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

Hello Steven,

I just finished to read the two very interesting topics about your FICS apparatus.
One thing astonished me is this original way to recover part of the kinetic energy (even if in your device, you recover a very small part, but...), by electrostatic influence, the energy E recovered being equal to (if I follow you) E=Q.delta U (with Q the Coulomb charge of ions colliding the cathode and delta U the potential "climbed" by the ions).

I don't see this way using a Zener (note that I ignored up to today that such Zener could exist) in the various "direct energy conversion" systems (kinetic to electric here) on the Net. Is it a known system or your invention?

Patrick
I introduced Steven to making these high voltage zeners from Transil diodes
These diodes exhibit extremely low leakage ie femtoamps so they can be used for self biased electrodes (such as secondary electron suppression and einzel lenses) and i have been using them for 15 years to provide the anode cathode potential for an ion source elevated to the anode potential above earth.
So a 3000 volt zener made from Transil between anode and cathode of the ion source but the anode to ground voltage is 120kV so I can run a system with only one power supply that does the ion source and accelerating potential at the same time --especially useful for anode layer source type ion sources but it also works for cold cathode penning ion sources as well

Clever system. Thank you John. Is there some document in the Net about this system and these Transils (I knew Transils but as protection of electronics, not to provide differential voltage)?

Patrick,

John is correct, using TVS diodes is preferable to Zeners (although both work fine) , and in my next build I will use Transil Diodes.

TVS diodes are a way of demonstrating my invention, but energy is turned into heat in the diodes, so to recover AC electric energy you need a reverse Tesla coil with a tiny spark gap at the top, that will bleed off and carry electrons to ground via a high impedance coupled coil.

I am quite pleased with how my rig is working at the moment, and I have discovered something rather interesting, the FICS reactor seems to be directional i.e. non-isotropic emission. Neutrons beam out top and bottom.

This discovery has led to my new invention, the SUN (Slingshot Unidirectional Neutrons) I hope to build one soon (image attached).

There are a few secrets inside, but I will let you guys speculate on that ;)

Steven,

When you say top and bottom do you mean the same axis as the ion beam? And what ratio do you observe (2:1, 10:1, etc.) ?

Joe,

Yes of course..., Newtons third law right?

"For every action there is an equal and opposite reaction"

If the alpha particle/proton can only go to ground via the tube, then the neutron can only go in the opposite direction right?

This is all pretty obvious now, but it has taken me since 2005 to figure this out, I have over 2000 posts on fusor.net to prove it ;)

Steven,

I disagree. The alpha is at 820 keV, much higher energy than the potential well so it can travel nearly any direction. Even if that wasn't true, the initial velocity vector could be in any direction.
