    keyword=Shift Summary

    16:00 continue taking data in 5H, until charge is 0.6C
    17:20 change program discontinue 5H and move to 5G with two extra settings.
    17:25 request controlled access.
    17:40 Hall on controlled access, Magnet off
    18:07 moved spectrometer and calorimeter to 5G(f/g) positions, request beam
    18:10 moved to Optics target for optics run
    18:14 got beam permit
    18:46 moving target to LH2 no radiator
    19:24 ROC14 not responsive, rebooted it and restarted coda
    19:50 Requested controlled access for position change to 5G(f+/g+)
    19:53 Hall in controlled access, moving target to optics target
    20:25 Moved Calorimeter and spectrometer to 5G(f+/g+) position
    20:25 Fire alarm in Hall B waiting for MCC to finish checking it out
    20:35 Fire alarm was false, got beam permit
    20:41 FSD Trip
    20:42 Got beam
    20:51 moving target to LH2 no radiator
    21:35 FSD Trip (RF Trip)
    21:45 Got Beam Back
    22:05 Requested controlled access for position change to 5G(f-/g-)
    22:10 Waiting for Hall B to finish Moller run
    22:22 Beam down, Hall in controlled access
    22:40 Moved Calorimeter and Spectrometer to 5G(f-/g-) position, moved target to optics
    22:40 Beam in FSD Trip
    22:47 Hall on Beam Permit
    22:59 Got Beam
    23:09 BPMB Y position was 1.714 (instead of 1.5), corrected with MCC
    23:15 moving target to LH2 no radiator
    23:13 FSD Trip (RF Trip) MCC experts on site to examine problem
