Participants: Cristiano, Sasha, Carlos, Larry, Carlos Y., Tanja, Hamlet, Julien, Renee, Hrachya, Julie, Artur, Rosi, Joerg, Olivier (Crytur-USA), Ioana, Vardan, Yeran, Dmitry


SIPM SPECS DISCUSSION (All)

  • Voltage is important if light is not mixed up well - for crystals the light is mixed well and uniform and not much sensitivity is expected
  • Variation of operating voltage of tray
  • Current design has an array of 3x3 or 4x4 SiPMs in a matrix with one output per matrix
  • May need to comment on sensitivity to gain variations between individual SiPMs - check JLab studies
  • When listing specs keep in mind the variations - tolerances
  • Efficiency cannot be changed by changing operating voltage
  • SiPM review is expected for July 2023
  • Action Item: collect all documentation on tests carried out at IJCLab-Orsay and JLab and check table entries


ENGINEERING UPDATES (Julien)

  • One of main focus areas is clearances with other infrastructure, e.g., the beam pipe and the DIRC frame - discussions are ongoing between EEEMCAL representatives (Julien, Jim, Josh) and the EIC Project technical team
  • One the integration/installation side of the EEEMCAL into the DIRC frame the rails option is being studied in details
  • assembly depends on positioning of the rails
  • Overall, need assembly space at BNL for the EEEMCAL
  • Discussion about space for cables and stress on cables in the assembly
  • general idea is to use stretchers, but more studies are planned


EEEMCAL ORGANIZATION (Tanja, Carlos)

  • Request from EPIC to provide a first draft of work packages and organizational structure
  • Discussion of two slides put together using existing material and adding in international institutions
  • Action items:
  • Update the chart directly so it looks nicer (Julie)
  • Update the numbers on page 2


ELECTRONICS READOUT (Olivier)
