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

[Robert M. HAMILTON]

Michael Young,

I'll presume you have identified  a cerium compound that disassociates in
vacuum, at a reasonable temperature to yield metallic cerium. I have not
researched the literature. I do know cerium is used in photocathodes and
when I made photomultiplier tubes I routinely evaporated cesium and
antimony in situ using dispensers made by SAES, Italy. They also had barium
and mercury dispensers. If you have not ID the precursor it might be worth
contacting SAES.

Regards,
Bob
