    Swing shift summary

    Shift workers: J. P. Chen (SL), M. Yurov (TO), C. McLean (3rd)

    16:00 restricted access for beam study

    20:00 back to controlled access.
    21:00 MCC called to say they are going to send tuning beam
    21:30 Tuning beam to Hall A
    22:00 Beam to CW. 100 nA, moved to 12C hole.
    Centered beam on the target and minimize 3rd rate/3rd arm raster
    pattern.
    (Turned on fast raster 2mmx2mm. Turned on slow raster, 1.1V (1.6 cm).
    then Turned off faster raster).
    Moved to the 12c target. Increased slow raster to 1.3 V and then to 1.5 V. Rates in 3rd arm did not change much.
    Turned on faster raster to 2mmx2mm. Rate increasted by a factor of two. Centered some more and then reduced slwo raster to 1.45V (2 cm).
    Rates looking good and raster pattern looks good. (See Pengjia's Alog for a summary.
    24:15 Completed beam position and raster size check.
    24:24 set septum and ready for optics run.
