    keyword=Swing shift summary

    Fairly smooth shift. Took a few 1-hour production runs, did some tests with the Ref(empty) and H2 targets [including one with bigbite at 300A]. One target polarization measurement (polarization has gone down ~2% since last measurement).

    Lost 30 minutes because MCC software that locks the current had a problem and set our current to zero. MCC didn't notice, we didn't realize that MCC didn't know there was a problem.

    Details below:

    ---- Production running ----
    2905 Production, 3M events

    ---- Tests on Ref. cell (vaccuum) ----
    2906 Ref(vaccuum), ~2x2mm raster (real), 1M events
    2907 Ref(vaccuum), ~4x4mm raster (real), 1.2M events

    ---- Hydrogen data (tracking+shower calibration) ----
    2908 Ref(H2)@131psig, 0.5M events (beam off for 30min in middle)
    2909 Ref(H2)@131psig, 2.0M events

    2910 Ref(H2)@131psig, 3M events, BIGBITE SET TO 300 Amps.

    2911 Production, 3M events

    NMR measurement at ~10:20pm gave 38.9%

    2912 Production, 3M events
    2913 Production, in progres...
