Abstract

Abstract

Making use of the linear field theory, the dielectric Cherenkov maser with an annular plasma is analysed in detail. The beam-wave interactions corresponding to, (a) the thin annular relativistic electron beam (TAREB) surrounding the annular plasma, (b) TAREB within the annular plasma, and (c) TAREB inside the annular plasma, are discussed; and the dispersion equations are derived, respectively. Numerical solutions for the dispersion equations with a complex angular frequency are directly carried out. And the cutoff frequency, the operation frequency and the wave growth rate in the slow-wave system are obtained. Finally, the effects of related parameters on them are presented.
