EEEMCAL IN DETECTOR PROPOSALS

  • Detector looks similar in all three proposals
  • differences in size and number of PWO vs. Glass
  • there may be differences in attachment - ATHENA and ECCE assume mounting on universal frame; CORE has been assuming mounting to endcap HCAL frame, but recently moved away from it - CORE more sensitive to impact of non-sensitive material regions


  • ATHENA:
  • z = 195cm
  • R_in = 11 cm (eta ~ -3.5) = R_min_PWO
  • R_max_PWO = 53cm (eta ~2) = R_min_Glass
  • R_max_total = 100 cm (eta ~ 1.4) = R_max_Glass
  • Modules PWO = ~ 2200 (2 x 2 x 20 cm3)
  • Modules Glass = ~ 1400 (4 x 4 x 40 cm3)
  • Total weight: ~ 2400 kg
  • If assume all PWO for this volume: 7600 PWO modules
  • Weight ~ 7000 kg


ECCE:

  • z = 190 cm
  • R_min = 11cm (eta ~3.5) = R_min_PWO
  • R_max_PWO = 49cm (eta ~2) = R_min_Glass
  • R_max_total = 57 cm (eta ~1.9) = R_max_Glass
  • Modules PWO = 1680 (2 x 2 x 20 cm3)
  • Modules Glass = 160 (4 x 4 x 40 cm3)
  • Total weight: ~1500 kg
  • If assume all PWO for this volume: 2960 PWO modules
  • Total weight ~ 2000kg


CORE

  • z
  • R_min
  • R_max


SIMULATIONS

  • Tolerance material in front of EMCal - ongoing studies
  • e/pi studies ongoing
  • ECCE produced some simulation data samples that are used for these studies
  • implementations - completed
  • barrel SciGlass (Nathaly)
  • EEEMCAL Fun4All (Carlos)
  • EEEMCAL DD4HEP (Vladimir/Dmitry)
  • ATHENA simulation campaign planned for August
  • Will include hybrid EEEMCal
  • ECCE simulation campaign 21 June uses PWO only EEEMcal and sphenix barrel EMCal(?) - does not yet have EEEMcal hybrid or SciGlass barrel
  • hybrid EEEMCal and Sciglass barrel will be in next ECCE simulation campaign


DESIGN EEEMCAL

  • Initial design prepared
  • Cooling would be water cooling around circumference plus possible mechanical cooling from the back
  • must also take into account cabling from back
  • Beam pipe characteristics around the detector - diameter etc.
  • Main questions:
  • beam pipe
  • support limitations at universal frame
  • thickness of outer and inner radius
  • Action items:
  • prepare summary of questions
  • discussion with EIC PM


PWO+SIPM DETECTOR UPDATE

  • Found a way to include 16 SiPM per crystal
  • Discussion about services and integration for beam test
  • Action item:
  • prepare list of services needed for discussion with HallD electrical engineer


BEAM TESTS 2021

  • If planning to participate please contact:
  • For DESY tests: Douglas Hasell
  • For JLAB tests: Tanja Horn


NEXT MEETING: MONDAY 26 JULY 2021 AT 8:30AM ET
