A theory of self-electric and self-magnetic fields of a relativistic electron beam passing
through a one-dimensional planar wiggler and an ion-channel is presented. The equilibrium …

Significant progress has been made using plasma channels to guide relativistic e-beams in
magnetostatic wiggler free-electron lasers (FELs). In this regard, we study the interaction of …

The free-electron laser FEL in the millimeter or submillimeter regime operates with a high
density and low energy relativistic electron beam. In this operating regime, the self-electric …

The effects of self-fields on the free electron lasers (FELs) with a helical wiggler and ion-
channel guiding are considered. The steady-state orbits for a single electron in this …
