Difficulty level of adding SiO or SiO2 overcoating?
|
Someone proposed that I investigate how much it would cost, both time and energy, to add on the capacity to do overcoating (i.e silicon monoxide or dioxide or MgFl or whatever) to a late-1960s Electrodynamics corp vacuum chamber with bell jar that right now just does bare aluminum.
I know my predecessors tried and failed; they
were a lot better at electronics than me. I've looked it up in the past in various printed and online sources dating back to the 1950s and I'll admit I'm intimidated. I don't recall any details though. Sounded like the hardest part is determining when you have the right thickness, and you have to use all kinds of weird and strange tricks do determine that thickness indirectly...
Anybody done this? How hard is it? What extra devices did you find that you needed?
Thanks so much for your help in the past. (Our chamber has been doing pretty well for a while now.) ? Guy Brandenburg, Washington, DC?
