为了打破传统回旋管数值模拟所采用的回旋发射产生理想电子束的局限性, 本文在理论分析94 GHz双阳极磁控注入式电子枪的结构参数的基础上, 通过共形FDTD算法对网格划分进行优化, 得到了具有横纵速度比为1.42, 最大速度零散为5.92%的高性能电子束, 并将此优化后的电子枪取代传统回旋管数值模拟时采用的回旋发射进行该94 GHz回旋 管系统的数值模拟, 并采用MPI四进程并行计算, 最终获得了具有TE03模、94 GHz、平均输出功率约在40 kW、 效率达到10.5%的高性能回旋振荡管.

In order to break the limitation of gyrotron emission producing the ideal electron beam in the traditional gyrotron numerical simulation, this paper on the basis of theoretical analysis of structural parameters for the 94 GHz double-anode magnetron injection electron gun, by optimizing the grid plot of conformal FDTD algorithm, obtains the high-performance electron beam of the horizontal and vertical velocity ratio of 1.42 and the maximum velocity spread of 5.92%, By using the optimized electron gun to replace the traditional gy rotron emission in the numerical simulation of the gyrotron system and using the four-process parallel MPI in computation, we finally obtain a TE03 mode, 94 GHz, the average output power of about 40 kW, with on efficiency of 10.5% for the high-performance gyrotron oscillating tube.-
