Meeting time and location:

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 [11].
- Tested and labeled 120 HV cables
- Preparing optical fibers for the LMS

- cut 500 optical fibers [12]

- glue plastic caps [13]

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 [14][15][16]
- Detector installation page
- Updates from the meetings with Tim's group [17]
- Discussion of the FCAL2 installation procedures [18]
- 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
