Sorry that’s not really what I’m asking, and I don’t really understand what “beam” stands for. My questions from post numbers 10 and 12 are what I’m trying to understand – sorry for being thick-headed.
Very short version; A DPF produces a brief plasmoid. As this plasmoid collapses it emits a beam. In a Focus Fusion DPF the beam would be composed of helium nuclei, alpha particles, produced from the fusion of p and B11 in the plasmoid.
The energy total of everything else produced by the FF wouldn’t amount to very much compared to the beam, x-rays and heat.
Vansig said that one-third to one-half of the total output is x-rays. Doesn’t this mean that the output in other spectra would be significant? How do I find the proportions of the various different types of energy outputs? Didn’t they place detectors in there when they were testing it (or is there enough known about this reaction that they could just know all the outputs and their relative proportions)?
Also, are the x-rays all the same frequency? If not, then doesn’t this create an issue for capturing them. I take it this “pulse of charged particles” (loose language in my opinion) is mostly x-rays – but doesn’t it matter that they’re of variable energies? I have watched the Google Talk, but don’t remember seeing these sorts of specifics (or they were merely implied in physicist lingo which surpasses me).
In theory, what charged particle or EM frequency would be the most ideal for converting into electrons using photo-voltaics?
