摘　　要：介绍了一款长脉冲、高效率的P波段速调管的研制情况,其运用CSM群聚方法通过二次谐波腔使一维设计效率达76%,三维计算效率为70%。详细叙述了电子枪、磁聚焦系统、注波互作用系统、输能装置、收集极的设计细节,着重强调了其在工程化实现方面的考虑。经过排气、总装等工序已经完成了样管研制。该P波段速调管的量产将有助于我国大科学装置的发展,实现功率源关键核心器件的自主可控。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.
