Abstract
A relativistic magneto-isolated vircator on the underlimit electron beam is studied. It contained two serial magnetic mirrors and a coaxial output of microwave radiation. Its 2.5-D particle-in-cell (PIC)-simulation is carried out. Space and phase dynamics of electrons are calculated. The mode is found at which several virtual cathodes (VCs) exist simultaneously in an electron beam, i.e., the multivircator mode is realized in the device. Spectral and power characteristics of the multivircator generation with two magnetic mirrors are calculated. The dependence of the average output microwave radiation and wave resistance of the radiation coaxial output is also calculated. The spectrogram of microwave radiation is provided.
