Meeting time and location

Preparation for mass production of FCAL2 modules -- Sasha
- PMT selection
  - Olga checked PMT diameter of 360 newly received PMTs. Many PMTs from the last shipment (210 pcs) were tight (about 40%)
  - These PMTs were exchanged with NPS. 40 more PMTs were selected with Vlad and are ready for exchange when purchase spares.
  - Total number of PMTs: ordered and received: 1510, 140 installed on CCAL.
    - Need to order about 100 (?) spare modules.
    - These PMTs are also used in different test setups
- Production of Silicon cookies
  - Received three fixtures to prepare silicon cookies (42 dishes in each fixture); Olga will take two fixtures to the GWU.
  - Olga produced three sets of silicon cookies during her visit to Jlab. She will take equipment to the GWU today.
  - Contract with the GWU is under preparation.
- DSG group: continue preshaping ESR reflectors (18 a day), and wrapping crystals (about 6 a day)
- Chris A. is brazing brass straps, Bobby is honing PMT housing.
- Igal is cutting Tedlar and ESR foils
Module fabrication -- Sasha
- Modules fabricated by Arshak and Sasha (list on Google Drive) (grand total 209)
- Fabricated modules in TEDF
- Status of fabrication
Light Monitoring System -- Arshak
COMCAL tests, TAC running, etc.
