    Day Shift for Saturday February 10th, 2007

       Leader:   Bryan Moffit

       Target:   Brandon Craver

       Beam Energy      = 0.362 GeV

    Summary

    Pretty smooth data taking.

    Significant Events

    • 08:00 Began shift in the middle of current scan on B4C.
    • 08:43 Moved to Li target. Asked for 1µA with 1.5x1.5 raster (MCC 6x3).
    • 09:05 Asked for 3x3 raster (MCC: 14x4).
    • 09:55 Begin raster scan on Li.
    • 10:45 End raster scan... begin moving Left Spectrometer for next kinematic.
    • 10:55 Spectrometer done moving. Start next kinematic
    • 11:37 Move to tantalum target
    • 11:55 Noticed a bump in tantalum dp. Paged brad. Suggested smaller raster for tantalum.
    • 12:15 Decreased raster size to 1.5x1.5, increased the current to 10µA and increase the prescales by x2.
    • 12:40 Moved to carbon target.
    • 12:45 Increased raster size to 3x3.
    • 13:33 Move to B4C Target.
    • 14:11 Begin moving Left Spectrometer for next kinematic
    • 14:24 Spectrometer done moving. Moved to tantalum.
