Gains for each PMT/base combination to be used for the beamtest have been tested. Our method was to place two triggers on top of each other, and count the coincidence rate of cosmic rays as we vary the HV on the trigger we want to test. The other trigger was kept at 1700 V. Below are plots for the gain adjustments. There are 10 trigger scintillators, and 1 remote trigger.
