    Swing Shift Crew:
    V. Sulkosky (SL), J. Huang (TO)

    Summary
    =======
    16:00 Start shift in Controlled Access to swap VME to fastbus.
    17:30 MWDC 1 HVs tripped off, re-enabled.
    17:35 MWDC 1 HVs tripped off again. Problem related to the balloon
    pressing up against the first chamber.
    19:35 Work completed in the Hall. Asked for Beam Permit.
    19:50 MCC getting ready to deliver beam to Hall A. Raster off.
    19:56 MWDC 2 HV tripped.
    20:04 MWDC 2 HV restored.
    21:04 Beam back to Hall, perform Harp scan: widths < 200 um for 1H03A and 3B.
    21:12 Move to Carbon with Hole target to check beam position and raster.
    Raster size increased to 4.5 mm x 3.0 mm at MCC.
    21:37 Move to BeO target.
    21:41 Target in place, 5 uA on BeO. It appears the camera light has been moved.21:43 Move to Carbon with Hole target.
    21:45 Asked for Controlled Access to reboot Fastbus for BigBite.
    22:23 Hall in Power Permit.
    22:28 Hall in Beam Permit.
    23:27 Move to Loop 1 LH2 target.
    23:34 Ask for 1 uA beam and raster size 1.5 mm x 1.0 mm at MCC.
    23:34-24:00 BigBite HV for dE and E plane tripped off related to
    bad beam position.
