It discharges kind of like a marx generator, too.

I've got a theory:
Because the diodes fail, the caps charge kind of like a CW, but to an even higher voltage. Then, while the initial voltage is quite low, when shorted out, there is a strong release of energy at 8000+ volts. And I also learned that the larger the capacitor, the higher the voltage, but adding more stages decreases the voltage and overall power. And this can't charge capacitors.

Can anyone tell me why this happens??? Please help!

Best CW multiplier I've ever seen! I have a question, my CW is a much lower power, lower voltage model. It runs directly from 120 volt mains. It is a 2 stage multiplier I made with some 1N4001 diodes and some mylar an ceramic caps.
1st stage: 2x 1n4001 diodes and 2x 230000pF Mylar caps.
2nd stage: 2x 1N4001 diodes and 2x 0.005pF ceramic caps.
The diodes are rated at 50 volts repeatitive reverse voltage, and, for some reason, they don't fry. :S
The output of this "voltage doubler" is ~875v.

this is absolutely beautiful. well done.
-
thats bad ass ! nice job
-
Nicely engineered. I can see that I will have to build one now.
-
He must keep to 50/60Hz because of the 1n4007's . They won't work for higher frequencies as they are slow diodes.

Excellent Work!
The Arc frequency seems quite low.
Is this due to the value of the capacitors or the configuration of the circuit?

The limiting factor is the power source. It is based on car ignition coil which can't be pushed too much (here it sucks approx. 200W from the wall plug-in which five times more than what it is designed for...)

Bloody hell... Seriously, with that much work and effort put into it, why don't get yourself a descent NST? I strongly suspect it'll be worth it...

NST is 50-60Hz device... You need much higher freq to drive my CW, otherwise the caps would have to be huge - check the theory on wiki...
