Energy exchange and upscattering in ion-ion collisions as they pass through the core of a Polywell/HEPS device have been analyzed. One result of these studies is a simple equation describing the energy dispersion introduced over a time t sub c by such collisions. The total energy spread introduced in an ion population by small angle collisions in the core, after repeated passes through the core by the subject ions is given. This spread both increases and decreases the energy of ions from their initially-monoenergetic level at the well center. Upscattering time can be solved for t sub c as the time required to yield an energy upscatter of 2fE or a fractional velocity upscatter of f.// particle collisions, ion-ion interactions, polywell systems.
