Numerical investigation of the electrodynamic properties of a K-band multibeam monotron with a three-gap cavity

Resumo

The results of 3D numerical modeling of a low-voltage compact K-band multibeam generator of monotron type with two different modes of electron beam bunching (bunching only in the first gap or successive bunching in the first and the second gaps) are presented. These results demonstrate that it is possible to achieve a microwave radiation power exceeding 1 kW at a frequency of 18.21 GHz with an accelerating voltage of 2.45 kV and an overall efficiency of approximately 44%.
