    keyword=Owl Shift Summary

    Shift workers:
    Vincent Sulkosky, Jing Yuan, Luigi Lagamba, Jaideep Singh

    00:00 Start shift with 3He pressure curve at 35 psig in Reference cell
    00:07 Increase 3He in Reference cell to 90 psig, Run # 2436 has wrong prescale factor
    00:25 Called MCC, since there is a storm. They are trying to restore beam, but there are no guarantees. 104625
    00:40 Beam back at least for now
    00:55 Increase 3He in Reference cell to 139 psig, Run # 2438 is a short run with little beam.
    01:30 While waiting for beam, the field was rotated to 180 degrees to prepare for elastic data taking at 180 deg. and IHWP IN
    01:43 Finish 3He pressure curve, prepare for NMR and EPR measurements
    02:15 Bleedthrough measurement: 1.21%
    02:18 Start elastic Polarized 3He data taking at 180 degs. with IHWP IN
    04:04 Ask to have IHWP removed.
    04:07 Start elastic Polarized 3He data taking at 180 degs. with IHWP Out
    05:50 Noticed Raster size was off in X (1.5 by 2.5 )mm
    06:28 QE Measurement
    06:50 Raster finally 2.5x2.5 mm
    07:00 Ask for 10 uA of beam on Polarized 3He target
    07:29 Finished 3He elastic data taking
    07:40 Continue N2 pressure curve
    07:51 Increase Reference N2 pressure to 90 psig, Run # 2466 Prescale factor too low and end of run failed. kCoda and restart runcontrol. R-DAQ fine.
