    keyword=scan of adc gate

    scan of adc gate. After the width of the ADC gate was changed to 100ns
    the delay of the hadron arm was varied to find the maximum in the
    adc value for the lead glass. Measured the peak position of the
    adc in two blocks. For delay three channels were used and
    each bit in the channels 8ns

    Run gate width delay adc peak block 22 adc peak block 24

    Decide that delay of 14,11,12 was best for both blocks.
