Sorry for the late reply, I've been really busy the past couple of days. Basically, it was supposed to be just two ideal solenoids, one inside the other, each generating a magnetic field of equal strength. Therefore, they would supposedly create a region of no B from 0 <= r < r_inner, and...

Sure, here you go (sorry for the yellow - on - white, its the only full marker I have at the moment):

(NOTE: this is assuming trapping in 2 dimensions, with "axial" referring to a third orthogonal to both) If there are two nested (ideal) solenoids of equal strength, pointing different directions (i. e., generating internal magnetic fields 180 degrees off from each other), then presumably they...

I had another idea for this: an electrostatic paraboloid surface, to make the trajectories of (most of) the alpha particles parallel. I know it wouldn't be useful directly as a classic z = x^2 + y^2 shape, but I'm still trying to figure out exact what form in would take. At the edge, even though...

The ultimate goal for a machine like this would be to provide an alpha particle source without requiring nearly as many radionuclides, and without needed as much energy (as they already start off at several MeV from the reaction). Any source needed could be smaller, as each next "step" in flux...

You certainly have good merit behind your considerations. I also figured that the moderator would interfere with the alpha particles, which is why I wanted to focus them into a beam first, such that they could be redirected and focused back to the core through a narrow hole instead of simple...

Wow, thanks for the detailed reply! To answer your question, it was supposed to be for a concept I was considering - chaining together (a, n) and (n, a) reactions, along with a constant input source as a method of high alpha flux generation without requiring much power, or being able to power...

Thanks for the resource - I haven't come across that one yet. However, it seems mostly concerned with point sources in 2D, and only capturing the emitted particles with a very particular range of velocities. I've been trying to figure out how to do so in 3D, and how to capture as many of them as...

I think I get what you're implying: A magnetic field akin to that produced by a current wire, running circumferentially to an axis, with all emitted particles except those exactly aligned to the axis returning in a loop back to the source. How could you then, say, boost them? Would that require...

I don't think the way in which the field varies matters too much (as long it's not, say, a jump at the very end). This sketch should help:

I'm posing this question because it seems like it should have a simple answer, but I can't for the life of me figure it out. It seems a setup like this could be very useful; if there were charged particles inside, and the magnetic field was stronger going from the center to the shell radius...

Thanks for the reply. I've considered something along those lines, but the issue I always stagger with is the particles with velocities off-plane (the "plane" being defined as the one with the homogeneous field as its normal). Wouldn't they spiral away from that source? Forgive me if there's...

Basically the TL;DR. I was entertaining the idea of some sort of device as a challenge, but I couldn't think of a surefire way to capture as much of the output of, say, a collection of radionuclides, and direct the output charged particles back into them, while being in a form consistent and...

Thats fairly interesting, Ill have to look into that. Maybe ot can also provide additional insight
