Dear Peter, Dear Claude
the measurements at -90C is suitable for us. All my suspictions we can close during simple test. If we will organize circulation with dummy TPC and after some time when the humidity will be more or less stable (2 days) and after that we have to measure the dependence as function of the pressure. If we have linear dependence everything OK.
I do not know the complete designg of device 373. It has own flow controller and the pump. I did not understand:
-this device return or not hydrogen in the system? Perhaps it simply throw away the hydrogen?
-I do not understand... In principle, with flow controller and pump they have possibility to stabilize the pressure in the gold mirror area. In this case our recalculation to 10 bar is impossible.
So, main question. If they have massflow controller BEFORE the mirror and low pressure near mirror this device is not suitable for us.
With best regards Sasha
These questions are principle.
