    keyword=Shift Summary

    Continue production data taking at 3.46 GeV, p=1.6 GeV/c, theta=18.60 deg, transverse polarization (270 deg), both half-wave plates out.

    8:00-9:30 Continuing data taking, runs 2760-2762/21760-21762.
    9:30- 11:30 Attempt eP, no success, too much background, bad tune.
    11:30 NMR/EPR. Target to 0 degrees. Leaving target at 0 degrees after NMR/EPR to be able tp pump for a while while calibrations are going on.
    12:00 Calibrate half-wave plate slope for half-wave plate out.
    13:15 Calibration done. Change target direction back to to 270deg in preparation for production running.
    13:22 Start production runs 2773/21773. (Runs *63-*72 are empty target/BeO/calibration runs, see runsheets & halog.)
    14:02 NMR.
    14:26 Back to production running, runs 2774/21774.
    14:30 Unstable beam for a few minutes.
    15:15 Accelerator loses RF zone, down for some 10 minutes.
    15:25 Decide that we have enough data at this setting. Rotating the target spin to 90 deg. Target half-wave plate in. Last run of these kinematics is 2775/21775.
    16:00 Still waiting for beam.
