Quenching of the Beam-Plasma Instability by Mode Mixing at a Density Discontinuity,

Abstract

Experiments on the spatial instability of a beam-plasma system led to the observation that the instability is quenched when irradiated by high power microwaves. It is conjectured that this effect is due to a local decrease in plasma density in the irradiated region. A theoretical model is detailed that explains the salient features of the observed effect. Auxiliary measurements on a system with a controlled density gradient are presented that give strong support for the proposed mechanism. (Author)
