    Shift Summary

    16:00 Shift starts at the end of beam study, Hall is ready for beam tuning.
    16:22 Target moved to EMPTY for beam tuning.
    18:00 Beam tuning done, start BCM calibration.
    19:25 BCM calibration done, move target to BeO for raster check.
    19:35 Raster is set to 3x3(4.5x3 MCC value), move to 3He for production.
    20:00 Start production with 120 μA beam since run 4112.
    23:10 Finished 29.5k 3He events (1/3 of planned), moved to 5 mm C per RC's request.
    23:10 Beam is off due to MCC IOC problem.
    24:00 Still waiting for beam.
