    Owl Shift Summary for 2/13/2003
    R. Feuerbach
    V. Sulkosky

    Started shift at the 6.3.7 setting.

    23:53 - 0:56 Run 20962/1962/1965 with 277k/247k events, good: 4.3k/4.0k

    0:59 - 2:02 Run 20963/1963/1966 with 269k/234k events, good: 4.0k/3.6k

    2:02 Finished with 6.3.7 configuration for now, with an accumulated 23k "good" events. Performed an NMR target polarization measurement while moving the Beam half-wave plate OUT.

    Changed to 6.3.8 setting
    HWP OUT, RWP 6200, PC-pos 7.673, PC-neg 7.569

    2:09 Asked for beam back after NMR measurement. Target polarization measured to be 38.1%.

    2:10 Tried to start runs 20964/1964/1967, but the Left arm failed due to TS1 failing to report. Rebooting TS1 solved the problem. In the meantime, events from the Right HRS were collected to run 1964, with 21.6k events, good: 279.

    2:19 - 3:21 Run 20965/1965 with 265k/235k events, good: 3.9k/3.6k.

    3:23 - 4:25 Run 20966/1966 with 263k/234k events, good: 3.8k/3.5k.

    4:27 - 5:31 Run 20967/1967 with 265k/238k events, good: 3.8k/3.6k.

    5:33 - 6:32 Run 20968/1968 with 255k/224k events, good: 3.6k/3.4k.

    6:33 - 7:32 Run 20969/1969 with 226k/202k events, good: 2.9k/2.7k.

    7:32 - 8:00 Run 20970/1970 with 117k/104k events, good: 1.5k/1.4k.

    Finished 6.3.8 setting, with 38.1k "good" events

    8:00 Insertable Beam half-wave plate put IN, and Rotateable wave plate and pockel cell settings changed as noted in the halog entry.

    Starting 6.3.7 setting again

    8:01 Started run 20971/1971.
