SIPM SPECS DISCUSSION (All)
- EIC Project requests SiPM specs table for EEEMCAL: Official spreadsheet at this link
- 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
