    keyword=Swing Shift Summary

    Shift Workers:
    Chao Gu(SL), Yuxiang Zhao(TO), Johan Sjoegren(3rd)

    16:00 Shift start, Kalyan is doing some beam position check
    16:35 Beam position check finished, go on to production, HRS momentum setting to 1550Mev, septa current to 488/539.5A, We are using the bottom NH3 target, the polarization is about 28.5%
    17:30 Beam is still not stable
    18:00 Target experts came to do the target anneal
    20:35 Target experts finished their work, we move back to production
    21:10 Finished production on 1550MeV, start to move HRS setting to 1441MeV
    21:50 RHRS is settled, so we start to do the dilution test
    22:35 Finished dilution runs, we will move the target to TOP NH3 target and polarize it
    23:00 Move on to production
    23:30 Kalyan suggest to decrease the slow raster size to avoid the extremely high rate on 3rd arm (it looks like the beam is hitting something). Move the raster size to 1.8cm and do a test on 3rd arm. Rate looks good. So Kalyan decide we should keep this setting.
    24:00 Keep production
