    Shift Summary

    16:00 Shift starts in the middle of run 4151 with BeO target.
    16:15 Target moved to 5 mm C.
    16:40 Target moved to 20 cm 3He, MCC took beam away for some invasive test.
    17:15 Beam is back, now 120 μA on 3He target. Continue production.
    20:00 Accumulated 962k good events on 3He, now move to 5 mm C with 120 μA.
    20:35 Accumulated 990k good events on C, now move to 40Ca with 40 μA and 4x4 raster.
    22:00 Accumulated 915k good events on 40Ca, now move to 48Ca with 40 μA.
    23:30 Accumulated 940k good events on 48Ca, now move to 20 cm dummy target with 40 μA and 3x3 raster.
    23:50 MCC took beam away for Hall C beam delivery.
    24:00 Still waiting for beam.
