Abstract

It is shown that the inclusion of the equilibrium self fields of the electron beam results in chaotic electron motion in the field configuration consisting of a constant-amplitude helical wiggler magnetic field and a uniform axial guide field. The threshold value of the self-field parameter {epsilon} = {omega}{sub pb}{sup 2}/4{Omega}{sub c}{sup 2} is determined for the onset of chaoticity in the Group-I and Group-II orbits for the parameter regime corresponding to moderately high beam current (and density). The time scale for self-field-induced changes in the particle orbits is found to be of the order of beam-transit time through one wiggler period. 15 refs., 5 figs.
