  • Discussion about updates to table based on feedback from 6/23 meeting with EIC PM
  • Recap of updates made:
  • Added funding information
  • Added assumptions of what comes from the EIC Project
  • Added NPS project major institutions for comparison - there are 5 major institutions
  • Added two new institutions: Ohio U., ACU
  • With the two new institutions the EEEMCAL Consortium includes 12 major institutions
  • Other items to consider adding to information collection: number of channels
  • Endcap ~3200 channels
  • Barrel >=8000 channels (= assuming light guide, > assuming no light guide and back face is larger than front face of block)
  • Another example of similar systems built by universities: STAR EMCal endcap
  • roughly 5 major institutions
  • could be used as another example to illustrate
  • Action items:
  • send updated table to EIC PM
  • invite OU and ACU to future EEEMCAL meetings


  • Simulation efforts are ongoing within EEEMCAL to make case stronger for the homogeneous BarrelEMCal and to optimize together the configurations/performances of the electron endcap and the Barrel EMCal
  • Dedicated meetings focused on calorimeter simulations - next one scheduled for next week
  • Friederike Bock will join contributing Fun4All knowledge on the calorimeter simulations
  • The EEEMCAL simulation team:
  • lead: Carlos
  • presently contributing: AANL, FIU, U. Kentucky, CUA (focus on mechanical model), W&M (on AI/ML)
  • interested in joining the meetings: JMU, Sasha B.
  • Focus areas to make the Barrel EMCal case stronger
  • pion rejection power with high efficiency for electrons
  • separation power for pi0 from merged photons
  • For pion rejection power the areas of optimization - related to the tails - are:
  • material in front
  • depth of calorimeter
  • gaps between modules --> seems to be the main source of the tails in the Fun4All implementation and needs to be addressed going forward
  • Gaps between modules - sufficient to have air or would a material be needed?
  • Yes, a material should be used - carbon fiber
  • Mechanical model details - contact Josh Crafts for model files
  • currently working on developing model of light guides and PCB/readout electronics
  • Optimization studies of both endcap and Barrel EMCal (U. Kentucky)
  • general idea: follow the path of tracking and optimize endcap and barrel EMCal together
  • developed a list of parameters
  • need the simulation to run interactively - met with Joe O. and Jin H. about running Fun4All in this mode
  • tracking can run interactively and fast; calorimeters take much longer
  • Timeline of the EIC Detector-1 Calorimeter WG: decision on Barrel EMcal will only come after the July 2022 EICUGM


  • DESY: analysis ongoing of data from May 2022 run; another test beam period presently scheduled for 15 - 28 August
  • initial results from May test expected at DNP
  • possible goals of August test:
  • finer granularity horizontal scan
  • long SciGlass blocks - conflicts with the planned JLab prototype tests
  • Crytur small prototype test - would require JLab electronics, but these have been shipped back
  • JLAB: two main goals: 1) SiPM readout; 2) SciGlass long blocks
  • preparations ongoing for the SiPM readout at JLab and Crytur - focused on different approach to SiPM array and PCB electronics
  • preparations ongoing also for SciGlass - large blocks are being prepared
  • AANL: constructing a prototype with focus on the low energy region (30-70 MeV)
  • experiencing problems with Hamamatsu
  • possible avenue through EIC R&D
