Revision as of 20:00, 7 April 2022

Meeting time and location

Preparation for mass production of FCAL2 modules -- Sasha
- 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]. Pre-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.
Module fabrication -- Sasha
- Modules fabricated by Arshak and Sasha (list on Google Drive) (grand total 245)
- Fabricated modules in TEDF
- Status of fabrication
Light Monitoring System -- Arshak
COMCAL tests, TAC running, etc. -- Sasha
