keyword=prex quartz det work, part II
KK replaced the PMT on the quartz detector. Put it back in place
and the rate was noticeably lower, perhaps 5 Hz. There is now a
clear overlap between the Quartz and PREX-scint (again, the Quartz
is located just under the scint and is upside-down-and-tilted in
such a way as to catch cosmics.) Now we do a long run 4326 with
ps2 = 1 and ps3 = 1. T2 rate is 40 Hz and T3 rate is 2.7 Hz.
Will look for pulse-height distribution shortly.
