Re: Need some help

Hello Steven, It would be more easy to understand with a diagram. All this is a bit fuzzy. I understand that you want to create a "Biconic cusp" (2 solenoides with an inverse current so magnetic fields in opposite direction). I suppose that you are going in some way not described, to inject a plasma...

Re: Fusor without inner grid?

Hello John, Thanks for the information. I agree that the diamagnetic field can be neglected, but the space charge is fondamental if your plasma is not neutral and I think it's the goal here to dissociate D2 molecules in ions. The space charge is an expanding pressure which is in equilibrium with the...

Re: Successful Completion and Operation of the Integrated High Vacuum Test Stand and Micro Propulsion Testing Chamber

Hello Michael, Thanks for your complete answer. It's not really for a Fusor but I study (by simulation) the following problem: when you inject electrons (to get a negative potential with the electrons cloud) in a set of magnetic mirrors (to avoid the "cusps" of the "biconic cusps" devices), if the e...

Re: Successful Completion and Operation of the Integrated High Vacuum Test Stand and Micro Propulsion Testing Chamber

Hello Michael, >It's really a shame there isn't more effort on pulsed fusors. Speaking of pulse, do you know what are, at the moment, the approximative minimum limits of time during which a pulse can be controlled (microsec? nanosec?), and precisely: * in case of a magnetic field pulse, what is the ...

Re: Columbus-I Pinch Tube Build

Thanks Rex and Mark for both links (abstract and 70 Mbytes PDF). It seems interesting and a lot to read.

Re: Columbus-I Pinch Tube Build

Mark,

>I cant locate a non-pay link to the document and the pdf file size exceeds the limits of the forum.
Anyway thanks. It is not that important. If, possibly, you have some abstract (of limited size), here is my email: f6cte at free.fr

Re: Columbus-I Pinch Tube Build

Hello Mark,

Have you a WEB link about a description of this pinch tube device, at least to understand the posts.

Thanks

Re: (Clueless where to put this) Would this generate useable energy?

Hello, TKS Andrew for the interesting link. So the problem is a 3-bodies problem, with electrostatical forces replacing gravitational forces (both in K/d^2). However why such configuration of forces balance would supply useful energy would deserve some explanations by the author of the idea. Patrick...

Re: (Clueless where to put this) Would this generate useable energy?

Hello, I try to read your image but it is a bit difficult ☺. However I understand that: * two particles rotate in a different orbit (through, i presume, some vertical magnetic field), * one particule goes up and down (with, I presume, the help of an electrostatic field which traps this particule). L...
