It would have to be fakeable to more than just me. I expect at least two other independent witnesses on hand. I also expect to be allowed to hook up our own pirani and hot cathode ionization gauges. I'm confident that my level of experience with vacuum systems is sufficient. Personally, I doubt they'll be able to get anywhere near orbital vacuum of ~1e-6 Torr if the sublimator works as they allege. But maybe they have some huge vacuum pumps to compensate for the sublimator sublimating.
Chamber B
Vacuum: 1x10
-6 torr
Pumping capacity: 1 x 10
7 liters/sec condensables and 2 x 10
5 liters/sec noncondensables at 1 x 10
-6 torr pressure; Note: Usual chamber inleakage less then 3 x 10
5 liters/sec of air at 1 x 10
-6 torr pressure
Why can't you find this publicly available basic data yourself?
