Meeting time and location

  • 9:30 am EST (JLab time) remote only
  • Zoom meeting ID: 161 050 9142 Passcode: 004965

Agenda

  • Preparation for mass production of FCAL2 modules -- Sasha
    • DSG has preshaped about 300 ESR foils. Started wrapping crystals with the ESR and Tedlar (first 10 modules wrapped)
    • Loan agreement with the GWU was submitted for signatures. Two fixtures for silicon cookies were ordered. Olga is planning to come to Jlab on March 21
    • Chris continues brazing brass strap assemblies
    • Bobby has started working on honing soft iron PMT housing (quite a few mu-metal cylinders don't fit into PMT housings)
    • Igal is cutting Tedlar, Kapton, and ESR foils
  • Module fabrication -- Sasha

Minutes

Attendees: Sasha,Susan,Zisis,Phil,Arshak,Igal,Bill,Jon,Olga,Azizah,Jane

  • Preparation for module fabrication and fabrication itself continues
    • Received support from 2 members of detector support group: ESR shaping and module wrapping
    • Grand total as of meeting was 144 fabricated modules
    • Will soon need to move crystals and fabrication area to a different building
    • Some discussion of testing the modules, including using beam in upcoming CPP/PrimEx runs
      • Build 5x5 stack?
  • Arshak working on LMS
    • Contacted Carl Zorn regarding using his setup for checking transmission of light through plexiglas sheet -- equipment not working yet
  • Igal described student project 5 for dark matter searches
  • Azizah showed photon gun reconstruction efficiency as a function of φ
    • Holes at 0, 180 degrees probably due to gap between crystals
