    Owl Shift Summary for Feb 07, 2009

    Workers: Yoomin Oh, YaWei Zhang

    L-HRS at 45 degree, P0 = 600MeV.

    00:00 Target work
    01:10 Beam permit, starting BPM scan
    02:00 Brad found that the target ladder camera doesn't show what it
    is supposed to be show, asked for controlled access, called JP.
    03:30 JP and Yawei in the hall to fix the camera related issue.
    05:20 Beam permit
    05:40 Checked BPM--spot size is ~2mm x 2mm, by the way, spot++ does not
    work, it seems that spot++ is looking for a BB run rather than
    for a L-HRS run
    06:00 Raster size checked with reference cell(nitrogen)
    From 3x4 to 6x6 (in MCC unit), seem fine
    07:00 Started BPM calibration with single foil optics target,
    but no good beam since started.
    08:00 BPM calibration starts with BPMs at (-2,-2)
