SARLAC: A Relativistic Electron Beam Code

Abstract

SARLAC is a particle simulation code for studying the propagation of ultrarelativistic electron beams. It is used to study the nonlinear evolution of the resistive hose instability. We have developed a fast, semi-implicit, iterative field solver which allows us to include a large number of Fourier modes in the azimuthal direction. The solver iterates about a solution of the field equations dominated by the axisymmetric (m = 0) conductivity. This technique has proved to be quite successful. We compare some results of the code with those obtained from a linearized hose simulation code, and show differences when the hose oscillations reach large amplitude. Keywords: Relativistic electron beams; Hose instability; Particle simulation code; Beam propagation code.
