Theoretical and experimental researches on the X-band five-unit transit-time tube oscillator

This paper is mainly concerned about the theoretical and experimental research of a novel high-power microwave device of the X-band five-unit Transit-time Tube Oscillator (TTTO), which is based on the transit-time effect. Firstly, the structure model of this kind of oscillator is put forward, and the high-frequency characteristics of the resonator (or cavities) are investigated, which is TM01-3π/5 mode. Secondly, resorting to the one-dimension analysis, the interactions between the electrons and the field of different modes in the resonator are researched. It shows that this TTTO can generate high power microwave. Thirdly, this TTTO is simulated, optimized and designed by the particle simulation code. Finally, the experimental research is carried out. After a series of adjustment, employi
