    Summary

    00:00 Shift starts, positioning beam and target.

    00:30 No beam, MCC working on one of the cavities to make the energy stable.

    01:20 Beam back, waiting it stablized.

    02:10 Beam energy stable in a good position.
              Position locked, move on to production.
              Target polarization in process.

    02:45 Starts production, TO optimizing the target polarization, 40% now.

    05:50 There has been no beam for 20 minutes. Now comes back.

    07:20 HWP Flip from IN to OUT. For 1.0171 GeV, we've reach the number we need. But,

    08:00 Two more hours will be spent for this kinematics due to late HWP flip.
              Over.
