Polarized Deuterium. Smooth running all shift. Runs: 1187-1192
1194-1195 (~2M events)
mostly smooth running, just the usual trips etc:
Compton: rebooted VME 4 times
CODA: 1 restart
HV GUI
WCh: fine for most of the shift. slot 1 ch. 7 in WCleft crate started
tripping every minute. changed HV to 3700 V and it was fine for about 1
hr, then started tripping again. turned it down to 3600 V and so far so
good. Right Wch crate tripped a few times, but nothing major.
CC: one of the Cerenkov channels kept tripping in the right crate (slot
6 channel 8, corresponding to right C #1, bottom #2). Tavi determined
it was a bad channel and reconnected the tube to slot 6, ch 5 (which was
empty) set this channel to -2152 V and zeroed 6/8. now the crate
doesn't trip.
all runs up to 1195 have been charge.C'd and lrn'd (some are still
crunching) and runs up to 1190 have been flrn'd.
