ePIC BIC: EOSB & SiPM's

Friday 15 Mar 2024, 09:00 → 10:30 US/Eastern

• Topics:

• Objective: Review design concepts and freeze interface specifications

• Zoom link: https://argonne.zoomgov.com/j/1614084427?pwd=NVZpZmhzeFpHOXNidlhNZ2tyVHJLQT09

 

Homework: 

• Dimensions

  • Optical cookie dimensions (1.8mm, GlueX/ECAL)? - Maria followed up with Zisis.

  • SiPM sizes (1.3 cm x 1.3 cm) - Maria followed up with Zisis.

  • Define tolerance around SiPMS and light guides (“reserved space”) (AstroPix card) -> Maria Followed up with Sylvester

  • Design goal and maximum requirement on the space for AstroPix boards -> Maria followed up with Sylvester. 

• Heat

  • heat consumption SiPM + peripherals

    • Follow-up with Norbert? (Maria) -> done, 2.5 W

  • Does power regulator etc get “hot”? -> WE DO NOT HAVE ANSWER TO IT

  • Add scale factor for Module PCB -> Module PCB generates some heat (< 20% more heat than AstroPix)

  • Need safety factor for all calculations (extra 20%, or 50% when we’re really uncertain)

  • Follow-up with Zisis on temperature stability -> Maria Followed up with Zisis

  • Need a sanity check on the cooling (follow-up with Dan?)
