PARTICIPANTS: Vardan, Pete, Richard, Mirek, Justin, Carlos, Casey, Dmitry, Hamlet, Douglas, Hrachya, Sasha, Michael, Tanja, Irina, Renee, Philip, Patrick Moran,


DESIGN/ENGINEERING

  • Work ongoing on prototype


READOUT/ELECTRONICS

  • Order in for SiPMs 10um, 15um, and different device sizes
  • Larry I. made drawings for 2x2 matrices based on the earlier 3x3 matrices made by Steve Titus for the prototypes at JLab
  • Irradiation preparations
  • Discussions with UC Riverside
  • Follow up with UMass/Lowell - requires investment of ~$4k for one irradiation
  • Follow up with Giessen U. - parasitic test and will be done by the group when possible
  • Test bench tests with SiPMs and/or tests with beam - need to develop a concrete plan for this including goals and how these will be achieved before Sept 2024 (TDR date)
  • Test beam availability
  • CERN: March/April
  • DESY: requires submission of a request around March for beam time in summer
  • JLAB: available anytime (parasitic with main experiment in Hall D) after Sept 2024
  • Prototypes available
  • MIT: 5x5 PWO + PMT
  • CUA/JLAB: 3x3 + PMT, 3x3 + SiPM, 5x5 + SiPM (requires modifications)
  • Crytur USA: 5x5 + SiPM
  • IJCLAB/Orsay: 5x5
  • AANL: 4x4
  • Action: Justin will call dedicated meeting on SiPM/readout electronics tests


CRYSTALS

  • Size of the crystals is essentially fixed at this time
  • Strong motivation for 20.5mm x 20.5mm since Crytur already made hundreds of crystals stockpiled (never stopped production since Sept 2023, so have order hundred of crystals now)


DISCUSSION OF TDR PLANNING FOR EEEMCAL


  • In general, EEEMCAL is in good shape.
  • energy resolution can be shown against requirement
  • plots could again start from electron purity plot, then e-p separation etc.
  • Remaining items that need to be completed before final: mainly SiPM choice and readout choice
  • For electronics/readout overall need to complete investigations of stability, linearity, and power deposition for the two approaches (discrete and ASICS).
  • Beam test goals:
  • test if ASIC gives comparable result with fADC
  • what is the minimum energy that can be detected with both sets of electronics
  • SiPM choice should be made before beam tests with only one channel. Idea is to use only one type of SiPM for the beam test. This can be done with cosmics. For SiPM need to decide between 10um and 15um - one of the differences is nonlinearity
  • List from collaboration/project - action: write a short narrative that addresses these points and store it in an accessible location
  • The lab/testbeam/prototyping needed;
  • Need to complete readout/electronics choice - some can be done with cosmics (SiPM choice) and some tests require beam. Test beam tests planned for time frames: March/April (CERN), DESY (requires submission of a request around March), JLAB (available after September 2024)
  • The further progress needed for the reconstruction software;
  • In general we welcome any quality-of-life improvements in reconstruction and analysis software. In the long run we are lacking Event Data Model (EDM) definitions to encode PID hypotheses to be delivered by calorimeter reconstruction (suggested text from Dmitry)
  • The verification of the implementation of the detector and detector response in simulation and validation using information from lab/testbeam exercises or from literature;
  • Need to complete the tests pertaining to readout/electronics
  • The studies required to demonstrate the detector performance;
  • similar to previous item
  • The required engineering design;
  • see update slides from Julien and fill in here
  • The needed resources to achieve 60% (CD-2) and 90% (CD-3) design completion;
  • The plan should include the time required to draft the text for the

pre-TDR (CD-2) and TDR (CD-3).
