摘要: 本文利用自洽非线性理论对回旋速调管放大器中的电子注-波互作用进行了时域瞬态分析,建立了多腔回旋速调管非线性理论,给出了相应的电子运动方程和复数形式的互作用瞬态场方程.探讨了调制腔、中间腔、和输出腔中注-波互作用的模型和研究方法,考虑了电子速度零散对注-波互作用的影响.最后利用FORTRAN语言给出并分析了一支Kα波段四腔回旋速调管注-波互作用的数值计算结果,经与实验值和PIC模拟结果相比较,三者较为符合.Abstract: A transient analysis in time domain of beam-wave interaction for gyroklystron is made with self-consistent field theory in this paper. A nonlinear theory for gyroklystron with multiple cavities is established, but also electron motion equations and transient electromagnetic field equations in the complex form are given. Research methods of beam-wave interaction in input cavity, idler cavity and output cavity are investigated. The infuence of speedspread is taken into account. For a Kα-band gyroklystron with four cavities, some numerical results of beam-wave interaction are given, and analyzed in Fortran Language finally. The numerical results are compared with the experimental data and the PIC results, showing that they are in good agreement.
