Re: [TCML] Large Plsma Tube





The tube has to be fully vented to the air every time. If you keep a vacuum in the tube it may slowly suck the oil out of the vac pump and into the tube --- a big mess. Ask me how I know.

We usually pump for 10 min and then shut off the valve going to the pump. A second value allows us to bleed air into the tube very slowly with a precision Hoke 10 turn valve. We always start with high vac so the rings are visible, and then go to bright pink which is near atm pressures.

Dr. R is that 14.4 kV 800 mA @ 60Hz? Other than to back bleed other gases, why do you pump down the tube first ( to outgas all thats going to outgas?) and how far?

This is starting to jell in my mind quit nicly thanks Everyone.
