- 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
- Getting summer students involved in the project. Vaccinated students will be permitted to the lab according to the communication with Brian Hanlon (still to be checked). List of possible tasks
- 60 CRYTUR crystals have been received (and accepted)
- 91 + 40 = 131 SICCAS crystals were moved from the NPS lab[1]. 40 of them have been checked/tested before. Crystals have to be inventorized.
- Chris continues brazing brass straps. Some minor issues with brazing the front flange [2]. Selected bad more than 20 assemblies [3] (can be fixed). Revisited the brazing procedure with Tim and Chris. Chris was sick for a couple of days, some backlog in module fabrication.
- DSG: more than 600 ESR foils have been preshaped, more than 150 crystals have been wrapped.
- Production of Silicon cookies at the GWU [4]. See Olga's report. Contract with the GWU is under preparation.
- Igal: continues wrapping mu-metal foils and ESR
- Procurement of spare PMTs: no price increase [5] (hopefully can order 100 tubes).
- Module fabrication -- Sasha
- Meeting with Tim's group and Fernando regarding FCAL2 insert cables -- Sasha
- Light Monitoring System -- Arshak
- COMCAL tests, TAC running, etc. -- Sasha
- Data analysis
- Simulations
