Re: Proposal of a new type of colliding beam fusion reactor which electrical gain is superior to 1

Hello, This paper had a big weakness, i.e. I supposed that the magnetic corkscrew device will permit to keep the radial characteristics of the beam, based on the patent . It's a common problem for colliding beam fusion reactors, i.e to prevent the beam to thermalize (even at a certain energy cost). ...

Re: A Thought Experiment on Ideal Conditions

Thanks for the explanations. >in a final system the losses can be minimized from the electron beams by slowing and recollecting the electrons after they pass the centre. However, due to successive yields, you will recover perhaps 1/3 of the primary energy as a maximum. It seems difficult to do bette...

Re: A Thought Experiment on Ideal Conditions

Hello, Thanks for the interesting document. I looked at your main diagram and I hope that I undestood the principle. It seems possible to create an electrons cloud in the A zone but at a price of an enormous electrons injection power. Each electron is injected with a yield of 0.5 for a good ion gun ...

Re: A Thought Experiment on Ideal Conditions

Hello Storm,

Just to make you know that your PDF DirectElectronBeamInertialElectrostaticConfinementNuclearFusionReactor.pdf is unfortunatly not readable here, for an unknown reason. Perhaps, I'm not the sole person to have this problem (?)

Re: Low energy (<100eV) ion sources

Robert, Here are some rough ideas. You can: * force the emittance to a weak value, passing the beam through a calibrated hole. Of course you will lose many ions, * use a serie of electrostatic lenses to make converge the beam : http://f6cte.free.fr/Electrostatic_lens_sizing_Rev_B.pdf This will limit...

Re: Low energy (<100eV) ion sources

Hello Robert, >the slower the ion, the smaller the Larmor radii, so the lower my magnetic fields have to be to prevent the ions I don't know your configuration, but the Larmor radii depends on the initial ions radial speed. If you limit the source emittance by limiting the beam to a very small angle...

Usefulness of the magnetic « corkscrew » for particles beams

Hello to all, Here is a small paper about a device ( the magnetic "corkscrew" ) which intrigued me, as its use for particles beams was not very clear, even after having read several articles. So I tried to describe this device and its possibilities. Here is the abstract: This device is mainly used t...

Re: Fusor theory variant on arxiv.. EV Tsiper

Hello to all, I read this interesting paper. It is based on the main hypothesis that two ions of the same mass and the same speed colliding head on keep their energy (without any energy exchange) but change of direction (with probably small scattering angles). For more information, see the Appendix ...

Re: Proposal of a new type of colliding beam fusion reactor which electrical gain is superior to 1

Dennis, About interactions between particles (electrons and ions), I'm relatively confident on my calculations (and simulations). However, it's true that it must be not so direct because first tokamaks confine plasma 0.01 s or less whereas the last generation confine about 100 s. Moreover, I have no...
