Minutes
Attendees: Igal,Jane,Zisis,Sasha,Jared,Jon,Arshak,Bill B.,Phil,Liping,Olga,Susan,Igor,S.T.
- No update on SICCAS crystals, will give a week time for response, then Sasha will email to set up follow-up meeting
- Still expecting ~700 crystals, delivery deadline for 2nd batch has passed
- Sasha met with Crytur representative, gave overview of FCAL-II project
- Crytur confirmed can provide crystals -- it seems that they have orders from other groups but they are not fully loaded
- Order (soon?) as schedule mitigation strategy? (Caveat: the Crytur crystals are more expensive...)
- PMT dividers sent to U. Regina, need to set up similar arrangement with GW
- Plan to send layout of existing divider to Zisis
- Idea is to check linearity and pulse shape
- Fernando has made some progress on divider redesign
- Sasha has constructed 2 more crystal modules, putting together construction procedure
- Igal gave update on dark scalar search effort
- Estimated sensitivity for S→2γ using backgrounds from SM η decays and 2π0
- Estimated upper limit for coupling constant g_u~7x10^-5 for 5x10^7 η events
- Can also look at S→e+e-
