The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

My 200KV Marx generator ran for the first time today, and it worked perfectly. Being a little "cautious", I set the spark gaps for only 1.25 inches and ran a ballast made of 2000 watts of halogen bulbs to limit the current to the 40kv potential transformer.
My goal was to separate amethyst crystals in one pulse, a process that takes an expert with a tiny hammer several hours. The project was a success.
My 200KV Marx Generator and rock disaggregation vessel.
The result after 1 pulse! Original rock was about the size of a large grapefruit.
Spark gaps only set to 1.25 inches during this test.
The 40KV GE potential transformer and diode string.
Now I want to find some funding to build a backpack version using proper Maxwell pulse caps. Any takers?

There's been some ideas to do high voltage coilguns built into backpacks. For a low voltage version it would be fine, but both designs use the energy stored in a capacitor where energy is a function of capacitance and capacitance. To make it small enough to fit a backpack the caps have to be lower capacitance, higher voltage, and if there's 200kv worth of isolation stuffed in as well, there's really no point to it anymore.
But if you mean something that is built into a backpack unit to be assembled remotely, then go for it!
Nice work though, but don't get too comfortable near those caps XD

Yes, a version that could be traversed into the bush and setup, not a backpack mounted weapon, although that would indeed be cool!
When you say "don't get too comfortable around those caps", do you mean it would be unwise for me to sit next to them while they charge and let the hissing corona leaking from the gaps keep my coffee warm?
Yeah, I stand in the other room when they go boom! Blew out a window from a discharge once, so there is always a risk of shrapnel, even when it's working!
Wow that looks dangerous, no way I would have something like that strapped to my back. Maybe an electro-fishing backpack device could be modified? Some of those electrofishing backpacks are actually powered by small petrol engines!

Looks good! The only suggestion I can offer is to put some big high wattage resistors in series with the two charging inputs, to protect the diode string and transformer from transients.

Thanks for the advice. I wonder what value would be good? Perhaps a 500 watt halogen bulb would work as a charging resistor?
