Detector 9 anneal 2012

From RHESSI Wiki

Jump to: navigation, search



Some "historical record searching" has revealed that noisy intervals have occasionally shown up in D9 ever since the March 2010 anomaly. It is not clear that these were associated in any way with the anomaly, but no instances have been found before it. These noisy intervals are easiest to see in the rear slow monitor rates or rear event rates. See a presentation (2013-04-17_Detector_9_weirdness) by Albert Shih for more info.

No action was taken since the problem was not severe. See more notes in the Tohban_Report_2013-05-08 tohban report.

 They began in short and non-severe dropouts on the 4th. By the 9th, their duration and severity increased to a maximum before beginning to
 wane again on the 10th. 

No action was taken since their severity and frequency was comparable to those seen in the past, and there were no consequences to livetime or SSR.
