Modification of plasma solitons by resonant particles
Abstract
A consistent theory of plasma soliton interaction with resonant particles is developed. A simple derivation of a perturbed Kortewegde Vries equation with the interaction term is presented. It is shown how the known limit cases (such as OttSudan's, etc.) can be derived from the general equations and what their regions of applicability are. Some effects caused by the solitonparticle interaction (amplitude changerate, tail formation, etc.) are analyzed by means of a recently developed perturbation method. The analytical results are compared with a direct numerical integration of the perturbed Kortewegde Vries equation. Laboratory measurements carried out in a strongly magnetized, plasmafilled waveguide and results from particle simulation are interpreted in terms of the analytical results.
