Abstract

The influence of the longitudinal space-charge waves of a coherently gyrophased, helical relativistic electron beam on the cyclotron maser instability is investigated in a cylindrical waveguide configuration using a three-dimensional kinetic theory. A dispersion relation that includes waveguide effects is used to examine detailed stability properties of the cyclotron maser interaction. It is shown that, in general, the effects of space-charge waves on a coherently gyrophased beam are suppressed in a waveguide geometry in comparison with an ideal one-dimensional cyclotron maser with similar beam parameters.
