Meeting time and location
- 9:30 am EST (JLab time) remote only
- Zoom meeting ID: 161 050 9142 Passcode: 004965
Agenda
- 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
- PMT selection
- Module fabrication -- Sasha
- Light Monitoring System -- Arshak
- COMCAL tests, TAC running, etc.
- Data analysis
- Simulations
