If cooling is still an issue due to size then I presume running multiple DPFs in series might be an option?

You mean that several pdf with lower frequences don’t get so hot with for a given power output.

Here we are. For a flat coil, which is the nearest kind of coil like the focus fusrion the magnetic field is B=μ*N*I/(2*r). Same figures again but N=1 gives
B=2*10(exp-7)*1/(2*1,0*10(exp-5))= 10 000 Tesla which still is a awful lot. It doesn’t matter how many turns the coil has. Either you take number of turns and current in each of them or all current and one lap, which I did, since sum of current is the only thing I know. I think that such kind of magnetic field, though it’s very strong is also very narrow. It will not change the direction of any ones compass.

The answer is becouse of very high current and narrow distance. Te get an idea of the strength take the formula for magnetic around a wires with a current I. B=I*2*10(exp-7)/(2*pi*r) r distance from the wires. The plasma focus is rather a coil then a straight pinch, but it gives you an idea what magnitude it can be. r is about a few microns and I more than MA. Say I = 1 MA and r = 1,0*10(exp-5) that would give B=300 000 Tessla wich is awful much. Just a very rough estimate.

I hope LPPX soon can afford a better bigger power bank. It would be really interesting to see what a stronger and tighter magnetic field will accomplish.

Cross section is more probabilistic due to particle-wave duality, but basically yes, the bigger the cross-section the more likely a fusion reaction will occur considering there is enough energy to overcome the coulomb barrier.

What I want to know is what and how you calculate it. If cross section is 10 exp -20 what does it means. An very simple calculated example is enough for me to understand I think.

Thanks
That is what is going to happen mechanically and how you going to achieve more amps.
I’m also interested how the process will improve with higher amps and lot of that had been said but one thing is not so much explained and that is about the X rays. What I read and heard the X rays emission could also be reduced, but I don’t get how.

I don’t understand the first part of how this device works. Laser 1 hit the sample and produce a very strong magnetic field. How can just a laser produce a magnatic field. Is this just nonsense or can someone explain. Rest I can understand, but without the first it can’t work.

[PlasmaLord]

Im picking up an old, but interesting thread here that left me a lot of questions still.

Firs of all wouldn’t it be a lot X ray and even gamma ray from the dense and very hot (near 1 billions Kelvin) plasma in all cases. Thinking about Boron – Proton fusion now.

Second how could magnetic field decrease Bremsstrahlung. The question is closer to, how does stronger magnetic fields decrease number of electrons colliding with ions or be deflected by Ions.
