1. 1 Stony Brook Update T.K. Hemmick for the Stony Brook Crew

2. 2 Now we dry… All the GEMs are in. All the tests are done (twice): –Capacitance while connected. –Voltages on cables. Glove Box being used as dryer: –50 cfm….~1400 liters/minute. –4.5 ppm and falling…

3. 3 Odds and Ends: Schedule: –Dry the detector all this week. –Remove from glove box Monday Oct 9. –Ship to BNL Monday October 16. Flashing the detector. –I personally dont like the LED option: QE at 250 nm is probably dominated by thermal noise. The real test is QE at low wavelengths! –The only reason that we cant flash normal lamps is that Hamamatsu uses transformers. I am 100% certain we can flash a normal lamp. Transformer in base is removable and non-magnetic circuit is easy to design and build. So…put 4 lamps on the detector…put electronics far far away.
