    Entry number 167608

    keyword=day shift summary

    0800: status at shift start -- Compton running, at least temporarily. Production on 3He at 7 uA. BPMB x=-3.07, y=-0.44. Beam spread on SLI about 9.2e-5.

    0825: start 3194. Abort at 0905 due to hung ROC3.
    0920: start 3195
    0943: MCC takes beam away for "few minutes". They will do some injector tests. In the meantime, we start NMR measurement. Stopped Compton and Happex.
    1000: NMR = 40.8%. Beam still off for injector tests.
    1035: beam back, IHWP IN
    1045: had some difficulty getting beam centered again. Now back to x=-3.09,y=-0.44. Start run 3197. Also start Happex run 7100. Sirish is working on Compton.
    1230: Sirish and Xiaochao got Compton going again and analyzed the most recent (only 7 minutes). We now have a beam polarization about 87 +/- 6. Everything seems to be working but background pretty high.
    1320: CODA hung. Need to stagger ROC reboots.
    1340: A successful Compton restart!
    1430: At the beginning of run 3201, we asked MCC to reduce background in Compton, reduce energy spread, keep beam position on target same. Will attempt to take data while they tune.
    1505: genps2:2002 tripped during harp. Attempted to reset during run 3202, but lost communication. Finally reset, abort 3202.
