    keyword=shift activity, swing March 3rd.

    16:00 start shift, waiting for one pass beam.
    17:50, beam ready.
    put in c12 target for check out.
    17:53 c12 test run, beam position is changing
    17:57 beam off. due to injector work.
    18:22 beam back. Joe Mitchell preparing for e-p.
    18:30 did harp scan run-560, with raster off. check with spot.
    MCC check beam lose, indicating raster problem, take c12 target out for check .
    18:55 c12 in beam again
    19:20 set raster size. 4.0 by 4.0 mm by spot ( asked MCC 1.5 by 5.0)
    take harp scan run562
    19:30 start run 2528, he-3 elastic in e-arm, 5uA beam.
    prescal factor 1,1,1,10,1
    raw scaler rate 1.7K, 88, 180,134,0.
    dead time 21%
    check OTR reading , saved in halog.
    Found that OTR was not with proper mask.
    20:00 e-p measurement
    21:00-22:00 harp many scan, to make sure beam spot size
    is less than 200um in both x and y.
    22:00 Mcc cycle the qurds in hall-A line after beam tuning.
