Re: Question: How is the electron not getting into the machi
@happyjack27: magnetic fields can exist within plasma, magnetic field cannot exist in a superconductor. @hanelyp: you mean when more electrons reach the center? The event you're describing is not a steady state effect that occurs when input/loss equilibrium is achieved, because the plasma cannot kee...

Re: Question: How is the electron not getting into the machi
I dont know if I buy that the electrons form opposing magnetic field at the core. I understand, sorta have to talk to people that are more well learned than I am, that charge particles opposes applied B field because in their circling around field lines makes a current loop that makes a oppose B fie...

Re: Question: How is the electron not getting into the machi
I think I figured it out. Consider a conducting sphere, hollow or not, if you shoot electron beam at it, there's going to be flow in the + and - phi direction and + and - theta direction (and all linear combinations of phi and theta). As the current travel in those directions, it should reduce in st...

Re: Question: How is the electron not getting into the machi
According to several of the old time posters to this forum, the plasma can be represented by an image magnet placed within the volume of the plasma. IIUTC, a scaled set of magnets with reversed scale current will act as the plasma would. I asked mattman to include the image magnets several times bu...

Re: Question: How is the electron not getting into the machi
I'm sure Matt only has the coils modeled, which is still extremely useful. It's possible to look at the system from a low beta limit; in fact many drifts are determined solely from B-field alone. I think there are writings on electron density and distribution, I think happyjack mentioned that it's a...

Re:
This is multiplied by the cusp confinement to get the "thousands of passes" confinement of charged particles (electrons)- ie: the Wiffleball trapping factor. What would the electron charge density look like inside the Wiffleball. Is it expected to be evenly distributed inside the Wiffleball or woul...

Re: Question: How is the electron not getting into the machi
hey, a while ago there was some papers about ballooning effects in cusp machines on this forum, can anyone direct me to those papers? In other news, I wanted to write a paper about the sum of all drift velocities in a polywell (like ExB, del(B), del(P), etc), my boss, who's also the professor of the...

electron density and distribution
Hey it's me again, here to ask questions no one can answer.
Does anyone know what or where i can get more information about electron density and distribution in polywells?
I'm trying to figure out del(P) and E.

I see, well that's good that there is detailed theory. okay, I think I may have close to enough to proceed, but not now yet, because I have to do other unrelated things. Anyways, so I was thinking, for every configuration, size, b field strength, and electron gun current there is a max capacity wher...

I was just mentioning the fact that without theory, the experiment can only really determine if square faces are better than circular faces and if higher order is better than lower order shapes. (really if that, because size and b field scaling might not function as we expect, and since very little ...

the 12 face higher order polywell with pentagon faces will have to be compared to the square face one in order to avoid comparing apples and oranges... I'll probably start with just the original design, then square faces, and hopefully if it wont be too bad, then 12 face higher order polywell with p...

looks like I've been ignorant and misunderstood some stuff. I need to be able to visualize the fields of a polywell with primary square loop faces. So to proceed, I can just build 2 of them, one of primary circular loop faces and the other one of square loop faces. While I'm not entirely convinced t...

1. I think I still need to apply some sort of standard. I'll be measuring confinement improvement, and I dont want to comparing apples to oranges. The question is really to ask by what standard across 2 different machines should I use? 2. it may scale like that, but I think there are definitely diff...

sigh... a solenoid does not have zero field at the very center of the ring. B field of a ring of current is just a very short solenoid (actually its more complicated than that, a solenoid's field is all parallel, so in terms of cusps its like a 'plane cusp'? lol) B field vector components sum up app...
