BGK-type waves in slowly evolving plasmas

POSTER

Abstract

We introduce a specific class of BGK-type waves that arise naturally in slowly-evolving Vlasov plasmas, characterized by a distribution function in terms of the canonical particle action. Using some naturally motivated assumptions and the constraints of self-consistency, we determine the wave's nonlinear properties and compare these to driven Vlasov systems. We then show how this may lead to reduced models of driven plasmas relevant, for example, to simulated Raman scatter.
