    July 23 day shift 8:00-16:00 summary:
    Shift works: W. Korsch, G. Urciuoli, J. P. Chen

    Shift started with running

    7:18-9:05 Run 2201/21201 production at x=0.48.
    Right arm (21201) DAQ problem, could not ENDRUN, no datamon. Seems
    scaler not reading. Had to stop coda to end run. Rebooted right arm.

    9:05 beam off for configuration change.
    We started pulser runs and access to hall for helicity study.
    Sync cable disconnected.

    Run 2202-2207 4kHz pulser run (PS1=1). First in toggle mode (2202-2205?).
    Then in random mode (2206 and 2207).
    Run 21202-21206 were runs for helicity test: First run test electronics,
    2nd 1MHz test scalers gated with LeCroy GG and 3rd with Philips
    (both in random mode). Then a run to test trigger 3 (4kHz trigger) (PS3=1).
    which was initially not plugged in properly, then
    plugged in fine. Then a reasonably long pulser run (still random mode).

    NMR/EPR before beam back.
    Beam back at around 14:00.
    Checked BeO, turned on raster, got toggle mode back, reconnected
    sync cable.
    Run 2208/21207 short run, still had ps fcator set for pulser run.
    Run 21208 junk run to get run number in sync
    Run 2209/21209 not long run, beam unstable. Stopped for hall c tuning.
    14:55 Beam off for Hall C beam tuning (RF separation).
    15:30 Back briefly then off again for tuning Hall C.
    16:00 Beam is back.
