How to obtaine 90KV and 80 KV with a 90KV HV power supply?

Post by steve_rb »

I need to connect 90KV to the target and I need another 80KV to be connected to electron shield around the target to collects electros. I need to know how to obtain this 80KV from the 90KV power supply I have without having to purchase another 80KV high voltage power supply for this purpose. I have seen in some papers people have used Zener diode for this purpose but I don't know how this works and which Zener diod (specifications or part number) I should use.

What is the current? And is the currect always it the same direction?

For a simple solution, just put 37 of these is series:

Makes a 10kV 100W zener, isolate the whole string.

Steve,

I'm curious why your post is exactly the same as the post made by a user yesterday who is, and has been, banned on this site for three years. There's nothing wrong with the question (though I'd argue it is a HV question, not a fusor construction question), but there is something very odd about seeing the exact same question come from two accounts in two days.

Explain yourself.

In spite of the help offered above, which I would be loath to try, I don't think anyone here has "played" with such voltages as you note in the fusor arena. These levels create a high degree of risk and complication, if any real energy capability is behind them.

I must agree with Carl. What are you doing and what is your effort about here. We are a bit leary about folks trying to work around being banned for misuse of the forums.
