    keyword=Day shift summary

    8:10 - NMR measurement. Target polarization: 56.1%

    8:20 - High voltages on bar crates are coming up fine.

    8:45 - Start run 3620. Raster is 2x2 but not really square, maybe due to changes in beam position by MCC at the beginning of the run.
    HV fell again. The run was stopped at 9:02.

    9:20 - Controlled access to the hall for changing a high voltage crate.

    11:30 - Starting cosmics run 3621. I set the thresholds on the BB for a cosmic run: PS(1): -10mV, SH(2): -25mV. End: 12:20, with ~120000 events.

    Taking NMR, EPR, NMR measurements.

    12:40 - Asked for beam.

    12:45-13:00 - Run 3623. Run was stopped because of alarm about genps2:2002 HVs. Brandon raised the HVs .

    13:07 - Start run 3624.
    13:20 - Start HAPPEX run 7211.
    ~13:40 - Start Compton - looks BAD.

    13:52 - Stop run 3624 due to another alarm about genps2:2002. There was a spike in T2 on ~13:50.

    13:53-14:18 - Run 3625. Run was stopped to let the tunning of Compton measuring system.

    Empty target was put in instead of He3 target, for the tunning.

    15:30 He3 target is inserted
