    Swing Shift Summary
    -----------------------
    SL: Lisa Kaufman
    TO: Vince Sulkosky
    3rd: Daniela Rohe
    
    ----------------------
    During the shift, we took various runs on all types of targets at 1 and 5 uA.  
    We were in controlled access at the end of the shift in order to fix target 
    stuff, drift chambers, and various other things.
    ----------------------
    
    Began shift in Controlled access to fix problem with Hydrogen line (Todd 
    Averett and Ed Folts working on the problem).
    
    16:50 Everyone is out of hall.  Ready for beam again.  See halog #164234.
    
    16:52 Called for 1 uA of rastered beam - Hydrogen reference cell in beamline.
    
    17:04 Beam back.
    
    17:10 DAQ isn't working correctly.  Decide to move to no target and let Compton 
    folks do their work - still taking beam.
    
    17:17 Drift chambers turned off in preparation for higher current in the hall.
    
    17:22 10 uA in the hall for Compton.
    
    18:16 Compton studies done.
    
    18:20 Asked for no beam to move target to Hydrogen reference cell.
    
    18:26 Beam at 5 uA with H reference cell in.  Raster on.  Started taking a run.
    
    18:35 Turned front drift chambers HV on.
    
    18:37 Ran Parity DAQ to confirm that it was receiving helicity signal.  It is 
    in fact getting helicity because it measures a non-zero charge asymmetry.
    
    19:01 Changed to 1 uA running on H reference cell.
    
    19:19 Moved to C optics target.
    
    19:25 1 uA of beam on Carbon.
    
    19:30 5 uA of beam on Carbon.
    
    19:36 Moved to no target.
    
    19:41 1 uA on no target.
    
    19:46 5 uA on no target.
    
    19:55 Moved to evacuated reference cell
    
    19:56 5 uA on evacuated reference cell
    
    20:17 1 uA on evacuated reference cell
    
    20:30 Called for no beam - going to Controlled Access.
          Turned off BigBite for access.
          Taking pedestal runs during access.
    
    Shift ended in Controlled Access.
