摘要
无箔二极管中电子束的扩张和传输完全依赖于外加导引磁场控制。在考虑阴极杆发射的情况下,用PIC方法模拟了无箔二极管中电子束形成过程,据此对导引磁场和阴阳极结构的优化设计提出一些建议。
The foil-less diode is one of the best structures for producing an intensive electron beam with long pulse and repetitive operation frequency. However the propagation of the electron beam should be fully controlled by guiding magnetic field. Under the consideration of the electron emission from the cathode, we use PIC method to simulate the process of the electron beam formation in the foil-less diode. Then some suggestions are given for the optimum design of the foil-less diode by choosing proper guiding magnetic field and diode structure.
