    keyword=8/9/03 day run summary

    8AM Smoothly running Kin 8.10 angle 0, beam hwp in 10 microamp
    8:47 change to beam hwp out (Kin 8.10 continuing)
    8:52 tgt position drifts. Beam off to move tgt so MCC can fix.
    9:20 MCC still trying to get tgt position right
    9:35 position OK check spot size with raster on.
    9:40 spot OK move 3He tgt back in.
    9:50 Beam back start run 2335/3335 at 10 micro
    10:50 Finish Beam HWP out measurements for tgt angle 0
    11:00 Tgt NMR polarization measurement : 36.06%
    11:05 Rotating holding field
    Hall C bleed-through measurement 1.48% (of our beam)
    (Last measure of Hall C polar was -50+/- 5%)
    11:20 Beam back and tgt unmasked-- Start Run 3338 (Tgt angle 270,
    beam hwp out)
    12:10 Put Beam hwp back in
    13:07 Kin 8.10 completed
    (Last two runs both stopped prematurely when beam position shift of .5-1mm noted. MCC doesn't understand these shifts with fast feedback on.)
    Holding field angle changed to 0
    Tgt changed to single C foil
    13:45 Magnet now set, just as MCC finishes machine diagnostic
    Start C single foil run--first part of Kin 8.11
    Beam hwp IN
    14:22 Finish setting septum (with C foil).
    Putting in empty reference cell. Raster on.
    Will do checks on position.
    14:40 MCC says sudden shifts in beam position are caused by stopping and starting Hall C beam. Correlation not explained.
    15:06 Back to standard position of reference cell. Fill with N2.
    (Lowering position of reference cell by 3mm did not change
    count rate significantly.)
    15:54 Start 3He production--run 3351, beam HWP IN, 0deg
