Study of Influence of Magnetic Field on the Processes of Virtual Cathode Formation and the Non-Stationary Dynamics of Particles of Electron Beam in Low-Voltage Vircator

The results of the study of nonlinear non-stationary processes in the non-relativistic electron beam in the breaking field (the scheme of the low-voltage vircator) in the regime of the virtual cathode (VC) presence are given. The analysis has been carried out in the framework of 2D numerical model. The results of the modeling of the system with and without focusing the electrons by the external magnetic field are compared.
