    keyword=Shif Summary

    17:29: Beam is down due to a magnet problem. MCC predicted a few min of beam down. -> we kept running coda (run 20/1452)
    18:09 Beam is still not back so we stop the run. 40 last minutes are junks
    18:18. Beam is back
    21:23 We asked for beam to be shut down in order to do target polarimetry. Then we will do empty cell run and N2 run.
    Pol_target=35.0%
    21:55 Start reference cell empty cell run (run 20/1435). 5 uA
    22:12 Stop empty run (we ran a little longer than 15 min because the beam was down
    a little bit)
    Fill the ref with N2. Start run Pressure: 145 psig
    end pressure:128 psig
    Pressure went up to 147 psig in the middle of the run (heat load effect ?)
    We ran at 12 uA
    Beam position was off position at the beginning of the run: BPMA_x=-0.5 BPMA_y=-1.6, PMB_x=-0.8 BPMB_y=-1.6.
    The 48K events (left HRS) were taken in this position.
    Then x=+1 AND Y=-2
    22:47 Stop ref cell run (20/1436)
    Back to kinematics 5.1.5.
