Beam conditions very good OTR out. Best I have ever seen.Took pedestal run 220 and began a 20000 event run to look at what we seeunder these conditions. Run number is 517
Adjusted voltages on PMT to give no saturation. AG1 and CsI SLAC give no apparent signal under any voltage range. Either they are in low background region or they are dead. Will test this later with OTR in.Voltage settings
C1 900
c2 1201
ag1 1500
ag2 0
c6 1600
c7 1350
c10 0
CsISLAC 700
CsIDESY 700
c15 0
c16 0
There are no attenuators. Run type-simple
As example GCALOLD sees about 75 counts or about 50 GeV
Put OTR in and readjust voltages
C1 800
C2 1100
ag1 1500
ag2 0

CsISLAC 800. See a signal here but does not change with voltage
CsIDESY 525
