【Abstract】 This paper introduces the development of a kind of P-band klystron with long pulse and high efficiency. By using the CSM method and introducing a second harmonic cavity, the one-dimensional design efficiency reaches 76% and the three-dimensional calculation efficiency reaches 70%. The design details of the electron gun, magnetic focusing system, beam-wave interaction system, output window and collector are described in detail, and the consideration of engineering implementation is emphasized. After baking, final assembling and other processes, the sample tube has been developed. Mass production of the P-band klystron will contribute to the development of large scale scientific facilities in China, and the autonomous and controllable goal of this kind of key core devices will be realized.更多还原
