    keyword=Day shift summary

    Day shift summary:
    Shift workers: J. P. Chen (SL/TO), R. Lindgren (3rd).

    8:00 taking production data at 3 pass.
    E=3606 MeV, P(both L &R)=3065.5 MeV. Angle=17 degree.
    BCMs still jumping (problem known from previous shift).

    Runs taken with L buffer mode, T3/T4/T8
    R un-buffer mode, T1/T8. T2 prescaled away.
    Two runs (20876,20877) with Right P2 set to 1 to take T2 as well.
    10:45-11:00 Yi/Alexandre do a test with Compton off to see if
    this is related to the BCM problem (result: probably not?).
    11:00 Left Coda begin run failed due to ROC5 not responding.
    Rebooted ROC5 and restarted coda, all are fine.
    Run 1956/1957 not exist.

    12:00 pass change starts (3 --> 2 pass) Hall in controlled access.
    Hall Controlled access activities:
    1) Bo/Vince, ROC8 busy problem.
    2) Ramesh/Xiaochao, PVDIS DAQ.
    3) Doug, BPMs.

    1:30 all out of hall. 1:45 pm beam permit.
    2:30 beam back.
    position
    harp scan,
    BeO check
    Raster check still gonig on at the end of shift.

    All runs afterwards are for raster checks.
