介绍了利用加速管的场分布计算单腔微波参量的一种方法.在已知耦合腔链各本征模式的谐振频率和电场分布的条件下,可以通过回路方程组求出耦合腔链的单腔频率和腔间耦合系数.这种方法给加速管设计和调谐带来了很大帮助,在加速腔数目较多或者结构非均匀的条件下尤为有效.
A method to calculate the single-cavity microwave parameters by using the field distribution of the accelerating tube is introduced.Under the known resonant frequency and electric field distribution of each eigenmode of the coupled cavity chain, the single Cavity frequency, and intercavity coupling coefficient.This method is very helpful for the design and tuning of accelerating tube, which is especially effective when the number of accelerating cavities is large or the structure is not uniform.
