[labnetwork] Cerium handling for vacuum deposition sources - anyone tried it?

[Robert M. HAMILTON]

Mike Young,
No suggestion because of lack of experience with  cerium PVD. Just thought
I'd share a past resource, with a colleague for highly receive metals. Not
sure what product lines SAES maintains or if there are other resources.
