Detector 8 anneal 2012
From RHESSI Wiki
- Week 28 Mar - 4 Apr 2012: Detector 8 is showing elevated front slow rates coming out of the SAA.
- 22 May 2012: The HV on detector 8 was lowered by 5 steps at 15:59:51 UT, bringing the HV down to 3921.6 V, due to an increased count rate coming out of the SAA. The effect was particularly noticeable in the front slow and livetime monitor rates.
- 23 May 2012: Detector 8's HV was lowered by 8 additional counts at 23:58:05 UT to remedy the high count rates seen in previous days. The voltage is now at 193 counts, 3750V. The high count rates in Detector 8 improved.
- There was a spike in detector 8 on 2012 June 29: [1]
- Week 4 - 11 July 2012: Detector 8 is started to look a little noisy coming out of the SAA.
- Due to an excess of low energy counts coming out of the SAA, the HV on detector 8 was lowered by 5 steps, from 193 to 188 on July 24, 20:25 UT. This reduced, but did not eliminate, the excessive counts. Since the noisy count rates were not so high that memory fill or livetime were compromised, no further voltage reductions were taken at this time.
