| 摘 要： | 应用自行编制的电子注-波互作用的自洽非线性模拟程序,我们对Ka波段二次谐波回旋速调管放大器的注-波互作用进行了研究.通过对回旋速调管放大器的数值模拟,我们详细描述了二次谐波电子注-波互作用过程中电子群聚的物理图景;并研究了不同变化参数(漂移管长度和静磁场强度)对电子效率的影响.模拟结果表明:设计的二次谐波回旋速调管放大器的电子效率为15.4%,相应的输出功率约为161kW.

| Abstract: | The beam-wave interaction of a designed Ka-band second harmonic gyroklystron amplifier is studied by using a self-consistent nonlinear simulation program.With the numerical simulation of the gyroklystron amplifier,the physical picture of the electron bunching in the second harmonic beam-wave interaction was presented and the effect of the different parameters(such as drift tube length and static magnetic field) on the electron efficiency was studied.The simulation result shows that the electron efficiency of the designed gyroklystron amplifier equals to 15.4% and the corresponding output power is about 161kW. |
