DISCUSSION ITEMS

  • Updates on simulation, models, design
  • TCS Updates
  • Hall D plans for 2021
  • Other


PARTICIPANTS: Arshak, Bogdan, Donal, Hamlet, Tanja, Vardan, Rolf, Marie, Josh,


DISCUSSION ABOUT LOCATION OF CPS

  • Based on Hall C decision downstream


POWER DEPOSITION (Bogdan)

  • Investigating temperature-stress and ways to reduce warping
  • Gain factor of ten with Wire cut - with EDM - standard technique also for collimators
  • Still factor 6 too high, but there are other techniques one can use to distribute heat and reduce stress
  • Extend surface area to distribute heat
  • Separate top (cold) - bottom (hot)


TCS UPDATES (Vardan)

  • Clustering reduces background
  • Increasing energy threshold reduces rate to level ~100kHz
  • Actions/Questions:
  • can one select events of certain energy from cluster?
  • Are the background rates reached now sufficiently low
  • How low can one dial the time window? - currently use 50ns, fADC has 4ns resolution --> can one go to 10ns?
