Re: Some Diffusion pump Questions

Coax cable provide a safety ground. Intrinsically safe, and for modestly high voltage good coax is often much cheaper and more available than High voltage wire.

You need to really understand high voltage systems and related safety - issues such as proper (fail safe) chamber grounding, properly ...

Re: Precipitator power supplies?

... Of course, the diode as you may or may not know is seeing a higher peak voltage than the max rated voltage for the supply (for any AC powered device) so these diodes must be rated for the higher voltage with some safety factor. As for grounding, that is an issue but that depends on the supply ...
