    keyword=Run plan for Monday Day and Swing

    
    Status: 
    We continued to take production data overnight. This morning we took a
    Controlled Access to re-configure for elastic running at 4 pass.
    
    Plans:
    During Day/Swing shift we took (will) take elastic data with protons in
    the left HRS and electrons in the calorimeter in order to calibrate the
    calorimeter HV.
    
    We are in the process of taking data at each of the following kinematics:
    
    Elastic 3 (Ebeam = 4.454 GeV nominal):
    
    Theta_calo = 24.3 degrees, distance from target = 5.5 m
    
    a)P_HRSL = 2.254 GeV/c, Theta_HRSL=36.30 degrees
    b)P_HRSL = 2.131 GeV/c, Theta_HRSL=37.86 degrees 
    c)P_HRSL = 1.981 GeV/c, Theta_HRSL=40.00 degrees
    
    Plan:
    
    Once we are finished with one pass through each of the 3 settings above,
    we will take a couple hours to try and get good background rates in the
    Compton. This will give Carlos a chance to analyze the data above. He
    will then update the HV, and we will take another pass through the above
    settings.
