Meeting time and location:

Agenda

Preparation of parts for FCAL2 modules -- Sasha
- Received all 150 CRYTUR crystals from physics division (22-C0275) [1]
  - Expect to receive 95 more CRYTUR crystals in May (835 + 95 = 930 in total)
- Wrapped CRYTUR crystals: 835 (ALL available CRYTUR)
  - Available for wrapping: 52 SICCAS crystals from CCAL [2] [3]
  - George (DSG group) started disassembling CCAL modules and removing LMS caps.
  - Mindy (DSG group) continues wrapping crystals and soldering wires to sockets
- Disassembling CCAL
  - CCAL moved to the ESB
  - All modules (with SICCAS crystals) are removed
- List of available parts
  - Some PMT housing are missing ( > 60, trying to find with Tim)
Module fabrication -- Sasha
- Fabricated modules: Total 1413 (3 modules fabricated since last week)
  - All SICCAS 576 + 3 SICCAS
  - 834 CRYTUR, available: 1
  - Moving modules to the new lab (EEL108)
Testing of PMT dividers -- Sasha / Arshak
- Most parts for dividers have been received
- 25 dividers for the prototype are ready (have to be tested), expect to receive the LV patch panel prototype

during next week. The CCAL prototype should be ready by the end of next week (?)

Installation of the FCAL2 detector -- Sasha / Arshak
- Detector installation page
- Updates from the meetings with Tim's group
- Manpower and division of tasks
- Projects for summer students
- Meeting with the detector imaging group
Light Monitoring System -- Arshak
- 250mkm fiber light intensity
Simulations/Analysis
