    keyword=Shift Summary

    Shift begins with production running 4He 6% Radiator

    Left arm 2.195 GeV/c 31.982 deg
    Right arm 1.866 GeV/c 38.554 deg
    Run
    2590 in progress at shift start. Ended at 8:13 (accelerator sending tune beam)
    start/stop....run...............comments
    8:26/9:18....2591
    10 cm dummy 6% radiator
    9:29/9:30...2592..........deadtime = 0 adjusting prescales
    9:31/10:03..2593

    10 cm dummy radiator out
    10:06/10:44 ...2594

    9-foil optics target radiator out
    10:59/ 11:15.....2595

    Moved left arm to 38.54 degrees changed p0 to 1.866 GeV/c. Loaded new trigger.
    11:30 kcoda, reboot TS0 and TS1, restart CODA as directed by Bob Michaels (response to failure of datamon to work)
    11:35 low ESR pressure alarm. K McCormick consulted. Not a problem, low pressure is 15K line which we're not using. (see halog 57949)

    10 cm He with 6% radiator
    11:45/ 11:51.....2596 prescales need adjusting
    11:52/12:30......2597

    10cm He no radiator
    12:32/12:50.......2598

    Move spectrometers
    Left:
    P0=+1.642
    41.696 degrees

    Right:
    P0=-2.363 (this takes time!)
    Q2 and Q3 were cycled.
    27.572 degrees

    New Trigger loaded

    10 cm 4He target, radiator out

    13:42/14:42......2599
    14:42/15:51......2600

    10cm 4He target, 6% radiator in
    15:53/........2601 passed on to swing shift

    Good beam all day!
