Re: Flexible Deuterium Gas Input Hose?

... diffusion flows will be about the same, whether tubing is under vacuum or small positive pressure (i.e. with flow restricting orifice downstream). For the latter case, an upstream flow limit would be good for safety. Then if gas hose popped off at the fusor end, and magically caught ...
