General EEEMCal Meeting Summary 7/12/21
PARTICIPANTS: Bruno Jorion, Carlos, Irina, Miroslav, Nathaly, Pete, Renee, Crytur-CZ, Douglas, Hamlet, Hrachya, Julien Bettane, Rosi, Vardan, Vladimir, Tanja, Joerg, Lei, Sasha
EEEMCAL IN DETECTOR PROPOSALS
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
Attach to universal frame, thickness of frame - more sensitive to dead material
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 - both are implemented in
- 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
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
