摘要
介绍一台用于热阴极微波电子枪的双重入驻波腔及其阴极结构．根据微波枪束品质要求，首先定出腔体基本参数，然后报告了腔形、场分布、谐振频率、耦合度等的设计考虑，并给出腔体测量结果，最后介绍了阴极结构的设计．
This paper introduces a single cell re-entrant cavity and its cathode structure used in the thermionic microwave gun. The essential parameters of the cavity are chosen according to the requirements of produced electron beam. We report design consideration on cavity shape, field distribution, resonant. frequency and coupling coefficient. Then we give the cold RF measurement results. The cavity is successfully used in the gun. Results of simulations is presented and is compared with measurements.
