UPDATE IN PROGRESS
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
Notes
Detector 3 is SEGMENTED following the 2014 anneal (yay!)
- 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.
- Another threshold change b/c of light leak:
14-241-18:34:11 /IDPUTABLE3 REARFASTDAC ;Load address 0x25CC 14-241-18:34:31 /IDPULOAD VALUE=0x60 ;Rear fast from ox50 to 0x60
