This explains the Vircator quite well...

I do not think so. Wiki is very useful and also in this matter but there are not graphs and do not explain how to make inos go through anode. My proposal is a way to do it, but I do not know if it is the better way.
Is more fun to test it!

In order to use it in a real fusion experiment I would need a 240kg C-4 vircator

It explains the concept not its intricate workings....

Hi.
I have failed to see how this has a non destructive purpous, Fusion.
I want to know what you're using this for.
This also apears to be in the wrong forum.

Kolas: I moved it to EM Radiation since it seems to be more or less about EM weapons/HERF.

I think vircator tubes and FCGs are acceptable topics of discussion for 4HV, and I'd be happy to see this thread develop into a discussion on whether it's feasible for hobbyists to build the things. After all, 4HV is where Slava hung out when he was making his HERF guns and giving talks at hacking conferences.

However, please remember that we don't like discussion on kinds of explosives that it's illegal for Joe Public to own.

I found my post! it thought it was deleted.
Well I read that it is possible to build a reusable Vircator.

In Spain it is legal using some explosives if you have the authorities forms. In my job I tested them.
In order to test it perhaps it is possible to tests before by using a spark gap to simulate explosive.
I would like to make modifications to vircator to a reusable ultra very powerful and short microwave pulse in order to use it in fusion experiments: It is very difficult to couple energy to deuterium-tritium, because it rejects it. Laseres waste too much energy and breaks, so I think microwaves are perhaps the only way.

I think that an E bomb work:

E=1/2*L*I^2 Then if you inject a great current, it will be stored at the inductor and then if you collapse the inductor L->0 so I->infinite as long as E remains constant

Vircator uses this another way:

E=1/2*C*V^2, then if you collapse the capacitor, then youwill have C->0 and V->infinite

But in both equations I do not find that explosives increases the output power, they only shortens the pulse, but the area must be tha same

Fusion researchers do actually use microwave beams (and lower RF frequencies too) of several tens of megawatts to heat their plasmas up. "The Science Of JET" describes the various heating systems they use quite well:

VERY GOOD! I will need some days to digest so lot of information

Some megawatts is possible for some milliseconds by using capacitor discharge to vircator or perhaps is better to build a very little vircator-tokamak by making a torus using a coil folded as a torus, injecting a hot plasma, 10Megaamps to the coil and then making a big implosion. I think I could make IGNITION. But If I am success I would have a little thermonuclear explosion of about 100 kgs TNT equivalent level, so I can not make it in my apartment and my wife would be unhappy, so better make it without plasma (at the beginning). But the problem if how to measure the magnetic field B. RF power can be measured by using an output antenna, but I do not how to measure so close chirp

Some of the world's brightest scientists and engineers have been working on ignition for 50 years, spent billions of euros building tokamaks the size of basketball courts, and haven't managed yet. If someone ever gets a fusion reactor to ignite, it would have far reaching consequences for everyone's lives. Using fusion power, we could probably leave Earth and colonise other planets.

So if you think you know something these guys don't, better apply for your Nobel Prize now!

Or you could try calling up one of the guys at ITER to discuss your ideas and see how long you get before he hangs up.

I do not know any ITER person and I do not like waste my time trying speak to that busy fellows and I do not want any nobel price, because I make my magnetics machines for fun at my free time

. I think that amateur projects can be interesting if it can be built high efficiency machines.
After more calculus, I have seen that the right size of the flux compression tokamak reactor may be 12cms diameter that is too much to me now, but I can make another interesting flux compression machines with gunpower, magnets and coils.

Do you know more info similar of JET but about Supra Torus?

Note: I have designed about 30 different fusion reactors, but I would need more than 100 megajoules capacitor bank for making ignition but I am working on making more little ones.
