Cryotubes? Cryogenically Frozen valves

Yeah, there's at least some data for martensites, albeit ambiguous. Not much of that used for tube cathodes...

I wonder about that "Vacuum Enhancement Procedure"...

Bake them in an oven?

You can say THAT again...

You turned me on to Chris Hitchens bio... cool beans.

I'd want to Google Scholar that statement -- I think you can polish thin metal films cryogenically.

Of course materal gets a smoother surface when cooled down. The thermical movements in the atoms and molecules stops at 0 Kelvin which would prevent the surface from being bumpy and bulky due to elementar particlas bumping and jumping causing lumps on the surface.
