    keyword=Swing Shift summary

    16:00 Start shift with no beam. Right Q2 recovering from "quench".
    19:45 Tune beam arrives. Tuning Compton background, not very successfully.
    21:00 Compton tuning ends. Setting up for production.
    21:40 Harp scan results available, indicate a poor tune with converging beam.
    22:00 Starting Happex production with lH2. Run 12392.
    22:20 After discussing the beam quality, we decide to ask MCC to improve the intrinsic beam size. The concern is over a possibly dangerously small spot at the target.
    22:45 MCC has retuned the beam. Spot size now larger. Doing spot++ run on hydogen.
    23:00 We notice the beam position is slightly off and ask MCC to move the beam in Y by -0.5mm.
    23:30 Beam finally returns. Resuming Happex production. Run 12393.
    00:00 Data taking in progress at end of shift.
