根据工程实际的需要,对目前使用的微波管电子光学计算程序进行一些改进。一方面重新设计了友好的人机交互界面,另一方面从改进电子枪阴极电子发射模型,考虑温度、相对论效应和电子初始能量等因素的影响,以及计算电子轨迹时采用变步长Runge-Kutta法等来修改原程序算法。通过计算结果的对比,表明改进程序更加接近实验结果,收敛性更好。
According to the actual needs of the project, some improvements have been made to the currently used microwave electronic tube optical computing program. On the one hand, the friendly man-machine interface was redesigned. On the other hand, the influence of temperature, relativistic effect and initial energy of electrons on the electron gun cathode electron emission model was improved, and the Runge-Kutta method To modify the original algorithm. The comparison between the calculated results shows that the improved program is closer to the experimental results and has better convergence.
