Agenda

Minutes

Tao - SLAC analysis update, quantifying differences between QDC and GEM multiplicities, and GEM pedestal studies (ask Cameron for SLAC test beam user account on ELOG):

  • Verified that all data is complete in QDC and GEM (no missed events in one or the other)
  • Cross checked Decoder with event counter
    • Two data words encoding event number added to decoder to double check event counts
      • QDC index starts at 0, GEM MPD index starts at 1, so we expect an offset by one in these event counters
  • Trying to find another way to cross check the analysis steps
  • GEM multiplicities appear to be systematically ~15% lower than QDC multiplicities
