Experiments on highly efficient operation of the auto-resonant peniotron oscillator

Abstract

Abstract The auto-resonant peniotron has been theoretically expected to have a very high conversion efficiency (nearly 100%) for an ideal electron beam with an appropriate value for the velocity ratio interacting in a suitable circuit with an electromagnetic wave whose phase velocity is equal to the velocity of light in free space. This paper presents experimental results showing more than 70% electronic efficiency obtained from an auto-resonant peniotron oscillator with a magnetron type cavity.
