    Entry number 136070

    keyword=HV Proton

    The Proton Array HV GUI has changed, and the number that is nedded to enter in the text entry box is the number in the "id" column from the table below. The Coef column shows calibration coefficent for given id.
    For neutron runs the "id=6" must be tried first. If the rates are high on first ( and last) two towers the HV can be switched to id=10.
    the id=16 has lowered gain for towers 1-4 and 17-20.
