Klystron

Abstract

Klystron is a type of microwave vacuum electron device, which converts the electron energy into microwave energy. The klystron has maximum peak power and average power comparing with other microwave vacuum electron devices. The klystron has widespread applications on accelerator, radar system, communication and TV broadcast system, RF heater, and so on. Since Varian brothers invented the first klystron, several hundred types of klystrons have been developed in recent 70 years. The art of technical state and the trend of the klystron are described briefly in this paper. In future, klystron would be developed into higher power, higher frequency, and improved continually on bandwidth, efficiency, and lifetime.
