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 40 crystals from CRYTUR [1]. Remaining 55 crystals will be sent to us during this and next month.
      Wrapped crystals: 15
      Available for wrapping: 10 SICCAS + 25 CRYTUR = 35
    • George (DSG group) finished with preshaping.
    • More than 400 long signal cables received, can start checking, bundling, labeling (receive labeling machine in a couple of weeks)
    • Procurement parts for the LMS
      Ordered 16,400 ft of optical fibers delivered to the lab. 7,600 will be delivered in September.
      Expect to receive fiber donats in a couple of weeks (will start working on the LMS)
  • 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 'crunch' 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]
