Mathematical model of plasma-beam vircator

Abstract

The opportunity of realization of the electrovacuum device of vircator type which principle of action is based on interaction of an electronic beam with plasma is shown. Mathematical model of plasma-beam vircator was developed on the basis of which basic target characteristics and power of the device are calculated. Graphic dependences of power plasma-beam vircator on concentration of particles of plasma and on the frequency of generation at different pressure of working gas have been obtained. Theoretical and experimental research have shown, that with increase of pressure of working gas, the increase of power up to 90 GW and essential expansion of operation band of frequencies of the device occur.
