摘　　要：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。给出并分析了一支工作在TE01模Ka波段四腔回旋速调管注-波互作用的数值计算结果,当电子注电压为72.8kV,电流为11.8A,速度零散为5%时,可以得到335kW的最大饱和功率输出,39.6%的电子效率及320MHz的饱和带宽,与实验值相比较,二者较为吻合。A transient analysis in time domain of beam-wave interaction for gyroklystron is made with self-consistent field theory.A nonlinear theory for gyroklystron with multiple cavities is then established,and corresponding electron motion equations and transient electromagnetic field equations with a complex form are given.For a Ka-band gyroklystron with four cavities,some numerical results of beam-wave interaction are given and analyzed.A saturated output power of 335 kW,corresponding to efficiency of 39.6% and saturated bandwidth of 320 MHz is achieved with a 72.8 kV,11.8 A electron beam in TE01 mode when the speed spread is 5%.The numerical results agree well with the experimental data.
