The goal is to assemble 450 - 500 modules by the end of summer.
64 CRYTUR crystals available (checked) 250 crystals produced by SICCAS, will be in the lab in February
100 PMTs are in the lab, expect to receive 400 more by April.
- Checking crystals
- Visual inspection (5 min per crystal)
- Dimension measurement (10 min per crystal)
- Transmission check (20 min per crystal)
- Light yield (20 min per crystal)
- PMT checking
- Diameter check
- Check gains (perform check on some randomly selected sample)
