    keyword=Shift Summary

    8:00 Shift started.
    Access to Hall to reset Q2 on the right spectrometer.
    Q2 triped in the last hour of the owl shift.

    Second access to Hall to reset Q2 which dropped down to
    zero when it was settling to its nominal momentum value.

    9:50 Start the rates vs position study.
    Because the current we are using is around 0.4uA
    FFB not operational.

    Rates vs Y position in BPMB
    BPMB (x,y) Run # BPMA (reading)

    (-1.4,0) 2232 (1.7,0.5)
    (-1.4,+1) 2233 (1.7,0.5)
    Restart after a long stop at 15:35.
    (-1.4,0) 2234 (1.7,0.3)
    (-1.3,+4) 2235 (1.5,0.9)
    (-1.4,-2) 2236 (1.5,0.1)
    Day shift ended
    (-1.4,-1.1) 2237 (1.6,0.8)
    (-1.4,+1.0) 2238 (1.55,0.8)
    (-1.4,+1.9) 2239 (1.57,0.07)
    (-1.4,2.8) 2240 (1.5,0.05)

    10:25 Problem with BPMB readout
    10:35 Beam gone due to Hall A laser lost lock.

    13:05 Laser lock fixed, but vaccuum problem in the north linac.
    13:35 Vaccum in north linac still a problem
    14:10 Controlled access for some Compton work (baseline restorer switch out).
    14:20 Power Permit
    15:15 Beam back. Continuing the rates vs position studies.

    Shift ended in the middle of the test.
