    Kin 01
    Left: 2.216 GeV/c 21.436°
    Right: 0.989 HeV/c 54.100°

    08:07-08:33 1720 40 microamps Pb 0.04574 C. Q1 tripped.

    08:29 Q1 left tripped
    08:49 with Mark Stevens' help traced problem to the left Q1 ioc
    (hareboot7 iocha48 AND iocha48m) Ramping back up.
    09:00 Beam off for Hall C studies
    09:51 Beam is back

    09:51-10:00 1721 10 microamps Pb 0.005855 C.
    10:00-10:11 1722 20 microamps Pb 0.008497 C.
    10:11-10:37 1723 40 microamps Pb 0.0553 C.

    seeing some small evidence that we're hitting the target frame
    halog 196571. Slightly reduce the vertical (y) raster before the next

    run. (MCC y 8.0 -> 7.3)

    10:38-11:01 1724 40 microamps Pb 0.05536 C.
    10:39-11:40 1725 40 microamps Pb 0.05486 C.
    11:40-12:03 1726 40 microamps Pb 0.05544 C.
    12:03-12:26 1727 40 microamps Pb 0.05 C. (end of run missing?)

    12:27 changing to kin02 (Right arm at 59.83°)

    12:32-12:37 1728 Pb various currents and angles 0.00758 C.

    Kin02
    12:38-12:53 1729 Pb 0.006683 C.

    12:52 put in Carbon target and asked for a harp scan
    13:05 Harp scan is too large in y (0.237) e-log 1364982

    At this point I notice that the halog is having some problems
    with time keeping. Starting around 13:00 entries are appearing
    as if I made them an hour earlier (e.g. 196597, 196596, 196595)
    14:10 MCC continuing to work on vertical beam size
    14:44 elog 1364994 shows sigma_y = 0.1367
    14:50 Arun decides he wants sigma_y < 0.11
    15:07 elog 1364999 shows sigma_y = 0.0598 I think everybody is happy.

    15:12-15:14 1730 Carbon 40 microamps checking prescales 0.003191 C.
    15:15-15:53 1731 Carbon 40 microamps 0.07639 C.
    15:54------ 1732 Carbon 40 microamps
