Isfahan University of Technology, The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 4 3 2019 11 26 Electron trajectories in free electron laser with realizable helical wiggler and ion channel guiding Electron trajectories in free electron laser with realizable helical wiggler and ion channel guiding 297 300 707 FA S. Ebrahimi M. Esmaeilzadeh Journal Article 2019 11 26   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).   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.
