    Owl Shift Summary

    Michael Roedelbronn (3)

    Kinematics 5G Calorimeter 34 deg, 9.5 m HRSL 24.62 deg, 3.772 GeV/c
    5G(b) OPTICS Target 25 uA, Raster OFF
    00.41 2123 5G(b) production BPMB adjusted -2.049 +1.444

    5G(c) LH2 NO radiator 25uA Raster ON
    01.21 2124 5G(c) test run determine prescale values and calorimeter pedestal widths
    01.27 2125 5G(c) production....pedestals OK, prescales set

    5G(c*) LH2 NO radiator 5uA, Veto HV ON...VV12 ~ 1.5MHz
    01.45 2126 5G(c*) low current production
    02.16 2127 5G(c*) continue
    02.23 2128 5G(c*) continue, change Prescale 1 value

    Return to 5G(c) 25uA, accumulate another 20 min approx to improve statistics
    Veto HV OFF
    02.35 2129 5G(c) continue

    5G(d) RCS Magnet 600 A. Continue 25 uA
    02.57 2130 5G(d) production, prescale as 5G(c)

    5G(d*) HRSL 25.83 deg, p=3.494 GeV/c, Cal 34 deg, 9.5m, LH2 NO radiator,
    RCS Magnet 600A
    04.09 2131 5G(d*) test at 25 uA.....could go higher
    04.31 2132 5G(d*) up to 35 uA check prescale factors...OK, calo pedestals OK
    05.26 2133 5G(d*) probably JUNK....TS1 crashed shortly after start
    05.33 2134 5G(d*) production

    5G(e) LH2 + Radiator Target
    06.29 2135 5G(e) test at 35 uA....calorimeter pedestals too high
    06.38 2136 5G(e) reduce to 30 uA, retune prescale factors
    06.45 2137 5G(e) continue
    06.54 2138 5G(e) calorimeter pedestals high @ 30uA, data does not look good
    06.59 2139 5G(e) reduce to 20 uA, retune prescale factors
    07.16 2140 5G(e) continue, calorimeter in better shape
    07.35 2141 5G(e) JUNK ROC14 crashed after a few events
    in coincidence lost beam due to magnet problem
    07.51 2142 5G(e) restart production
