Electron trajectories in free electron laser with realizable helical wiggler and ion channel guiding

Abstract

A detailed analysis of electron trajectories in a realizable helical wiggler free electron laser with ion channel guiding using electron (single particle dynamics) is presented. Conditions for stability of electron orbit have been investigated, calculations are made to illustrate. Conclusion shows that there are differences stable (unstable) condition(s) electron trajectories between ideal helical wiggler(2D) and realizable helical wiggler (3D).
