    We looked at the effect of increasing beam current on the position and the width of the pedestals for the veto detectors. Thbe runs used were as follows:
    1570- no beam
    1571- 1uA, 15cm LH2 w/rad
    1572- 5uA, " "
    1573-10uA, " "

    We plotted the pedestals for 4 detectors, 2 from the central part of each veto plane: VH32 and 33, VV22 and 23. As expected, the effect was more pronounced closer to the target. Below are pictured the pedestal region of the ADC for vertical detector #23.
