Minutes

Attendees: Sasha, Igal, Joerg, Malte, Phil, Zisis, Igor, Jane, Olga, Susan, Eugene, Bill, S.T.

Waiting for last 10 Crytur crystals from physics divison
Expect final batch of 75 Crytur crystals in May
Crystal wrapping and wire soldering by Mindy of detector support group continues
Grand total of fabricated modules = 1378
- Starting to move crystals to new area in EEL building
Sasha met with Fernando regarding PMT divider order and other divider details
- 1 PMT/divider for bench tests with/without amplifier: noise test in FCAL dark room, no big issues found
- NPS added RF filter to their divider design due to high noise levels -- not needed for our lower-gain design
- Will order high lead-time divider components in anticipation of full order early next year
- Chris S. to make PCB prototype
- Discussed possibility of replacing unshielded ribbon cables with shielded ones
- Make 5x5 prototype to test in hall during GlueX run in January/Februrary?
- Sasha to work on GW contract, send dividers in February
Student lodging for summer
- Arranging housing through Hall D administrative support
- Need to be aware that ResFac will be booked for Hugs for a couple of weeks (early June?)
