Review of minutes from the previous meeting
We looked at the minutes from August 16th. Since the last meeting, Beni has produced updated plots of efficiency versus run number with error bars.
Run Plan
Beni and Brad have been working on new code to get an estimate of good starting values of the high voltage based on the HV scan done at the beginning of the Spring 2016 run. It plots the pulse amplitudes versus end-to-end time differences. The idea is to find, for each tube, the lowest voltage that will put the pulses above discriminator threshold for a minimum ionizing hit at the far end. These results will have to be adjusted for long-term gain reduction suffered during the run. The exercise will be repeated with beam data once that is available.
