This is an analysis of an 11kV High Voltage Power Supply that apparently exhibited evidence of a corona-induced short in the high voltage connector.

You know how the internet is....down the rabbit hole I went, and, well, one thing let to another, and before I knew it, I came across even more design practices from NASA.
As for researching TWT power supplies, I was looking to confirm guidelines for specifying high voltage diodes. I seem to recall hearing that diodes are susceptible to damage on the high voltage end of the multiplier because of arcs from the tube. TWT PS typically run hot and fast, and unless a diode has sufficient reverse power capabilities, it could spell trouble.
