    keyword=Shift Summary

    16:00 shift start
    17:00 Javier and Jack still down in the Hall dealing with the Q3 magnet issue
    18:30 Hall in beam permit
    19:00 J. Benesch called and said he could get 300 microns x 300 microns beam. Getting better would require a couple of hours.
    We are accepting the beam which is in the upper limit of our specs
    19:04 MCC start setting up Hall A line
    19:15 Beam is delivered on Be0 target (8 microA)
    Beam spot runs on BeO: 4217,4218
    20:00 Checking alignment and Raster size (Alex and Nikos)
    Beam spot runs on Carbon hole: runs 4221 to 4229
    21:20 Quasielastic run #4230 to 4232
    21:30 Asked for controlled access
    22:00 Ed and Jack down in the Hall to spectrometers angles.
    22:10 Quads and dipoles cycled to get to the new momentum values
    HV on Hadron/Right S1 set to 72% of nminal max
    trigger downloaded (E'=527.9, Pr=1.217)
    22:55 Jack and Ed back. Asked for beam to start production runs.
    23:20 Jay Benesh asked to move the position of the beam by 1 mm to
    be able to raise the current from 70microA to 101microA
    the values of BPMs are:

    BPMA x = -2.95 y= 1.6
    BPMB x = -3.00 y= 1.5

    23:40 Production run Elastic-3He
    # 4234 #events= 0.42M
    # 4235 #events= 225K
    # 4236 #events= still going
    24:00 End of shift
