UPDATE IN PROGRESS
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
Notes
Detector 2 is UNSEGMENTED (no surprise there) following the 2014 anneal.
- 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 successfully in quieting the noise.
- 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.
G3 rear fast was rasied from 0x45 to 0x50
- Late August / early September.
