Particle Simulation of Dusty Plasmas

Abstract

The NRL Dynamically Shielded Dust (DSD) particle simulation code hasbeen developed to model dusty plasmas. The code uses the techniquesof molecular dynamics, particle-in-cell plasma simulations, and thetest particle formulation of plasma kinetic theory. In addition,the interaction potential between dust particles is broken into longand short range parts using the P3M technique of Hockney and Eastwood.The resulting simulation code avoids the necessity of integratingon plasma time scales, but still is able to include plasma effects.
