    keyword=owl shift summary

    Shift crew: R. Michaels, G. Kumbartzki, A. Camsonne

    At start of shift we inherited the last run of kinematics 4.4

    Runs:
    Left-arm........Right-arm.......HAPPEX.............Comments

    20288..............1288...............1247.....................kinematics 4.4
    .........................................................beam half wave IN, target pol 0 degr.

    Changed momentum to P = 2.35 GeV/c (kinematics 4.5)
    --> R-arm dipole trips. We could not stop its fall.
    We skipped Carbon/Ref-cell runs, thinking we'd do them when R-arm recovers.

    20289...............1289...............1248.......R-arm data is junk (except scalers)
    ...............................................................beam half wave IN, target pol 0 degr.
    20290...............1290...............1249.......same
    20291...............1291...............1250.......same

    Have 150 K good events for the above setting.
    Now switch to target pol 270. Beam half wave remains IN. Kine 4.5.6

    20292...............1292...............1251.......tgt pol 270, beam wave IN. R-arm still junk
    20293...............1293.............none (forgot).......same
    Although we forgot to run HAPPEX DAQ during *293, Qasy was only 30 ppm.
    Qasy does not drift much.

    20294...............1294...............1252.......same..... in progress at end of shift.

    Problem: R-arm dipole does not want to exceed 790 Amps.
