Agenda

Minutes

Attendees: Varun,Sasha,Igal,Jon,Zisis,Liping,Jane,Susan,Tim B.,Tim W., Phil, Josh, Bill B.,S.T.

  • No news from SICCAS -- Sasha will contact them
  • Vlad B. was given permission by physics management to go on site to work on Hall C CRYTUR crystals, maybe he can start looking at dimension checks of our crystals?
  • Josh scheduled to be allowed on campus on Monday 7/13 -- work on our crystals? OSP for clean room: additional COVID-19-related checklist
  • Reworked mu-metal shields have not shipped yet
  • New light guides not shipped yet
    • Pending arrival of these (and assuming they pass our checks), we have enough material to assemble ~10 complete modules (already have 2, look good)
  • Test setup in hall (on pair spectrometer arm) ready for beam
  • Work continues on PMT base redesign, goal to have ~2 ready for beam
  • Igal is working on η→π0γγ simulation -- not using standard DSelector for analysis due to too many combinations
    • Choose "best" combination? What to do with multiple "good" combinations?
    • FCAL shower quality cut effective for cutting hadronic spitoffs -- repeat ML training for insert?
  • Island algorithm: implemented for CCAL, S.T. will look at incorporating it for FCAL/FCAL-II
  • Liping asked for feedback on review article on "Precision tests of fundamental physics with η and η′ mesons" [1].
