Abstract : Numerical techniques exist for modeling particle beam dynamics in high current accelerators at several levels of fidelity. Equilibria can be determined with beam envelope codes, particle ray-tracing, Vlasov equilibrium solvers, and single-disk particle codes. The linear stability of these equilibria is addressed with dispersion relations solved numerically, linearized PIC codes, and single- and multi-component beam centroid programs. Beam nonlinear dynamics are investigated with multidimensional PIC codes employing either the complete electromagnetic field equations or various approximations to them. Each of these options is discussed, and several examples are provided.
