    keyword=PMT configuration

    The PMT configuration for the hydrogen run is the following:

    ################
    ## Right Arm: ##
    ################

    Horizontal segment (high momentum): PMT Joe, base #4, filter 1/5 in front
    the PMT window

    Vertical segment (low momentum): PMT Averell, base #2, filter 1/2 in front
    the PMT window

    ###############
    ## Left Arm: ##
    ###############

    Horizontal segment (high momentum): PMT Jaqk, base #3, filter 1/5 in front
    the PMT window

    Vertical segment (low momentum): PMT William, base #1, filter 1/2 in front
    the PMT window


    To avoid non-linearity effects, PMT high voltage should be 1250 V or higher for production runs.
    Maximum voltage for counting runs is 2100-2200 V.
