    2/13/03 day shift summary:
    Shift workers: S. Choi, J. P. Chen, N. Liyanaga

    8:00 beam half-waveplate change to be IN.
    8:05-9:00 Smooth data taking at kinematics 6.3.7. Beam half wave plate IN, target
    at 180 degree.
    9:00- 12:00 planned controll access for spectrometer survey (at 32 degrees)
    and Beam study by MCC. Also rebooted target ioc. GEn detector setup
    to get ready for the neutron test tonight.
    9:10 NMR=37.0%
    Spectrometer survey completed half hour earlier. Hall came out of controlled
    access at 11:50.
    At 13:30 beam back. Raster check and raster size study (0.5mm, 2mm and 4 mm)
    14:04 NMR=39.2%
    then continue data taking at 6.3.7.
    15:20 completed data taking at 6.3.7. Changed to 6.3.3 beam half wave plate in,
    target at 0 degree.
    15:26 data taking at 6.3.3.

    Run 1971/20971 kin 6.3.7
    1972/20972-1977/20977 rastercheck/study with BeO/12C
    1972/20972: < 2 uA, raster on, short run
    1973/20973: raster 5.7mm MCC (spot=4mm), 12 uA
    1974/20974: raster 2mm MCC, 12 uA
    1975/20975: raster 0.5mm MCC, 12 uA
    1976/20976: raster off, 5 uA,
    1977/20977: raster 3mm MCC (spot=4mm), 5 uA
    Note: with 3mm or above MCC, it was saturated.
    1978/20978 kin 6.3.7
    1979/20979 kin 6.3.3
