    keyword=A1 should be OK for now

    After we changed two bases for A1, we took pedestal runs , then we adjusted HV, now, A1 should be ok. The total sum is different from between with beam and without beam. The first peak is the single photo-electron peak(without beam). The currents become reasonable for all the channels.
