Revision as of 09:13, 28 April 2023

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:
      10 CRYTUR crystals (out of 95 [1] ) were sent to us last week
      All crystals from the CCAL prototype were removed
      26 crystals were wrapped by Mindy
      Number of available crystals: 1487 (modules) + 26 = 1513, expect to receive 95 from CRYTUR: 1513 + 95 = 1608 (12 spares)
    • George (DSG group) unwrapped CCAL modules and removed LMS caps. Preshaped 48 ESR reflectors, have to preshape 32 more.
    • More than 200 long signal cables received, can start checking, bundling, labeling
    • Procurement parts for the LMS
      Ordered 16,000 ft of optical fibers. Expect that they will be delivered in May. Adding additional 8000 ft to the PO
      Ordered 18000 of polycarbonate donats
  • Module fabrication -- Sasha
    • Fabricated modules: Total 1487
      Available for fabrication: 26
      Fabricate 36 modules using 'low quality' crystals for stacking mockup and 'crash' tests (train students on them)
  • 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 (modified some resistors). Chris S. ordered new parts
  • Installation of the FCAL2 detector & integration to GlueX -- Sasha / Arshak
Discussion of the FCAL2 installation procedures [4]
