    keyword=Shift Summary

    Run summary of swing shift, 1/16/01

    16:00 - 17:30 Beam finally available. The trigger file, coin17, is downloaded. Beam spot position is tuned to X=2 mm and Y=0 mm. Turn off Raster. Moved in 12C target (9 foil). Start run 1380, but found left Q2 tripped. reset the magnet.

    17:30 - 19:00 Struggle with the scalers and PS factors. Turned the pulser OFF to make sure we have seen the events from carbon. Below are some good optic runs:

    Run start/stop Nevents comments
    1384 18:46/19:08 210k Good optics run
    1385 19:10/19:21 160k Good optics run

    19:35 Turned on the raster, reduce beam current to 3uA, checking the spot size.

    1386 19:33/19:43 100k spot check run
    1387 junk

    19:45 Asked for the 6% radiator, moved to 15cm D2 target, increase beam current to 30uA.

    1388 19:50/19:53 tuning the PS factors
    1389 19:56/20:09 130k production run; prescale factors 4/4000/7/7000/1
    1390 20:12/20:21 junk. Beam is off

    20:23 Turn ON the pulser

    1391 20:26/21:02 550k stopped for beam optics adjusting
    1392 21:20/22:32 1M good run

    22:35 Move out the radiator. Increase beam current to 40 uA.

    1393 22:41/23:11 333k radiator out. 15cm D2 target, prescale factors 3/2000/4/3000/1

    23:12 Move to H2 target.

    1394 23:22/23:26 7k Spot check run. Run at 5 uA.
    1395 23:30/23:32 14k Changed to 40 uA, Adjust prescale factors to 2/1000/2/2000/1
    1396 23:34/ continue to next shift
