Correction (followed by some semi-coherent musing ;-) > at this range of potential (< 100 keV)
...obviously that should be <100 "kV" not "keV" ...but anyway, moving on to original PF method of powering a Fusor with a simple electron gun array, here is an interesting paper which turned up - and which might have relevance to maximizing irradiation effects with coherent electrons: http://arxiv.org/ftp/quant-ph/papers/0007/0007094.pdf I am assuming that if a QM effect is (at least partly) involved in the Fusor M.O. then electron coherence (semi-coherence?) of the input would be one way to maximize that effect... is a transference possible? http://books.google.com/books?id=tkvQQElkW1wC&pg=PA161&lpg=PA161&dq=%22electron+coherence%22&source=web&ots=Qcwlwpj7JF&sig=5NrgYS82xew-qeYsXVp7On-DeS8&hl=en Jones Come to think of it (wrt "semi-coherence") and first-off- if there is such a thing which results from the interaction of a coherent input with a restrained target] then that could enhance possible hydrino or other LENR anomalies -- BTW - on a related subject: was anyone else wondering exactly how R. Roy and Kanzius achieved what they called a "polarized" RF emission, which presumably has far better coupling to a liquid ? Is it a simple grating effect? Lots of things left unsaid in that paper.... Back to Fusors - It goes without saying that I am no whiz at Hamiltonian mechanics: http://en.wikipedia.org/wiki/Hamiltonian_mechanics (and often am prone to as many hasty math errors as hasty spelling errors) ...but it stands to reason that for some purposes (i.e. powering a Fusor or a salt water H2 generator) something "less than full coherence" (i.e. semi-coherence) could still be valuable, and much easier to engineer.
