    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

    There are no attenuators. Run type-simple
    As example GCALOLD sees about 75 counts or about 50 GeV

    Put OTR in and readjust voltages

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