Abstract

Fast calculation of3D non-linear space-charge fields is essential for the simulation ofhigh-brightness charged particle beams. We report on our development of a new 3D spacecharge routine in the General Particle Tracer (GPT) code. The model is based on a nonequidistant multigrid Poisson solver that is used to solve the electrostatic fields in the rest frame ofthe bunch. Since the multigrid Poisson solver depends only linearlyon the number of mesh points for the discretized electrostatic problem the space-charge routine scales linearly with the number of particles in terms of CPU time. This performance allows over a million particles to be tracked on a normal Pc. The choice of the routine parameters for an optimal performance will be discussed with the model of a spherical bunch.
