HV- voltage multiplier circuit confirmation needed

[wings]

With regards to the multiplier pictured, what kind of rating do those capacitors need to be?

for the big generator all the informations below the picture.
for the small ion generator see this circuit that have also resistors current limitation.

Danger high voltage !!!!

Hi All,
I'm trying to make a new voltage multiplier board for one of my power supplies so that I can get negative HV from it instead of positive HV. I've attached a drawing of the simple changed circuit that I think will do it below but I'm not an electronics expert. Can someone who knows better tell me if I got it right? Note, I used electron flow instead of conventional current since that's the way I think.
Thanks,
Steve

PS. It's for my Hyde generator project:
http://rimstar.org/sdenergy/hyde_generator/index.htm
It's basically a big capacitor with rotors and stator in between the plates. Previously I was using HV+ on one plate and ground on the other. I want HV+ on one plate and HV- on the other instead. I'll use separate power supplies for HV+ and HV-, both relative to ground.

@Steven
Your circuit looks okay to me.
I think the same way in terms of electron flow, too.
Question:  Did you do that to your finger in the picture?  Your finger?
@all
Try and watch out for your body parts when using high current levels around Cockroft-Walton voltage bridges/multipliers.

Take a look at this:

In really big systems, very high value resistors(1 megohm) can be paralleled with the capacitors.

Also,

A certain amount of balanced resonance should be needed for proper component selection.

Thanks Lee. And that picture was from @wings, his finger.

Hi Guys,
The new HV- multiplier board went pretty fast but it took me a while to document what I did. It works great though. I did only a single stage because I wanted to get as low as my power supply could put out so I can get as low as -1.3kV. I don't know what the high end is.

My purpose in doing this was so that I can charge up a capacitor with HV+ on one side and HV- on the other, instead of the usual HV+ to ground. So I tested this new board/power supply in combination with my 30kV positive power supply. My test had -1.4kV from one PSU with +1.84kV from the other PSU for a potential difference of 3.24kV. However, both the variacs I have for feeding the 30kV PSU are sometimes arcing inside causing unwanted noise in the HV output. So my next step may be to use a single PSU with two outputs, a HV+ and a HV-. I looks easy enough to do and I have just enough parts left for it (always buy more than you need.)

Anyway, the full details with photos and scope shots for both the negative mulplier board and the combines HV+/- testing are at:

Thanks for all your help. I'll update you when I have the new dual output done. After that I can revamp my Hyde generator and test.
