    Day Shift for Monday February 12th, 2007

       Leader:   Bryan Moffit

       Target:   Elena Khrosinkova

       Beam Energy = 0.362 GeV

    Summary

    Significant Events

    • 08:00 Began shift by moving the target to B4C.
    • 08:10 Discovered we were actually on C. Moved to B4C.
    • 08:12 Performed Alexander's requested DAQ deadtime test with trigger-4.
    • 08:20 Return to production.
    • 08:51 Starting Beam Calorimeter/BCM calibration.
    • 09:15 Starting BCM calibration/Rate study.
    • 10:34 Starting Bullseye scan. Raster turned off.
    • 11:58 Raster back on. "Pedestal" run for left arm.
    • 12:11 Back to production on B4C.
    • 12:40 Move to Li target.
    • 14:56 Start moving left spectrometer to 24°
    • 15:26 Done moving. Starting again on kinematic A.
    • 15:58 MCC informs us that beam is gone for awhile, while they make some polarization measurements.
