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 all 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 all remaining (500 ft) optical fibers [12]

- glue plastic caps on all fibers [13]

Testing of PMT dividers -- Sasha / Vlad
- - Received all divider PCBs. Preparing test setup. Will proceed with testing during next week
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
Analysis/Simulation

Attendees: Phil, Igal, Zisis, Liping, Sasha, Vlad, Jane, Jon, Olga, S.T.

All remaining optical fibers have been cut and donuts attached
- Still need polishing; Sasha to get driver from Arshak to use polishing machine
- Design for LMS installation to be finalized within about a week
Received all PCBs for PMT dividers
- Will proceed with attaching sockets
- Each PMT divider will need to be checked
Installation of FCAL2 modules almost done, only 3 rows remain
- Found and put aside 2 modules with lost PMT vacuum
Sasha working on keeping detector support group involved, also hope to get help from fast electronics group
Liping's proposal for symposium at April APS meeting was approved
