摘　　要：介绍一种对行波管中使用的微型多级降压收集极进行电、热及动力学优化设计的系统方法,同时期望这样一种方法能够移植到行波管其他部分的设计优化中。优化所得的收集极在全频带上的仿真效率达到79.5%以上,其散热能力满足环境要求,热裕量充分,并且结构强度远超环境需要。In this paper we introduce a systematic method about electronic, thermal and kinetic optimization of a Micro Multi-stage-Depressed Collector （MDC） used in Traveling-Wave-Tubes （TWTs） ; at the same time, we expect that this technique can be transplanted to the optimization of the other section of TWTs. After optimization, the MDC＇s efficiency is above 79 percent all over its band-width; its heat dissipation ability fulfills the request of environment, and has enough thermal margins. Finally, the intensity of its structure exceeds the request of environment a lot.
