General EEEMCal Meeting Summary 6/7/21

PARTICIPANTS: Bruno Jorion, Carlos, Crytur CZ, Crytur USA, Douglas, Hamlet, Irina, Lei, Nathaly, Petr, Renee, Richard, Rosi, Vladimir, Gabriel, Miroslav, Pete, Sasha

EEEMCAL IN DETECTOR PROPOSALS

ATHENA

• Discussion about reuse of materials
• Implementation in simulation DD4HEP

• Action: Check with Dmitry what is implemented and plans for hybrid, overall dimensions

• Action: in two weeks need information on EEEMCal number blocks, cost, etc. - effectively an overview of EEEMCal

• Weekly meetings: Mondays 7pm ET

CORE

• Action: check in on EEEMCAL needs

ECCE

• IJCLab working on implementation in simulation

• Geometry done - flexible radius
• Implemented algorithms for energy resolution
• Studies of pion rejection

• Full simulations will include full event simulation

• Discussion of ECCE new configuration of DIRC/EEEMCal
• Actions:

• What is the eta coverage with the new DIRC/EEEMCal configuration?
• What is the change in rates?
• Send EEEMCal cost estimate to Carlos

• Weekly meetings: Tuesdays 8am ET

SIMULATIONS:

• EEEMCAL (Carlos): see point above

• Barrel EMCAL (Nathaly)

• Working on algorithms and analysis (energy resolution, optimization of length and width of blocks

• Pion rejection (Renee)

• Summer student starting today - setting up simulation

CRYTUR PWO+SIPM DETECTOR (Bruno, Olivier, Irina)

• Studies suggest that Hamamatsu S14160-3015PS SiPMs seem a good compromise - cost same, performance similar, and lead time is less than S14160-3010

• Action: post spreadsheet for checking numbers

• Envision 16 SiPM per crystal

• All components available commercially - boards design by Crytur

• SPI Supply +-5V per crystal

• SPI ADC supply voltage 50V/crystal tower --> action: check regulations at JLab for max voltage

NEXT MEETING: MONDAY 21 JUNE AT 8:30AM ET
