Minutes
Attendees: Igal, Jane, Varun, Sasha, Jared, Phil, LIping, Tim W., Tim B., Susan, Jon, S.T.
- Visual inspection of 2nd batch of SICCAS crystals is almost complete (160 out 172)
- Generally better quality than first batch, but still have several discolored crystals
- Plan to measure transmittance of ~20 crystals, compare with SICCAS/Jane's measurements
- Crystals tend to be fatter in the middle compared to the ends by about 30 microns
- Plan is to clear invoice week of 11/23
- Crystal production (3rd batch) continuing
- Generally better quality than first batch, but still have several discolored crystals
- PMT divider developments: 2 bad dividers traced to sockets
- Plan is to meet with Fernando -- proceed with procurement of 150 for COMCAL upgrade?
- COMCAL -- working of improving LMS system to increase light yield
- Start construction of ~10-20 modules soon
- 60 Light guides ready to go, quality improved
- Enough anneal steel shields, brass pieces, and mu-metal shields are available
- Zisis was able to contact Eugene about a loan agreement for U. Regina
- Igal is looked at impact of applying π0 mass constraint compared to not using that constraint for analyzing π0γγ events
- Jared's work on signal PDFs for dark scalar search almost complete
- S.T. is working on simulating π0π0 background
