Abstract :
A new configuration of virtual cathode oscillator is studied for high-power microwave generation. It is similar to previous reflex triode but has an improved structure allowing better coupling between the electron beam and the electromagnetic field. It is tested on repetitive pulsed power generator ≪ETIGO-IV≫. Microwave output power and frequency were diagnosed experimentally and the results were compared with numerical simulation results obtained by using ≪MAGIC≫ simulation code.
