Agenda
- SICCAS crystals
- Module fabrication
- COMCAL tests, TAC running, etc.
- Data analysis
- Simulations
- FCAL shower split-off update- Azizah
Minutes
Attendees: Bill, Jon, Phil, Zisis, Jane, Azizah, Liping, Sasha, Olga, S.T.
- Situation with SICCAS has not changed -- plan to have follow-up meeting with SICCAS contact, then discuss options with Eugene/JLab management
- In the meantime, other components for module construction continue to come to the lab:
- Received 150 PMTs: Olga checked diameters, some outliers will be traded with NPS
- Received more flanges
- Looking for vendor for 50 micron thick straps
- COMCAL has been performing well in the hall (currently being used for the PrimEx-eta experiment)
- No bad channels, new elecronics working well w/ stable gain and better linearity than before
- PMT divider redesign: Fernando developed version for NPS but is not happy with performance, not ready to go yet...
- Azizah presented her work using simulated ω→π+π-π0 events to try to separate hadronic split-offs from true photons in the FCAL
- Compared her results with those generated by Rebecca B. (IU)
- Sees some differences in distributions
- Eventually use to train machine learning algorithm (using TMVA)
- Also gave update on Varun's work using simulations of η→3&pi0; and η→2π0γ
- Compared her results with those generated by Rebecca B. (IU)
