    Shift Summary, Feb 10, 08:00 - 16:00
    ________________________________

    08:00 - 10:15 Beam Down, PSS problems, Hall in Restricted access
    10:15 - 10:45 Adjusting good beam conditions, made harp scans, SPOT
    10:45 Started Run #2054, Kin #35 (cont.)
    ROC14 not responding. Reset BPM/Raster VME (ROC) Reset
    Maybe a junk run
    11:00 Troubleshooting ROC14, called Bob Michaels.
    Run #2055 Junk
    11:06 Run #2056 0.5M, Good Run
    11:36 MCC trying to work on higher currents, checking BCM trips
    Move to 12C target
    Made a harp scan without raster, see Halog, Dx= 82 um, Dy = 86 um
    Run #2057 Junk Run
    12:06 Run #2058 12C pointing Run
    12:10 Moving to Kin #36, p_e = 1530 MeV, Theta_e = 29.58 deg
    Cross Calibration Run
    12:40 Run #2059 1.0M , good -- Cross Calibration Run
    12:55 Moving to Kin#36, p_h = 978.7 MeV, Theta_H = 50.51 deg
    MCC troubleshooting BCM trips - will come back later with plans
    Hadron arm momentum change is taking longer than planned.
    14:00 Run #2060, 200k, good -- 12C(e,e'p) and Pointing run - No Raster
    14:15 Run #2061, 140k, good -- 4cm Dummy target - No Raster
    14:20 Run #2062, 270k, good -- 15cm Dummy target - No Raster
    14:40 Run #2063, 130k, good -- 10cm Dummy target - No Raster
    Moving to 3He, Target Controls GUI frozen. M. Kuss Troubleshooting
    14:55 MCC down with FSD trip
    15:15 Beam Back, Target Controls Back
    Start with 5uA cw.
    Do harp scans (#423) and SPOT, Run (#2064), Both show Dx = ~4.2 mm
    15:28 Run #2065, 1.1M, -- 3He(e,e'p), Kin#36, pressure=115 psi
    Trigger was not changed: Set for 1170-1700 MeV (from previous runs)
    Looks OK in analysis
    15:45 Run #2066, Junk, CODA problems
    Run #2067, Junk -- Figured trigger not set properly
    Hadron arm Trigger set for 875 - 1170 MeV
    15:50 Run #2068, 1M, good -- 3He(e,e'p), Kin#36, pressure=115 psi
    Nilanga's Analysis shows that we have ~ 62.5 K with cuts
    16:05 We are going to discuss chaning the pressure to 160 psi
