Meeting time and location:

Agenda

  • Preparation of parts for ECAL -- Sasha
    • - signal cables: all cables are ready. Received all needed long cables. Need to test redo 4 bundles (48 cables have been tested)
    • - signal patch panels are ready [1]
    • - HV cables: have received 50 short cables, have been testes and labeled. 440 cables are ready for installation. 36 long cables are in production
    • - HV distribution boards: Chris is finalizing design of the distribution board, should order 4 boards soon.
    • - LV cables: ordered, lead time unclear
    • - LV distribution boards. The design of the LV distribution board has been finalized (discussion with Fernando, the power regulators will not be added to the design)
    • - Optical fibers: received all
  • Ongoing projects -- Sasha, all
    • - Testing and labeling cables (Recently labeled cables in boxes)[2]
    • - Prepare modules for the TAC and prototypes (using crystals with some imperfections) [3]
    • - All optical fibers are ready for installation. 3-D printed a mounting plate to couple fibers with the integrating sphere [5] (Boby); the plate was also machined; 3-D printing a fiber tray (will be attached to the plate)
    • - Installation of the trigger and readout electronics
      • - 7 VXS crate, 3 HV crates, and 1 LV (Wiener) crate have been installed. Power lines will be installed in a week.
      • - Installed flash ADC, SDs, TIs. Uploaded new firmware [6]
      • - All readout controllers have been installed [7]
      • - Irradiation tests of the PMT active base
    • - Summer Students (2023)
  • Testing of PMT dividers -- Sasha / Vlad / Aoran / Boaxin
    • - Testing procedure [8]
    • - Tested 314 dividers [9] (59 last week)
  • Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob
  • Light monitoring system
    • All optical fibers are ready for installation, the mounting plate to the integrating sphere is under production, will be ready soon.
  • Analysis/Simulation
