Processes of virtual cathodes interaction in multibeam system

Abstract

Two variants of schemes of a multibeam vircator are proposed and studied in this paper. Numerical analysis of the influence of various parameters of these systems (magnitude of the external magnetic field and detuning of beam currents) on the generation characteristics was conducted. The possibility of synchronizing several virtual cathodes in a single drift space of a multibeam vircator is demonstrated. The regime maps of basic control parameters of the system are built. The possibility of effective interaction of several virtual cathodes in a single drift space is analyzed, and the conditions for implementing an effective addition of powers of each beam at the output load are determined.
