    keyword=Calibration of Hall C IA

    Hall C IA was roughly calibrated during HAPPEx run# 2280.
    The slope is 850ppm/volt. Hall C IA set point has been changed from 5 to 7 DAC Volts to zero the bean curent asym in hall C (-1400 down to 20 ppm).
    We observe 2 side peaks 10000ppm (1%) away from the central one which could be due to history effects.
