SUMMARY NOTES

NPS LOGO


FRAME

  • On the path to going back to normal operations
  • Current estimate - shipment to JLab before Christmas


MAGNET

  • Work ongoing


CRYSTALS

  • Characterization of latest batch from Crytur ongoing today


HV DIVIDERS


MECHANICAL (Paulo)

  • Platforms etc. reqs signed off
  • Currently working on rail mounting (rails themselves are in house)


NPS CALIBRATIONS (Jacob)

  • Overview of NPS calibrations for DVCS kinematics
  • Rates favorable - at least one kinematic can be done in one day
  • Discussion about acceptance coverage - appears to be quite small
  • Next topics to be investigated: HMS magnet calibration, Simulation development


TCS PROPOSAL (Marie, Vardan)

  • Discussion of the TCS proposal slides
  • Page 4: make horizontal axes the same
  • Clear definition of geometry of hodoscope (2x2, how deep), what is the rate in one of these channels
  • Specify granularity, e.g. GEM counters
  • For calorimeter use higher than 1 MeV threshold
  • Calibration of calorimeter - can one do in situ with elastics for energy calibration and resolution? - if assume yield changes by 10% over course of experiment due to radiation damage
  • Updated proposal will be circulated for further comments


NEXT MEETING: THURSDAY 9 JULY AT 9AM (ET)
