1 and 2 are 143.8 and 142.1 K. <br />
<br />
== Data Gaps ==<br />
There were two relatively large data gaps in addition to short (typically 300 s) data gaps.<br />

== Detector issues ==<br />
<br />
Detectors 3 and 9 are powered on, and are recording events. On Oct.17 (DOY 291), D9 rear fast threshold was raised from 0x60 to 0x90. In the following passes, it was lowered down to 0x70 and then raised back to 0x80. Currently the livetime is still low, reaching 5%.<br />

<div>This page contains information about changes/issues for RHESSI detector 1 after the 2014 anneal. Detector 1 updates from 2012-mid 2014 can be found here: [[Detector 1 anneal 2012]]<br />
<br />
=== Post 2014 Anneal ===<br />
<br />
Detector 1 is SEGMENTED following the 2014 anneal (yay!)<br />
<br />
* The rear fast threshold was changed on July 13 2015 due to dropping livetime in the rear:<br />
2015-194-16:33:58 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-194-16:34:12 /IDPLOAD VALUE=0x50 ; was 0x45<br />
<br />
* The rear fast threshold was changed on July 24 2015 due to low livetime. However, the change probably wasn't needed; the tohban hadn't noticed that a change had already been made a few days ago. The next tohban can reverse the change if desired.<br />
2015-205-17:18:59 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-205-17:19:08 /IDPLOAD VALUE=0x70 ; was 0x60<br />
<br />
* The rear fast threshold was changed on Sep 9 2015 due to low livetime.<br />
2015-252-17:51:10 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-252-17:51:17 /IDPLOAD VALUE=0x80 ; was 0x70<br />
<br />
* On October 8, 9, and 12, the rear fast threshold was raised three times to try and raise livetime. Results still need to be assessed.<br />
<br />
2015-281-21:50:13 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-281-21:50:24 /IDPLOAD VALUE=0xA0 ; was 0x90<br />
<br />
2015-282-19:55:48 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-282-19:55:58 /IDPLOAD VALUE=0xB0 ; was 0xA0<br />
<br />
2015-285-21:51:28 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-285-21:51:37 /IDPLOAD VALUE=0xC0 ; was 0xB0<br />
<br />
* Also on October 12, the front fast threshold on D1 (and also D7) was raised. This is to try and top off the livetime used in the attenuator logic. It might not work, since the fast rates are not terribly high for this detector, in which case the change could be reversed by a future tohban. Check this and see..<br />
<br />
2015-285-20:16:55 /IDPUTABLE1 OFFSET=FRONTFASTDAC<br />
2015-285-20:17:03 /IDPLOAD VALUE=0x50 ; was 0x40<br />
<br />
* On November 6, 7, 8. the rear fast threshold was raised three times to try and raise livetime. At 0xFF the live time is at 70%<br />
<br />
2015-312-06:16:29 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-312-06:16:52 /IDPLOAD VALUE=0xE0 ; was 0xD0<br />
<br />
2015-313-19:22:53 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-313-19:23:03 /IDPLOAD VALUE=0xF0 ; was 0xE0<br />
<br />
2015-314-18:55:49 /IDPUTABLE1 OFFSET=REARFASTDAC<br />
2015-314-18:56:05 /IDPLOAD VALUE=0xFF ; was 0xFF<br />
<br />
* 2015 December 14 lowered HV by 200 V in an attempt to reduce D1 rear, fast rates<br />
<br />
2015-348-18:19:00 /IHVDAC DETECTOR=1, VOLTAGE=176 ; 34-6.8 V<br />
<br />
* 2015 December 28 lowered HV by 200 V in an attempt to reduce D1 dead time<br />
<br />
2015-362-09:13:58 /ihvdac detector=1, voltage=166 ; Lowered G1 HV by 200V<br />
<br />
* 2016 January 13 lowered HV to 2500 V<br />
<br />
2016-013-21:20:47 /IHVDAC DETECTOR=1, VOLTAGE=129 ; 2500 V<br />
<br />
* 2016 January 27 lowered HV to 1500 V<br />
<br />
2016-027-20:16:13 /IHVDAC DETECTOR=1, VOLTAGE=77 ; 1500V from 2000V<br />
<br />
=== Post 2016 Anneal ===<br />
<br />
* 2016 April 27 (DOY 118): Started turning on D1. HV reached 3995 V by April 29, ~03:40<br />
<br />
16-119-00:49:49 start ihv_ramp_stage1_g1_g4_g7 (HV = 0x0A, ~200 V)<br />
16-119-02:27:48 start ihv_ramp_stage2_g1_g4_g7 (HV = 0x33, 980 V)<br />
16-119-04:08:00 start ihv_ramp_stage3_g1_g4_g7 (HV = 0x67, 1985 V)<br />
16-120-00:22:16 start ihv_ramp_stage4_g1_g4_g7 (HV = 0x9A, ~3000 V)<br />
16-120-02:01:36 start ihv_ramp_stage5_g1_g4_g7 (HV = 0xB3, ~3500 V)<br />
16-120-03:41:12 start ihv_ramp_stage6_g1_g4_g7 (HV = 0xCE, 3995 V)<br />
<br />
* 2016 June 27-28: Turned on D1 again. The final HV is 4000 V. The front and rear counts looked good. D1's front live time was around 98.6 % and the rear<br />
live time was about 97.8 % The last commanding was at DOY180-20:54 UTC. <br />

== Solar Activity ==<br />
<br />
The activity has been low throughout the week, mostly at B-level. There are currently 2 ARs on disk.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 25 13 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 12 8 0 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 11 5 0 0<br />
<br />
There were RHESSI flares/GOES flares 90 / 38<br />
over the time range 10-May-16 17-May-16<br />
<br />
<br />
There are issues with the process creating the RHESSI flare list for this week, and these issues will persist until the detector situation is stable, so the RHESSI flare count is an overestimate.<br />
<br />
== Memory Management ==<br />
<br />
Decimation was active/vigorous for the full time period. The SSR is empty after each day's passes, with a maximum of 11%. <br />
<br />
== Spacecraft Status ==<br />
<br />
Detectors 1, 3, 8 and 9 are powered on, and are recording events. The cold plates, 1 and 2 are at 136.0 and 134.7 K, respectively (They were 134.6 and 133.2 K last week).<br />

<br />
<br />
== Detector issues ==<br />
<br />
Detectors 1, 3, 8 and 9 are powered on, and are recording events. No excess large numbers of resets or fast or slow rates at present. Detector 2 was also powered up during the week, but did not segment at 5000V, so were turned off. Detector 4 is being turned on again today to see the thermal impact and to obtain more flare spectra to evaluate the low-energy performance (The D4 HV will reach 4000V at 11:50am, during the Ops meeting).<br />

<div>This page contains information about changes/issues for RHESSI detector 9 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 9 anneal 2012]]<br />
<br />
===Post 2014 Anneal===<br />
<br />
Detector 9 is SEGMENTED after the 2014 anneal!<br />
<br />
* 2014 August 20: Due to sporadic noise in D9, the HV was dropped by 20 counts (now at 3600V). Commanding was at 20:57 UTC. This successfully quieted the noise. The noise was mainly fast counts, which cut drastically into the livetime.<br />
<br />
* 2014 October 8: This detector has started to show some periodical spikes during last couple of days. Still is not clear what is their origin. It seems to be periodic with the orbit. So far no action taken.<br />
<br />
* 2014 Oct 31: Elevated noise during the period of Oct 31 - Nov 2. The onset, as well as the abatement was sudden. No commanding was done and the noise returned to regular levels.<br />
<br />
* On 2015 Jan 8, the rear fast threshold was raised since fast counts were eating up a lot of livetime.<br />
<br />
15-008-17:45:50 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-008-17:46:04 /IDPULOAD VALUE=0x50 ;(was 0x45)<br />
<br />
* Rear fast counts are high again, so we raised the rear fast threshold by 16 steps, in two sets of 8, on the BGS pass starting at ~3:30 PST. The new value is 0x60 (was 0x50). Fast rates as eyeballed from the realtime data were approx 58,000 (pre-adjustment), 12,000 (after 8 steps up), and 1600 (after 16 steps up). Livetime percentages were approx 60%, 90%, and 98%, respectively.<br />
<br />
15-021-23:33:58 /idpudumptabl table=dibtbl9<br />
15-021-23:34:03 /idputable9 offset=rearfastdac<br />
15-021-23:34:34 /idpuload value=0x58<br />
<br />
15-021-23:36:47 /idputable9 offset=rearfastdac<br />
15-021-23:36:55 /idpuload value=0x60<br />
<br />
* The rear fast threshold was raised again for the same reasons as the last two adjustments. The threshold was raised in two jumps of hex 8 each.<br />
15-057-18:43:13 /IDPUTABLE9 OFFSET=rearfastDAC<br />
15-057-18:45:14 /IDPLOAD VALUE=0x68<br />
<br />
15-057-20:21:52 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-057-20:22:09 /IDPLOAD VALUE=0x70<br />
<br />
* Rear fast threshold changed again, usual reason.<br />
15-064-19:39:50 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-064-19:40:12 /IDPLOAD VALUE=0x80 ; was 0x70<br />
<br />
* And again, on March 11, 2015.<br />
2015-070-22:46:04 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
2015-070-22:46:19 /IDPLOAD VALUE=0x90<br />
<br />
* On March 13, 2015 the rear fast threshold was changed again<br />
15-072-22:06:18 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-072-22:06:31 /IDPLOAD VALUE=0xA0<br />
<br />
* And then again, on March 16, 2015.<br />
15-075-19:24:13 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-075-19:24:28 /IDPLOAD VALUE=0xB0<br />
<br />
* And then again, on March 18, 2015.<br />
15-077-TBD /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-077-TBD /IDPLOAD VALUE=0xC0<br />
<br />
* And again, on March 25, 2015.<br />
15-084-21:07:00 /IDPUTABLE9 OFFSET=REARFASTDAC<br />
15-084-21:07:14 /IDPLOAD VALUE=0xFF<br />
<br />
* In addition we change the HV on March 25, 2015:<br />
15-084-19:26:07 /ihvdac detector=9, voltage=176<br />
15-084-19:27:17 /ihvdac detector=9, voltage=166<br />
15-084-19:28:33 /ihvdac detector=9, voltage=156<br />
15-084-21:05:17 /ihvdac detector=9, voltage=136 (2622 V)<br />
<br />
* As of early April, detector 9 rear segment is now essentially non functional. Rear fast rates have increased to the point where livetime dropped to zero, and the fast threshold is already turned all the way up so we have no way to control those rates. The front segment appears to be operating normally, though its fast AND slow rates are high (but not worringly so).<br />
<br />
* 2015 April 7: To deal with slightly reduced livetime in the FRONT segment, we changed the front fast threshold. This does NOT seem to have had an effect!!<br />
15-097-19:58:06 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
15-097-19:58:14 /IDPLOAD VALUE=0x30 ; was 0x22<br />
<br />
* 2015 April 14: We increase the Front Slow Threshold just to reduce the values on the front slow valid counts<br />
15-104-14:09:00 /IDPUTABLE9 OFFSET=FRONTSLOWDAC<br />
15-104-14:09:12 /IDPLOAD VALUE=0x1A<br />
<br />
* 2015 May 13: D9 front fast was increased <br />
2015-133-19:09:39 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
2015-133-19:09:52 /IDPLOAD VALUE=0x40 ; was 0x30<br />
<br />
* On June 11 2015 the front fast threshold was raised because the fast rates were high and the livetime was low. This action was DID reduce the fast rates but did NOT increase the livetime much! D9 now does not show high fast rates, slow rates, or resets, but yet the livetime is quite low.<br />
<br />
* On August 20 2015 the front fast threshold was raised in an attempt to gain livetime, which was at ~15%. This was unsuccessful.<br />
15-232-22:21:09 start idib_chg_thrshld (9, FRONT, FAST, 0x90)<br />
15-232-22:21:38 /IDPUDUMPTABL TABLE=DIBTBL9<br />
15-232-22:21:38 /IDPUTABLE9 OFFSET=FRONTFASTDAC<br />
15-232-22:21:46 /IDPLOAD VALUE=0x90<br />
<br />
* On August 20 2015 the rear segment started dumping a huge number of ULD events into the SSR, filling it. Once the problem was pinpointed, D9 events were disabled entirely on the 21st. D9 HV was turned down to 1800V, then 900V, then 800V, in an attempt to bring down the resets. This brought resets down from 30k to 23k and did, indeed, quiet the ULDs. The detector remained segmented. At one point the threshold change to D9 front was reversed to see if that had caused the problem (it hadn't); the threshold change was then re-implemented. Events were turned briefly back on on Aug. 24 and then off, although no danger signs were seen. As of Aug. 25, D9 events are still off. Approximate commanding times are below:<br />
August 21:<br />
1:15 pm PDT: D9 front fast threshold to 0x60 (was 0x90).<br />
2:50 pm PDT: D9 front and rear events disabled.<br />
4:30 pm PDT: HV drop of ~400V, performed in two steps, to 1838V. No change to resets (30k). RTS load to keep D9 events from being re-enabled after eclipse. D9 fast and slow thresholds to max.<br />
6:00 pm PDT: HV drop to ~900V and then again to ~800V. Rear resets before and after are 30k then 25.7k then 23.5k. D9 front fast threshold returned to 0x90.<br />
<br />
* On August 24 2015 D9 events were enabled at 20:42:45 UTC in order to check whether we would still dump too many events into the SSR. The write pointer speed didn't seem to change with this action (although it maybe did change with other detector threshold changes). We left D9 events on, knowing that they'd be turned off again at the next dawn due to the RTS load. As of Aug. 26, D9 events are still off.<br />
2015-236-20:42:45 /itmon value=AFE8 (Detector 9 events turn on)<br />
<br />
* On Sept 9-11, 2015, the rear D9 ULD rose, finally going crazy and maxing out on Sept 11. Since events were off, this wasn't noticed until Sept. 28. To try and avoid/mitigate potential damage to the detector, we lowered the HV on D9 on Sept. 29 PDT (Sept. 30 03:00 UTC) from ~800V to 490V. We briefly turned on events for G9 as well. Events were then turned off again at eclipse entry. The ULD event rate should be checked as soon as we get the monitor rate data on it. The detector stayed segmented.<br />
<br />
2015-273-03:00:43 /itmon value=AFE8 (Detector 9 events on)<br />
2015-273-03:01:09 /IHVDAC DETECTOR=9, VOLTAGE=26<br />
<br />
<br />
* D9 ULDs went haywire again, so we decided to turn off the HV and electronics for D9. On Oct 13 Jeremy removed all power from detector 9's HV and turned off DIB (Detector Interface Board) 9. This commanding was done October 13, 2015 at 18:22 UTC. It should be monitored to see if we get any noticeable changes to power or temperature diagnostics due to this.<br />
<br />
2015-286-18:21:43 /IHVDAC DETECTOR=9, VOLTAGE=0<br />
2015-286-18:22:48 start idib_single_off(9)<br />
<br />
===Post 2016 Anneal===<br />
<br />
* D9 HV ramped up to 4000 V. The detector was segmented around 1700 V. We adjusted the rear fast threshold up from 0x45 to 0x60 then turned on events. <br />

<div>This page contains information about changes/issues for RHESSI detector 2 after the 2014 anneal. Detector updates from 2012-mid 2014 can be found here: [[Detector 2 anneal 2012]]<br />
<br />
===Notes===<br />
<br />
Detector 2 is UNSEGMENTED (no surprise there) following the 2014 anneal.<br />
<br />
* 2014-Aug-21 Due to noise in D2, the HV was lowered by 20 counts to 4117V at 2014-233-20:41:14 UT. This was successful in quieting the noise.<br />
<br />
* 2014-Aug-26: D2 is suffering a lot from the known light leak problem. This does not affect the quality of the data but greatly reduces livetime at times when light leaks in through the cryostat port. To alleviate this problem, the G2 front fast threshold was raised from 0x30 to 0x38 at 2014-238-19:22:56 UTC. This didn't seem to fix the problem.<br />
<br />

2015-152-17:01:16 /IDPLOAD VALUE=0x70 ; was 0x58<br />
<br />
* 2015-Dec 9: D2 Front-fast threshold was raised from 0x70 to 0xFF in an attempt to reduce noise. As a result, the fast rates went down and D2 spectrum also showed reduced noise. The spectrum now looks typical as an unsegmented detector. We can't see the flare spectrum, but the slow threshold is set high enough that we wouldn't expect to see it. We'll have to wait for a bigger flare to see if D2 is returning good flare data, but I don't see evidence of bad behavior.<br />

<br />
===Post 2016 Anneal===<br />
<br />
* 2016-May-12: D2 HV was ramped to 5000 V over the course of 4 orbits. Along the way we increased the slow and fast front thresholds. It did not show signs of segmentation. We then turned down the HV and turned off the DIB.<br />

== Solar Activity ==<br />
<br />
The activity has been low throughout the week, mostly at B-level. There are currently 5 ARs on disk and 3 of them are expected to rotate off the disk in the next day or so.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 25 11 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 11 6 0 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 10 3 0 0<br />
<br />
There were RHESSI flares/GOES flares 69 / 36<br />
over the time range 09-May-16 16-May-16<br />
<br />
<br />
There are issues with the process creating the RHESSI flare list for this week, and these issues will persist until the detector situation is stable, so the RHESSI flare count is an overestimate.<br />
<br />
== Memory Management ==<br />
<br />
Decimation was active/vigorous for the full time period. The SSR is empty after each day's passes, and is at 0.4% currently (2016-05-17 22:40).<br />
<br />
== Spacecraft Status ==<br />
<br />
Detectors 1, 3, 8 and 9 are powered on, and are recording events. The cold plates, 1 and 2 are at 136.0 and 134.7 K, respectively (They were 134.6 and 133.2 K last week).<br />
<br />
== Data Gaps ==<br />
<br />
No significant (>300 sec) data gap.<br />
<br />
<br />
== Detector issues ==<br />
<br />
Detectors 1, 3, 8 and 9 are powered on, and are recording events. No excess large numbers of resets or fast or slow rates at present. Detector 2 was also powered up during the week, but did not segment at 5000V, so were turned off. <br />
