I know that a flyback is not the most efficient method but my question remains could I use the flyback from information unlimited. Even if it can't hit 60ma it must be able to hit 10 to 20 ma lower on a high power zvs driver. Remember I am not trying
to set any records with this project I just want to be able to produce neutrons as a learning experience for me.

In my opinion your question has been answered already and you don't seem to like the answer - if that's the case, go ahead and try it, nothing is going to explode.

Okay i'll wind my own and see how it goes.

Let us know!

Just to show you that the flyback isn't necessarily the cheapest/best option, find the core for a high-power SMPS core here with some other stuff I've been considering for voltage measurement, rectification, etc.

I already have a flyback core from an old tv 70s vintage

I have purchased the flyback off of information unlimited it is actually just the windings not the ferrite, I supplied a ferrite of my own. My question is I am pumping electricity via the zvs driver through it and I am not getting anything out. Could it be a bad ferrite I noticed that the ferrite had not worked with any of my experiments with winding my own flyback. I tested the driver with a dc flyback and it still works fine. Any ideas?

Also can you measure current with a HV probe connected to a DMM?

Based on the truly minuscule amount of information you have supplied, it could be absolutely anything at all. Ask yourself if the questions you're asking are likely to generate answers specific enough to be useful to you.

Hello I apologize in advanced for my lack of detail. I have experienced that my flyback is not giving me one little spark of output even with variations in capacitors and the inductor in the driver, so I found this on the webs http://www.easternvoltageresearch.com/f ... ver20.html the high power version says it has variable input up to 100v and variable voltage control and frequency. Do you think that the high power version would be able to give me approx around 10kv and within 10 ma of 60 ma that the flyback is rated for? Also I am curious about using RF amplifiers to do fusion?

Hi Isaac Boehm
If you could get your hands on 15 second hand Microwave oven transformers, add two stage recifered, you could use the below diagram with salt water instead of air, and have each of the 10 cells connected in series, with one MOT driving one cell, you could reach 30-40kv at 100ma.
Just a idea.

Thanks. Ill think about. The thing is I am not very fond of MOTs and have sort of made vow not to use them due to the danger factor. But thanks for the input though.

You could use two NST for 30kv 30ma or four NST wired in two series two parrellel for 30kv 60ma, the four NST would set you back around $1200 new.

Or I could use a 12kv 60ma nst connect it to a tripler and get 30kv
