General EEEMCal Meeting Summary 6/10/22

PARTICIPANTS: Carlos, Hamlet, Joerg, Renee, Richard, Taya, Vardan, Vladimir, Tanja, Sasha, Rosi, Crytur-USA

SIMULATION ACTIVITIES

• Simulation tasks related to electron endcap and barrel EMCals

• Team: AANL, FIU, IJC-Orsay, ... others interested

• U. Kentucky is interested as well

• Performance studies: resolutions, etc.

• Framework is same as usual, but need to implement the latest geometries and materials, etc.

• Discussion about which Geant4 to use (DD4HEP vs. Fun4All)

• There are several arguments for starting with Fun4All
• There are several near term items like study materials effect - largely independent of framework
• both endcap and barrel are already implemented in this framework
• in longer term a single framework is desired, but it may be neither of the present two

• Action items:

• post simulation list
• send any comments/questions for the barrel EMCal list that was circulated by the Detector-1 Calo group to Carlos or any of the other Calo Conveners

PROTOTYPE BEAM TESTS

• Completed DESY prototype tests

• good performance crystals
• SciGlass data collected - signals detected from all blocks, analysis required before one can detail performance

• JLab test preparations

• SiPMs on site and preparing matrices, boards, etc.
• beam spot identified
• chiller purchased

• Beam tests expected for September/October 2022 timeframe

• SciGlass
• Crystals/glass with SiPM matrix readout, different pixel pitch

• Crytur prototype

• components optimized for reducing heat generation
• started cosmic tests today

MEETING WITH EIC PM ABOUT POSSIBLE FUNDING

• Sent email to EIC PM - waiting for response

• Action item:

• follow up with EIC PM as needed to schedule a meeting
• gather information about international participation in NSF grants

DISCUSSIONS EIC PM EM CALORIMETERS

• Discussion about moving PWO from long lead items list

• Crytur estimate is 60-70 crystals/month
• this would mean that first orders can go into procurement in 2025

• Important to consider: Crytur has no orders beyond December 2022 - to not shut down

• a few months in 2023 at 20 crystals/month would help

• Action item: Sasha will further disuss this with EIC PM

NEXT MEETING: FRIDAY 1 JULY AT 8:00AM ET
