    keyword=Dummy target run

    
     - moved to Dummy target
    
     - Ryan starts stepping closed the JT valve on the He target
        to park the target
     
    - 19:00 start Run 2367 - Asymmetry on dummy Al target; 
       only 31 µA possible from source. 
       
      Detector widths:   Right arm:  6583 ppm
                         Left arm:   7144 ppm
    
      detectors at only about 2000 counts above pedestal, Bryan
      raises detector voltages during this run. After adjusting
      we start a new run (Run 2368).
         new widths   Right arm: 6000 ppm  
                      Left arm: 7300 ppm
    
      so, this run will give us (if we get an hour of beam) about a 
    30 ppm error bar (per detector) or 21 ppm total error on the 
    asymmetry from our Al background - i.e. would let
    us rule out "wacky" large asymmetries from quasielastic tail
    from Al. 
    
      He target is "parked" with CHL flow at 7 g/s, 35 W on the 
    heater.
