Abstract
Coupled Boltzmann equations for particles with two charge states have been solved to describe the angular evolution of a beam which is charge exchanging through collisions with a background vapor. The solutions are applied to the processes D0+Cs→D−+Cs+ and D−+Cs→D0+Cs + e using measured differential cross sections where available. By accelerating and stripping a D− beam, an intense high-energy beam can be formed for thermonuclear fusion experiments and reactors. It is concluded that angular scattering does not place a significant limit on the beam quality, although the cesium line density must be the minimum to reach a charge-state equilibrium in the beam.
