Meeting time and location:

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

Agenda

  • Preparation of parts for FCAL2 modules -- Sasha
    • Crystals:
      Received 30 crystals from CRYTUR [1]. Remaining 65 crystals will be sent to us during this and next month.
      Wrapped crystals ready for fabrication (Mindy): 26 SICCAS and 5 CRYTUR = 31
      Available for wrapping: 10 SICCAS + 28 CRYTUR = 38
    • George (DSG group) preshaped 96 ESR reflectors; finished with preshaping.
    • More than 200 long signal cables received, can start checking, bundling, labeling
    • Procurement parts for the LMS
      Ordered 16,000 + 8,000 = 24,000 ft of optical fibers. Expect that the first batch will be delivered in May.
      Ordered 18000 of polycarbonate donats. Will be available in 3 - 4 weeks.
  • Module fabrication -- Sasha
    • Fabricated modules: Total 1487
      Available for fabrication: 31
      First summer students (Madison and Madelyn) are in the Lab. They fabricated 26 modules using 'low quality' crystals for the stacking mockup and 'crash' tests. We have a total of low-quality crystals for 42 test modules.
  • Testing of PMT dividers -- Sasha / Vlad / Arshak
    • FCAL2 modules with dividers installed on the CCAL [2]
    • Met with Vlad P. on Tuesday. Fine tuned the divider circuit. Checking/tuning an amplifier; Chris S. ordered some OPS.
  • Installation of the FCAL2 detector & integration to GlueX -- Sasha / Arshak
Discussion of the FCAL2 installation procedures [4]
  • Preparation of parts for FCAL2 modules -- Sasha
  • Module fabrication -- Sasha
  • PMT divider updates
  • Light Monitoring System -- Arshak
  • Simulations/Analysis
  • GUINEAPIG Workshop?
