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...

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

Hello Dennis, As far as I know (i.e through my books) the main source of leak of tokamaks (and hence stellarators) is the magnetic field drift (due to the fact that magnetid field is not constant on a section), this variation of field acting on the ions radial speeds (by separating particles before ...

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

Hello Richard, Thanks for have a look. About the cost, I think that a colliding reactor (as Fusor and others) is much cheaper that a Tokamak because you have not to carry a plasma to 100 mlllions of degrees (or more) through different complicated ways. Instead you use particles injectors. A neutral ...

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

Hello to all, For the ones interested by new proposals about fusion, here is an article about of a new type of colliding beam fusion reactor (at principles level). It can be downloaded here: http://f6cte.free.fr/Proposal_of_a_new_type_of_fusion_reactor_using_a_non-thermal_neutral_plasma_Rev_A.pdf Ab...

Electrostatic lens sizing

Hello to all,

For those who need to size electrostatic lenses, the following paper can, possibly, be of some interest for them:

Re: Efficient way to bombard target with electrons in the 50-100 eV range? (not for fusor)

>does the the "positive" terminal of the filament need to be at -100V and the "negative" terminal at >-85V? In my opinion, strictly speaking yes it will better to have around -100 V (so to not disturb the electric field), but if the filament is very small compared to the anode and the cathode, the e...
