KMRAD: A Linearized Particle Code for the Study of Resistive Instabilities.

Abstract

A linearized electromagnetic particle simulation code KMRAD has been developed to look at resistive instabilities on electron beams. The code can simulate three-dimensional dynamics, but by use of Fourier transforms in two directions, only one spatial direction needs to be resolved. For cold beam equilibria, KMRAD predicts growth rates which closely agree with those obtained from an exact cold-fluid code. For a Bennett equilibrium, comparisons between KMRAD and available analytic models are presented, and several discrepancies are noted. (Author)
