Notes
Notable issues since 2012 anneal:
- 2013 March 25: Detector 5 arced and then had an extended interval of high rates, which went on for about 1.5 hours before it quieted itself. The data from the noisy period was all at low energies. This is similar to a November 2011 anomaly that happened the same way, although that event did not quiet on its own. (Note that event was before the anneal.) In this case, no corrective action was taken at the time, although the HV will be dropped slightly in the near future. See Tohban Report 2013-03-27 for a more thorough description and plots illustrating the problem. LG
- 2014 May 27: G5 front fast threshold was changed to 0x30.
