Influence of finite radial geometry on the growth rate of ion-channel free electron laser
M Bahmani, A Hasanbeigi, H Hamzehpour - Physics of Plasmas, 2013 - pubs.aip.org
The influence of finite radial geometry on the instability of a tenuous relativistic electron
beam propagating in an ion-channel in a waveguide is investigated. The instability analysis
is based on the linearized Vlasov-Maxwell equations for the perturbation about a self-
consistent beam equilibrium. With the help of characteristic method the dispersion relation
for the TE-mode is derived and analyzed through the numerical solutions. It is found that the
positioning of the beam radius R b relative to the waveguide radius R c, and the ion …
