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
- 50 new CRYTUR crystals received
- Need to perform a quality check
- DSG group: preshaping (18 foils a day), wrapping (7 crystals a day on average, expect to wrap 10 crystals per day in the future).
- Contract with the GWU is under preparation (SOW, sole source,...)
- Chris A. continues to braze strips; discussions regarding brazing quality. Bobby preparing soft Iron housings.
- Igal continues cutting ESR / Tedlar
- 50 new CRYTUR crystals received
- Module fabrication -- Sasha
- Light Monitoring System April 1 update -- Arshak
- COMCAL tests, TAC running, etc. -- Sasha
- A 3 x 3 calorimeter will be installed on the TAC platform. Will (can) be used as a TAC run during the CPP experiment and other tests in the future.
- Data analysis
- Simulations
