Low-voltage planar cyclotron resonance maser based on a confocal cavity

The results of simulation of both electron-optical system and the cavity of the low-voltage planar cyclotron resonance maser (CRM) have been presented. The electron-optical system (EOS), which forms a sheet helical electron beam (HEB) with the value of the pitch factor ≥ 1 was obtained. Electron beam energy characteristics were obtained as the result of trajectory analysis for EOS. Also the CRM cavity mode structure and its dispersion characteristics were simulated and analyzed.
