What kind of vacuums are you pulling? Are you using an ion pump or just
the oil-diffusion pump? What is your bakeout cycle? What? You are
using it on a CAR? OH! That's very different. Never mind. :-)
Seriously, what I meant was that the stuff was too contaminated for our
use in making electron-beam laser tubes. So it was throw it out or use it
for other stuff. We didn't have other stuff to use it for, so we took
turns "liberating" it. Didn't cost the company any more either way.

Thanks, but there is no real rush. I haven't really looked hard for it in
the Twin Towns. I bet I can get it here. I don't know anybody in Central
Research anymore, and the silicon-chip revolution put paid to the
electron-beam laser project years ago. It's all in our notebooks in the
3M vaults now. The hardware is all gone. That's the research game. I
built 150 lasers for nothing. Coulda gone the other way. The PhD's may
have learned something that they used later.
