Electrostatically confined fusion reactor

    does an electrostatically confined plasma fed tritium produce energetic e3nough neutrons to create tritium if allowed to irradiate deutrium ?

    It is more effective to produce tritium from an (n,alpha) reaction with Li.

    The problem of producing T from D is that D has such a low cross-section for thremal neutron absorption. The microscopic absorption for thermal n's by D is approximately 0.5 mb (or 0.0005 barn) vs the n-absorption cross-section for H of ~0.33 barn, and ~0.9 barn for Li-6.

    Also D-D fusion produces T in ~50% of reactions, but again the energy input is considerable, and much greater than n-absorption by Li-6.
