Abstract

This paper describes an analytical approach to consideration of the tradeoff between the gain and the bandwidth in gyroklystrons and gyrotwystrons with stagger-tuned cavities. This approach is based on the “point-gap” model, in which short cavities are responsible for electron energy modulation only, while orbital phase bunching caused by this modulation proceeds in long drift sections. The paper contains a review of results of the analysis of stagger-tuned gyroklystrons and gyrotwystrons obtained previously. It also includes new results of the study of gyroklystrons in which different cavities operate at different cyclotron harmonics
