Agenda

Simulations/Analysis
Preparation of parts for FCAL2 modules -- Sasha
- Received 100 PMTs (the last batch) [1]
  - All PMTs have been checked (measured diameter)
  - 39 PMTs were exchanged with the NPS (they are slightly tight)
- Wrapped CRYTUR crystals: 707 (15 since last week)
  - Available for wrapping: 722 - 707 = 15
  - DSG group continues wrapping
- List of available parts
Module fabrication -- Sasha
- Status of fabrication
- Fabricated modules: Total 1247 (25 modules fabricated since last week)
  - All SICCAS 576 SICCAS
  - 671 CRYTUR, available: 51
Updates from the FCAL installation meetings with Tim's group -- Sasha
- September 21
- Link to the earlier design meetings
Light Monitoring System -- Arshak

Attendees: Olga, Sasha, Arshak, Bill, Phil, Axel, Azizah, Igal, S.T.

Received last batch of PMTs -- now have 1610 in total + 144 in COMCAL
- Olga, Igla, Sasha did pre-selection based on diameter and traded with NPS
Have 1400 light guides, need 200 more
Have 75 PMT housings (have been annealed) of 300 needed
- Need to check diameters
Crystal wrapping continues. As of the meeting 5 were left over needing wrapping
Expect 105 crystals from JLab pool + 50 more to arrive next month
Week of 10/3, Sasha expects to find time to work on PMT dividers
- Contract with GWU for divider work
- Need to check for possible noise problems seen by NPS (but they are using a higher amplifier gain than we expect to use)
Engineering/installation meetings now biweekly
- Discussing cabling (using thin RG-XX cables (not sure of the number))
- Discussing unstacking and storage of lead glass blocks
- Discussed connection plan for crates for insert
Sasha mentioned need for students in the late spring/summer of next year
