Re: From confinement, to jet mode, and star mode

Thanks for sharing Richard, those SIMION plots in the link you sent are very telling for why the edges of the stars form. My guess then is that "jet" mode comes as a result of asymmetrical positioning of the inner grid (so the electric fields lines are less "concentrated" on one end than the others,...

Re: COMSOL simulation of a FUSOR?

I don't think COMSOL has a module to do particle tracing unlike SIMION. I know for sure you can definitely run an electrostatic simulation to see the spherical E-field patterns - the usefulness of it would really then be the ability to just see the E-field patterns for different CAD models of inner ...

Re: Fusors and Maxwell's Equations

Here's my take on it - it has the potential to be a GREAT educational tool, only if people allow it to be. I got funding from my university to build one demo fusor for educational purposes. So, I wanted to use fusors to demonstrate the concepts of spherical capacitance, electrostatic fields, electro...

Re: From confinement, to jet mode, and star mode

Ah, so if it relies purely on the geometry, then jet mode arises as a result of the "asymmetry" of the alignment of the inner grid? Since in reality we can't have something that is purely right smack in the middle; a little bit off centre and we would see electric fields weakened in one particular d...

From confinement, to jet mode, and star mode

Has anyone had any success in explaining the mechanism for how the fusor eventually transits to jet mode or star mode ultimately with a low enough pressure? Does voltage play a role? I would love to hear someone point me in the right direction to understanding this phenomenon, thank you!

Cheers
Sam

Re: Sale! 30kV Supply, Neutron Flux Tubes, and Vac Equipment!

Power supply is sold out!

Now selling only the neutron flux tube, a bunch of other vacuum peripherals like tubes, clamps, and an ISO100F open flange with the O-ring!

Neutron Flux Tube ongoing sale for $500 USD
