Research of Resonance Regimes of Axisymmetrical Oversized Open-System Relativistic Diffraction Generator

The results of modeling the interaction of a tubular electron beam and a field in an oversized axisymmetric relativistic diffraction generator on a periodic sequence of tori are presented. A numerical analysis of the generator response to the effect of an electron beam modulated at a given frequency in resonant modes is carried out. The diffraction boundary value problem was solved by the method of integral equations. The influence of the structure parameters by resonant frequencies upon the distributions of the components of the electromagnetic field in the space of interaction between the flow and the field were studied.
