@pstudier: perhaps, but a high-potential toroid should create a virtual potential in its center, I think. That would tend to concentrate the electrons there. But then, I guess if the potential were positive, you wouldn't have the negative potential needed to confine the ions. Or would you? It seems ...

magrid configuration brainstorming

What other variations of magrids might work besides a polyhedron? How about two coils parallel, with either same or opposite direction of B-field, or a single coil? The single coil would be like the Levitated Dipole Experiment, except that electron transport outward should be minimized by the charge...

As far as radiation, I second that question! From my limited knowledge of physics, I've gleaned that accelerated charges produce radiation, and so I don't see why that wouldn't apply here. I wish I knew more! Maybe it's just not a significant amount of loss: I think the acceleration that causes breh...

Ok, I have a question about the cusps and the losses. The new pdf on the WB-6 final run states: " From this work, the data showed that the MaGrid transport coefficient (in the simplistic oneterm MG equation) was found to be about 10-20x less than from previous experiments on earlier machines. This i...

Woo-hoo! :twisted: That is a great peice of information. I am much more convinced of the credibility of Bussard's results after reading that. That explains the significance of the "three neutrons" that everyone keeps arguing about. So the probability of counting three neutrons from a much weaker rea...

looks like I'll need to download GSL and learn about it. Seems like it has some pretty powerful functions. So I gather that you go through and use the GSL functions to integrate and find the field strength at a point due to each point of the coils, correct? That's a lot of computation, but I guess t...

Yeah, that's pretty much an electric bomb waiting to go off! :shock: As for inefficiency, the problem is that it bites both ways: not only do you not get that energy, but you will most likely have to struggle to get it out of your machine so it doesn't overheat (just like the situation with the magr...

Whoo boy! Looks like I opened my mouth too fast! :lol: I guess I should have mentioned that I've only just had the first two semesters of C++ here at school. :oops:

I'll see what I can make out; I'll probably have a few questions for you once I figure out what to ask!

Thanks!

Nebel says in this pdf that you can get a pretty high field strength, on the order of 100kV per cm, I think!

Hey, that sounds like fun! I'd love to have a look at the code if you don't mind posting it somewhere. I don't know if I could be any help, but if I see anything I think I can take a stab at, I'll let you know.

energy extraction alternative

I got access to this paper through my school's journal subscriptions: Rostoker, Norman, Michl W. Binderbauer, and Hendrik J. Monkhorst. "Colliding beam fusion reactor." Science 278.n5342 (Nov 21, 1997): 1419(4). Academic OneFile. Gale. 1 Nov. 2007 They had an interesting point about using some kind ...

Great explanation again, Keegan! So the beams oscillate back and forth, and they are centered somehow by the configuration. Looks like that might get around the need to have magnetically-shielded coils. I like that. I suppose that this stuff and POPS is similar to Bussard's work in that they all rel...

This is a really interesting subject to me. I know some C++, but not much else. What language are you using? Fortran? (Does anyone even use that anymore anyway?) Also, how are you thinking about incorporating the electric fields: as interactions between a set of particles that you keep track of, or ...

So what they are doing is putting multiple central grids in (the ones that create a potential well directly) but staging the voltage between them, and keeping them all in their own 'shadows' from a radial perspective, right? I'm not sure how that helps. I guess it allows them to either make a more t...

I agree, that explanation makes a lot of sense. I suppose this same effect would apply to the POPS oscillating approach, correct? Actually, though, maybe for that situation the phase-locking of the plasma already establishes a non-maxwellian distribution?
