    keyword=Shift Summary

    -Shift crew: SL: F. Benmokhtar, TO: Huan Yao, 3rd: Xinhu Yan
    -----------

    - Running kin K, P0 = 1.51 GeV, beam Energy: 5891.95,
    beam current = 15uA.
    - 1:30 Lecroy HV alarm went off, slot 11, channel 1 in
    the beamline HV was OFF, turned it ON
    - 3:39 MCC took beam to improve the quality.
    - 3:57 Beam is back, restarted all the DAQs including the Beam ones.
    Still so many beam trips
    - 4:55 S14 and S15 HV Bigbite HV trips.
    - Better beam quality.
    - 6:35 Vince called in and asked us to move to the new kinematics.
    Started moving the target, set P0 to 1.34 GeV.
    - 6:45 Taking a 1/2h N2 run at 5uA with both Bigbite and LHRS.
    - 7:15 Moving to 3He production, at 15 uA
    - 7:22 Started production running.


    -Bigbite runs:
    --------------
    1886 so many beam trips
    1887 // //
    1888 // //
    1889 ended, MCC took beam to improve the quality
    1890
    1891 Stopped, Bigbite HV S14 and S15 trips.
    1892
    1893 Ended to change kineamtics.

    -Here starts Kin =I, P0 = 1.34 GeV
    ---------------------------------
    1894 N2 run at 5 uA
    1895 3He production at 15 uA


    -LHRS runs:
    ---------
    Total Charge was 1.003 Coulomb after run 20444.

    20445 0.09130C --- Many beam trips
    20446 0.00099C --- Many beam trips
    20447 0.03220C --- Ended, MCC took the beam to improve it.
    20448 0.09720C ---
    20449 0.006 --- Ended, Vince thinks we have the total
    change we want for this kinematics.

    Total charge at this kinematics: ~1.24 C

    -Here starts Kin = I, P0 =1.34:
    ------------------------------
    20450 N2 run at 5 uA.
    20451 3He production with 15 uA.
