    Spread a lot of cathodes around the outside of a vacuum chamber and
    target a deterium anode in the center.

    If the cold fusionists can use electrons, under equal peotection, so
    can you.

    Where do you want that Nobel prize sent?

    It was probably the first thing they tried.

    They have all kinds of deals where they convert eletron beams to
    radiation and vice versa for fusion.

    Electrons won't work, but it's not hard to whack duterium with
    duterium or tritium ions to get fusion... it just takes a couple
    hundred KEV or something. The net energy yield will be some insanely
    small fraction of a per cent.

    This was supposed to replace lasers compressing/heating a glass capsule
    of D2 but either the energy density isn't as high as lasers or
    something.

    You need density to get worthwhile fusion output. If you accelerate
    one duterium ion at another, or at a lump of same, that takes a lot of
    energy, and most of the time they'll just bounce off one another and
    not fuse. If the fuel is dense and very hot, a missed collision wastes
    no energy and the nuclei have many, many chances to try it again until
    they finally connect and fuse. Stars do it by gravity, and h-bombs use
    a fission bomb to briefly achieve the sort of temperature and density
    needed to get productive fusion. Just accelerating particles isn't
    enough.
