Re: Simplified Spherical Z focus, updated spreadsheet

No doubt as a pulse device this seems the best road, the only problem is that it requires a huge inner grid radius compared to the outher shell radius, unless you allow the differences in voltage to be very high.

Re: Simplified Spherical Z focus, updated spreadsheet

2 microns seems a bit optimistic for the focus to me...

Re: Focusing the beam by using differential velocity of the ions

<t>Alternatively you could use a multi-MHz beam buncher to do the same thing without having to try to modulate the voltage right. Problem with these strategies is that it requires either a long drift space, or large energy differences in the ions for them to converge in the center if you want reason...

Re: Has anybody tried replacing the grid with a target?

Yes, that would be a problem for anyone close by, but all in the name of science!!

Re: Can sonofusion derived neutrons make cheap Am 242-m?

Also, when U-238 captures a neturon it will decay (in several steps) to Pu-239. This can then be used as a fuel. This is how the CANDU reactors work.

Wow, you weren't ambitious enough if you completed your years goals in 2 months....

Re: Fusor + Mirrors = Laser and less wasted energy?

Oh definitely, agree on the fact that reflectors are ppor at best. I was just chiming in that theres no need to even think about Be when C works as good, if you need a neutron reflector.

Re: Fusor + Mirrors = Laser and less wasted energy?

For the amateur, plain old graphite is almost as good as beryllium, but cheaper, easy to work with, and non toxic (within reason)

Re: It is either stupid or brilliant. I have not decided.

<t>The way you worded your first post was poor then because you say nothing about time varying field strengths...<br/> <br/> This would work, but the velocities that the plasma could attain would be minimal compared to if those same deuterons were accelerated with a voltage potential. Also, you woul...

I believe its all Great Britain, but I could be wrong.
