Agenda

Minutes

Attendees: Liping,Igal,Phil,Zisis,Tim B.,Sasha,Jared,Jane,Susan,Arshak,Josh,S.T.

  • Phil's NSF grant was approved (congratulations!)
    • In discussions to join JEF
    • Has a student (Jared) interested in coming to JLab to participate for 10 weeks in the fall
  • No news on crystal production
  • New light guide samples have cloudy surfaces; sent back for vapor polishing.
    • Found another vendor
  • Samples of mu-metal cylinders have joint problems, need to be fixed.
  • PMT active base design: Sasha working with Fernando and Vlad P.
    • Fernando will purchase needed HV -- chosen version has caveat: limited to 1 mA/channel
      • Would need to modify current base design to <800 micro-Amp, which could affect linearity
    • Asked to produce dividers for use in COMCAL
      • COMCAL HV limit is 3 mA/ channel (30% more expensive than 1 mA version)
  • Josh coordinating between Tim B. and Fernando to send gaussian pulser to UNCW for PMT/base tests
  • JEF will make a ~2 page contribution to Snowmass in July
  • Simulation: there was some discussion regarding who will look at what channel
    • Susan is interested in η→π0γγ (already starting to look at GlueX data) and transition form factors
    • Jon Z. is looking at η→3π0 (background to π0γγ channel)
    • Beyond standard model studies -- Igal
    • We decided to make these kind of studies a more regular feature of the JEF meetings
  • Igal will submit an abstract for the fall DNP meeting.
