Agenda

• Preparation of parts for ECAL -- Sasha
  • - signal cables: all cables are ready. Received 100 long cables. They have been tested, labeled and bundled (will be used to replace FCAL cables removed from the FCAL). Need to redo 10 bundles.
  • - 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]
    • Wrapped crystals
    • Parts for TAC[4].
    • Modules for prototype (25 are ready). All parts are ready to assemble 30 CCAL-style modules.
  • - 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]
