High Energy Ion Expansion in Laser-Plasma Interactions.

Abstract

Measurements of energetic ion distributions produced from CD2 and CH2 targets are compared with a numerical model. The model describes the ambipolar expansion of hot electrons and two relatively cold ion species from a pressure gradient. For CD2 the plasma expansion is adequately represented by a single ion species, whereas for CH2 two ion fluids are required to account for the energy and the relative behavior of the high energy ion species.
