General EEEMCal Meeting Summary 7/26/21

PARTICIPANTS: Carlos, Cristiano, Crytur, Douglas, Hamlet, Hrachya, Lei, Miroslav, Renee, Richard, Vladimir, Tanja, Rosi,

EEEMCAL IN THE DETECTOR PROPOSALS

ATHENA

• August 1st planned for first simulation campaign

• Opportunity for people to validate calorimeter performance in ATHENA framework

ECCE

• AI supported optimization - in process of getting started

• First simulation campaign included PWO - initial validation completed

SIMULATION UPDATE (Kheagan, Renee)

• Electron ID and Background studies

• e/pi separation
• pair symmetric background

• Started with EEEMCal response in ECCE - next could be ATHENA and CORE

• e/pi very challenging in barrel with current configuration

• Action:

• extract resolution for calorimeter and tracking and compare to Yellow Report to see if fulfill requirements

EEEMCAL DESIGN

• Attachment concept developed - now studying in detail

• Cooling combined: EEEMCal frame and from back

• need also maintain temperature

• Actions:

• check on allowable load
• Crytur prototype: check dissipation of heat from electronics
• INFN prototype: check impact on resolutoin of locating electronics at 15m away

• Impact of aging on heat output - estimation of additional heat output from sphenix?

SIPM+PWO DETECTOR

• Design ongoing

• Aim for including variety of features that will provide information for large detector, e.g., trying to monitor and/or regulate gain/bias and monitor temperature of each channel

BEAM TESTS

• JLAB: prototypes ready, two test beam periods (September ~6-27, November 15-end of run in December)

• DESY: preparations ongoing, prototype expected to be shipped in September

NEXT MEETING: MONDAY 9 AUGUST AT 8:30AM ET
