Re: [TCML] Large Plsma Tube

["resonance" <resonance@xxxxxxxxxxxx>]

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.
