General EEEMCal Meeting Summary 11/3/23

PARTICIPANTS: Justin, Josh, Renee, Richard, Tanja, Sasha, Rosi, Carlos, Joerg, Ioana, Crytur-USA, Douglas, Pete

MECHANICAL DESIGN

• Work ongoing

• to proceed waiting for decisions on electronics/RO and interfaces with external infrastructure (supports, other detectors, etc.)

• Prototypes for beam test campaigns

• IJCLab-Orsay 5x5 prototype with cooling
• MIT 5x5 prototype with cooling
• Crytur-USA 3x3 prototype with 15um SiPM 3x3mm3 devices (16/crystal)

• Possible beam tests - ongoing planning

• JLab Hall D is available September 2024 - May 2025
• CERN - discussions with Norbert; this would be mixed beam
• DESY

• Action items:

• request time for Hall D prototype testing
• follow up on CERN beam time
• follow up with Douglas on beam test possibilities at DESY in summer 2024

• Pion/hadron beams

• presently considering measuring hadron response with low energy proton beam
• perhaps the CERN beam can serve as pion beam test

READOUT/ELECTRONICS

• Irradiation of SiPMs

• there is a facility at UMass-Lowell that has been used for sPHENIX - a fee is required to use this facility
• tests are presently being planned through collaboration with Giessen U. at low energy hadron beam facilities

• Discussion of needed performance parameters
