20-Mw pulsed amplifying klystron operating in positive feedback mode

The results of investigation of the regenerative oscillation amplification mode and the selfoscillation synchronization mode for the power pulsed amplifying positive-feedback klystron are reported. In Ref. there was described the autogenerator on the KUY-12 pulsed amplifying klystron, used for feeding the accelerating sections of the electron linac. To enhance the self-oscillation frequency stability, a high-quality resonator is introduced into the feedback circuit. This however results in noticeable increase in the oscillation growth time with respect to anode pulse. The investigation results of the KUY-12 operating either in the oscillation regeneration mode or in the self-oscillation frequency synchronization mode are presented
