    Kinematics #7, Pb target, 2.634C so far


    Run, #Ev, Q (C), total Q (C)
    1593, 0.5M, 0.028, 2.662
    16:20 reduce raster from 6.4x9.2 to 6.4x8.5 (MCC values) in order to reduce raster y size from 6.5 to 6.
    1594, 0.5M, 0.029, 2.691
    16:35 reduce raster to 6.4x8.0 (MCC values) (nb: MCC number is 7046)
    1595 - garbage, raster was changing during the run
    1596, 0.6M, 0.034, 2.725 ended run due to lost beam
    17:10 beam back at 10uA, start run 1597
    1597, 0.1M, 0.007, 2.732
    17:20 20 uA
    1598, 0.2M, 0.009, 2.741
    17:30 40 uA
    1599, 1M, 0.053, 2.794
    1600, 0.3M, 0.017, 2.811 ended when right arm IOC crashed
    18:06 rebooted IOC. Right NMR failure. Cycled NMR power three times until it came back.
    18:31 start next run
    1601, 1M, 0.054, 2.865
    1602, 0.3M, 0.017, 2.882 ended when we noticed bad magnet values written to beginning of run halog entries. Note that the gui values were updating properly and the magnet values were all correct (ie: green). The T3 rates look OK too so the data should be OK.
    Reboot the IOC and cycle power to the NMR. Wait 30 minutes for the dipole to settle back to the correct value.
    1603, 1M, 0.054, 2.936
    1604, 1M, 0.054, 2.990
    1605, 1M, 0.054, 3.044
    1606, 1M, 0.054, 3.098
    1607, 1M, 0.054, 3.152
    1608, 1M, 0.054, 3.206
    and one last run to make up for the short questionable runs
    1609, 1M, 0.054, 3.260
    end of kinematics
    Move HRS-L to 42.582 degrees for kinematics 05
    Harp scan gives sigma_y = 0.281mm Too High!
    Ask MCC to tune
    New scan has sigma_y = 0.076
    Switch to carbon target
    Start run 1610 at 23:06
    Carbon run 1610, 0.58M events, 0.115 C
