    Swing shift summary:
    --------------------

    16:30 Still adjusting HV on Bigbite

    16:32 - 16:38 : run 1537 - 100k - ps3=500, ps6=300
    16:40 - 16:44 : run 1538 - 100k - ps3=500, ps6=100
    16:58 - 17:42 : run 1539 - 1M

    17:45 Turned BB magnet off to illuminate bottom half

    17:52 - 18:07 : run 1540 - 202k

    18:07 Turned BB magnet on to 250A (half way)

    18:10 - 18:37 : run 1541 - 568k

    18:37 Turned BB magnet to 550 A (to see top bars)

    18:40 - 19:07 : run 1542 - 716k
    19:08 - 19:43 : run 1543 - 1M

    19:44 Turned BB down to 0 to check HV on lower bars (check the new values)

    19:48 - 19:59 : run 1544 - 122k

    20:00-20:50 : Upgrade DAQ for buffered capability (Steve) . Meanwhile we are satisfied with the HV adjusting

    21:00 : Put sieve slit in for Left arm

    21:04 - 21:18 : run 1553 - ps3=5, rate is 300 Hz on LH2-4cm - 200k
    21:21 - 21:39 : run 1554 - ps6=167, rate is 300 Hz on LH2 - 200k

    21:40 Move to slanted 12C target

    21:53 - 22:17 : run 1555 - ps3=1, rate is 150 Hz on 12C - 200k
    22:19 - 22:34 : run 1556 - ps6=300, rate is ~300 Hz on 12C - 200k

    22:20 Request controlled access to check on hanging cables and low angle pin before l-HRS motion.

    23:10 Back to beam permit. The pin was moved from 15 to 14 degrees.
    23:18 Moved the sieve slit out to open collimator

    Start momentum scan, with A1 kin for 12C. open coll. Will take T3=300Hz and T6=50Hz. Adjust prescale accordingly at every target/kinematics change.

    23:27 - 23:29 : run 1557 - short run, bad prescales
    23:31 - 23:52 : run 1558 - 250k - ps3=30, ps6=1800

    Kin A1* - p=1.1259 MeV/c , L=18.5 deg
    Target:12C
    23:42 - 00:07 : run 1559 - 250k - ps3=25, ps6=2000
