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
- Link to beam tests: https://wiki.jlab.org/cuawiki/index.php/EEEMCal_Beam_Tests
- 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
