Agenda

  • Cameron and Chandan : Ask Bob about problems from yesterday

Minutes

  • Morning - 9AM - Bob, Cameron, Chandan :
    • The LHRS and RHRS have all of their HAPPEX and QWeak ADCs tested
      • Issue: There appears to be a PAN issue with reading the data and messing up the signed vs unsigned integer which causes the intended centering around the mid point of the dynamic range to end up as centering about 0/max value
      • This is a software issue that can likely be easily fixed and has no effect on the raw data files
    • We didn't test HAPPEX ADCs in the counting house yet
      • Issue: The Counting House DAQ (ROC 23) doesn't allow us to change HAPPEX ADC Gains within the RampTest.crl readout list on the fly
      • This is due to some persistent problems with the counting house DAC that can be circumvented by just doing the DAC12 ramp without changing gains
      • So just assume a good gain and verify that it doesn't saturate and we are good
    • There is a standalone .crl for the injector
      • So we can just move our RampTest.crl ramping functionality into a copy of it
      • However, there is no HAPPEX Timing Board in the Injector, and so doing ramp tests is not immediately possible
      • Because other people are using the Injector DAQ we will not add a HAPTB to it right now, but it should be very simple to do
      • So then we just would need to add the HAPTB handling code from Prex_ts.crl into Injector.crl and proceed
