Agenda

• Preparation of parts for ECAL modules -- Sasha
  • Crystals:

    - Prepare to send 11 crystals back to SICCAS [1].

  • Received 1100 short signal cables [2]
  • Received 140 HV cables
  • Received 24,400 ft of optical fibers.
• Module fabrication -- Sasha
  • All modules have been fabricated, checked, and inventorized (about 1610 modules in total)
• Ongoing projects -- Sasha, all
  • Visual inspections of fabricated modules [3] - done
  • All crystals moved to Hall D[4] [5][6] - done
  • Tested, labeled, and bundled all 100 (+ 2 spares) [7] signal cables connected from the flash ADC to the patch panel [8] - done
  • Test and label 1100 short signal cables - ongoing
  • Tested fabricated modules using LMS [9] - done (need to update the wiki page)
  • Cutting optical fibers and gluing plastic caps [10], waiting for 7600 ft of optical fibers
  • Report from students
  • Refurbished (remove soldering bumps and rewrap) 42 modules. One more layer of the detector will be installed today.
  • Need to wrap and fabricate about 30 modules using newly received crystals (will replace some already existing modules with low-quality crystals). Plan to finish with this during next week.
  • Preparing optical fibers for the LMS
• Testing of PMT dividers -- Sasha / Vlad
  • -Tested 6 dividers from the first batch. Asked to produce all remaining dividers. Expect to receive some of them in a couple of weeks
• Proceedures
• Installation of the FCAL2 detector & integration to GlueX -- Sasha / Arshak / Vlad / Hakob
  • Detector installation [11][12][13]
  • Detector installation page
  • Updates from the meetings with Tim's group [14]
  • Discussion of the FCAL2 installation procedures [15]
  • Final mapping of low-voltage cables
  • Mindy continues with wrapping crystals and soldering wires to sockets.
  • Projects for summer students
  • Summer Students (2023)
• Light monitoring system -- Arshak
  • lms_update_09_28_23.pdf
• Analysis/Simulation
