    keyword=difficult to achieve beam launch angle

    
    Attempting to deliver high current beam into Hall A.  Empty Target for recovery 
    from Hall B setup.
    
    
    06:30 - Setup for Hall B complete.  Ready for CW into Hall A.  
             Took 5 uA for raster check.
    
    06:45 - raster looks fine. Requested beam positions at BPMA_X =1.6, BPMB_X = 
    -1.4   Ops found this difficult to get to, and had to start at upstream 
    correctors.  Significant deflection necessary at 1C20.
    
    07:10 - Positions good at target BPMs, but ep Ion Chambers reading 160 Hz at 1 
    uA, and trip at 6 uA.  Ops will continue to refine the beam optics to try to 
    get these positions on target without excessive rate on ep ion chambers.
