Agenda
- SICCAS crystals
- Module fabrication
- COMCAL tests, TAC running, etc.
- Data analysis
- Simulations
Minutes
Attendees: Igal,Bill B.,Igor,Chase,Phil,Azizah,Jon,Zisis,Joanna,Arshak,Sasha,Varun,Olga,Jane,S.T.
- No update from SICCAS, will organize follow-up meeting in the next 2 weeks
- Crytur expressed interest in producing crystals for JEF
- Sasha continues rebuilding COMCAL (installed more PMT dividers, LMS ready to go)
- No update regarding PMT divider redesign
- Sasha starting paperwork for loan agreement with GWU
- UNCW students expected at the lab soon (next week?)
- Igal gave an update on η→π0γγ
- Looked at 1/3 of spring 2017 data set = ~10% of expected data for JEF 100 PAC days
- Compared data with MC using several different methods for analyzing data
- all masses constrained vs. π0 mass constrained vs. no mass constraints
- Chose "best" π0γγ combination based on χ^2 test
- Generated samples for TMVA analysis
- Simulated 2π0, ω→π0γ, η→3π0,... backgrounds
- Being able to test different reaction hypotheses for a given event (for example η→π+π-π0 vs. η→e+e-π0) in the works for DSelector
- Azizah gave an update on a new tool to fire 2 photons at the same time to test cluster separation
