    keyword=Owl Shift Summary

    Shift workers:
    Chao Gu(SL), Melissa Cummings(TO), Jechiel Lichtenstadt(3rd)

    00:00 Shift starts. We are taking production data at 2.2279GeV with LHRS, 1.1040GeV with RHRS.
    01:30 Move LHRS to 1.1040GeV. Take 2M data.
    02:00 Move LHRS to 1.0157GeV. Take 2M data.
    02:10 RHRS also settled at 1.0157GeV. The polarization is low because we increase the current to 100nA based on the request of RC. However we can still take some data with this setting.
    02:30 Move LHRS to 0.9190GeV. Take 2M data.
    03:25 Cycle LHRS back to 1.1040GeV and take dilution data at this setting.
    03:55 IHWP is flipped to OUT by Hall C.
    03:55 LHRS to 1.0157GeV and do dilution runs.
    04:25 LHRS to 0.9190GeV and do dilution runs.
    04:55 Start to polarize the BOTTOM cell.
    06:00 Polarized the BOTTOM cell to 65%, talk with RC, he suggests we start to take data.
    07:30 Start to do TE.
    08:00 Shift ends. Target group people is doing TE. After that, we will go to restricted access.
