    keyword=Shift Summary

    00:00 Shift Leader Vince Sulkosky, TO Jing Yuan, 3rd Luigi Lagamba
    Continue taking Production data at 2.005 GeV/c at 270 deg. and IHWP IN

    01:28 Finish Kinematic 5.10. Change R-Arm momentum to 1.871 GeV/c and Septum read back current to 173.25 Amps.
    01:50-01:55 NMR-EPR Measurements
    02:02 R-HRS momentum set and target moved to empty reference cell

    02:03 Asked for 10uA of rastered beam
    02:20 Asked for 2uA of rastered beam
    02:32 Fill Reference cell with 140 psig of N2
    03:00 Asked for Bleedthrough measurement, 4 measurements gave 0%
    03:13 Begin Polarized data taking at 0 deg. IHWP IN

    05:02 All three DAQ's failed to start after run #'s 2529/22529/3419.
    05:10 IHWP moved OUT
    05:15 Begin data taking at 0 deg. IHWP OUT
    05:23 Right and Left DAQ's working but Parity is not. Communication problem
    with ROC 23. Called Parity expert for assistance.
    05:47 I rebooted ROC 23 from the components window and the HAPPEX DAQ is now working. Parity run 4322 was running for 3 minutes during R/L runs 2534/22534.

    07:01 Finish 0 deg. IHWP OUT Configuration
    07:10 NMR and rotate to 180 degrees
    07:21 Begin 180 deg. IHWP OUT data taking.
