I reiterate my earlier comment. I think if you plot your fields you’ll find that the -65 kV penetrates into your center electrode and what you have built is a single beam linear fusor.

Dan,

Thanks again for pointing that out, I am not discarding any hypothesis at this stage. As you suggest it may be operating as a simple linear collider, keep in mind that I have built and tested several versions of simple linear colliders before and found them all to be very unstable, plasma seems to light up on either one side or the other, or sometimes the plasma will oscillate between flashing on one side then the other.

My current triode arrangement seems to work much nicer than the simple diode version.

The physics of what I am doing is really quite simple, so I don't understand why some folks on this forum have such an issue with it. When I create ions at low potential they lack the kinetic energy to climb up the potential well, so the ion density builds up in the core. I don't think it really matters weather there is a beam or not.

But to test this idea I am working on a new core design which does not have an open path through its core. If this works it should eliminate the beam on beam hypothesis. The image below shows a section of one end only. I am doing this modelling in Autodesk Fusion 360 which I find quite intuitive and easy to use.

Maybe the 3D drawings can later be imported into an application like Simion for some PIC modelling.

I have the new chamber modelled in 3D now, so if anyone with access to SIMION wants to give it a go please PM me and I shall send the STP file.

Thanks... Steven
