Minutes
Attendees: Arshak,Zisis,Jane,Sasha,Phil,Tim B.,Jon,Jared,Varun,Liping,Susan,Bill B.,Olga,S.T.
- Sasha/Jane/Liping had phone meeting with SICCAS contact last Sunday
- Contact reported progress regarding lead oxide powder: SICCAS expect to receive new powder mid-July
- SICCAS will then grow some test samples (~2 week scale) to verify quality
- SICCAS also worked on reusing ingots to grow new crystals
- 3 furnaces: production rate 90/month
- Plan to add 4th furnace
- New batch by September/October?
- Contact reported progress regarding lead oxide powder: SICCAS expect to receive new powder mid-July
- Still substantial schedule risk for procuring all needed crystals by 2023
- Discussed purchasing Crytur crystals as a backup plan
- Possibly get SICCAS crystals from Hall-C (NPS plans to use Crytur crystals)
- COMCAL refurbishment continues
- All bundles for LMS are ready
- Sasha checked light transmission using black box setup, found good uniformity
- All dividers checked, bottom row reinstalled
- Reapplied optical grease for 33 modules
- Found one broken brass strap, probably weakened due to corrosion arising from flux that was not fully cleaned off
- All bundles for LMS are ready
- FCAL-2 module construction to resume in July with UNCW student help
- Maybe use FCAL-2 modules in COMCAL for PrimEx run in 2022
- Plan to submit proposal to next year's PAC to ask for more time for JEF program
- Need to redo simulations with smaller insert size
