    keyword=Swing shift Summary

    4:00pm Continue taking data on HRS-L at 2.4918 GeV/c and HRS-R at 2.0696 GeV/c
    4:10pm Per Hovhannes's request, increase beam current from 80nA to 100nA.
    4:30pm Beam Energy was shifting +-2MeV during the last three hours and caused the beam positions changed and hit the beam pipe, since MCC was bringing up Hall-C. Beam Energy stablized after Hall-C back.
    4:55pm 1HWP out
    5:20pm Control Access requested to change Target MicroWave
    5:30pm Back to Beam Permit and start polarizing target
    6:20pm Target Polarized. Taking data
    8:45pm HRS-L changed to 2.6508GeV/c
    9:10pm 3rd Arm HVs off. Chao turned them back on
    11:40pm HRS-R finished data taking at 2.0696. Change Momentum to 1.9454. James works on target aneal. Pengjia works on BCM calibration
    12:00 All activities above on going.
