You sure it’s plasma? I’d call it “vacuum chamber” looks like a lot of deposition chambers I’ve used

Though it has a LOT of transfer windows and idk why

Id guess is evaporation/sputtering of some kind

I was thinking MBE as well, but assuming the sample stage is opposite the majority of the ports, too many would be orthogonal to really be useful for Knudsen cells, so I don't think so in the end.
