I predict/guess xray/gamma rays problem in larger polywells

Post by wacker.popeln »

THe stronger the fields
the larger the electron cloud
the steadier the fusion
the more fusion fuel (p-b or worse)

the more gamma and xray will occur due to destructed electrons.

What do you guys think>?

HOWMUCH ist hte question.
anyone an idea?

I think you don't understand p-B11 fusion. No electrons are created or destroyed in the process, only protons and neutrons rearranged. The major gamma sources from p-B11 fusion plasmas are:

- high energy electrons bouncing off boron nuclei, reduced in a polywell by electron energy being less than boron ion energy, and annealing reducing the high energy tail.

- fusion product alpha particles hitting boron nuclei, reduced in a polywell by the alphas escaping the reaction zone fairly quickly.

The softer gamma emissions from alphas hitting the outer chamber walls are greatly reduced by direct conversion collecting most of the alpha energy.

Ahhh, no.

X-rays wont be seen at any significant level (Bremsstrahlung).

Slow electrons that are dense should not be creating any real Bremsstrahlung.
I like the p-B11 resonance peak at 50 KV acceleration. In2 years we'll know.

exactly

in a larger electron cloud we add also hte proton (hydrogen) to this
and increase hte numbers by densities of electrons and amount of boron nuclei plus amount of hydrogen protons

and amount of created helium nuclei (alphas) hitting more boron or electrons

is htere any calculation or prediction how much htis will increase

(!)
hard radiation cumulates/ activates materials. espec metals. when is the wall and coil radioactive
or coolant possibly
