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 electronics 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
