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.

• Late August / early September. 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.
