Meeting time and location:
- 9:30 am EST (JLab time) remote only
- Zoom meeting ID: 161 050 9142 Passcode: 004965
Agenda
- Preparation of parts for FCAL2 modules -- Sasha
- Crystals:
- Received 40 crystals from CRYTUR [1]. Remaining 55 crystals will be sent to us during this and next month.
- Wrapped crystals: 15
- Available for wrapping: 10 SICCAS + 25 CRYTUR = 35
- George (DSG group) finished with preshaping.
- More than 400 long signal cables received, can start checking, bundling, labeling (receive labeling machine in a couple of weeks)
- Procurement parts for the LMS
- Ordered 16,400 ft of optical fibers delivered to the lab. 7,600 will be delivered in September.
- Expect to receive fiber donats in a couple of weeks (will start working on the LMS)
- Crystals:
- Module fabrication -- Sasha
- Fabricated modules: Total 1533
- 46 modules fabricated during last week (Madison, Madylin, Hillary)
- Available for fabrication: 35
- 42 modules fabricated using 'low quality' crystals for the stacking mockup and 'crunch' tests.
- Report from students
- Fabricated modules: Total 1533
- Testing of PMT dividers -- Sasha / Vlad / Arshak
- FCAL2 modules with dividers installed on the CCAL [2]
- Met with Vlad P. on Tuesday. Fine tuned the divider circuit. Checking/tuning an amplifier; Chris S. ordered some OPS.
- Installation of the FCAL2 detector & integration to GlueX -- Sasha / Arshak
- Detector installation page
- Updates from the meetings with Tim's group [3]
- Discussion of the FCAL2 installation procedures [4]
- Final mapping of low-voltage cables
- Manpower and division of tasks
- Projects for summer students
- Summer Students (2023)
- Light Monitoring System -- Arshak
