| 摘 要： | 采用了回旋管多模自洽非线性注-波互作用理论,在多个模式同时存在下,每个模式的纵向场随时间和空间变化,最终达到平衡状态。编制了多模自洽非线性计算程序,对220 GHz回旋管进行了数值计算,分析了回旋管中的模式竞争问题,验证了设计的合理性。

| Abstract: | A non-linear self-consistent multimode theory is built for a 220 GHz gyrotron.In this theo- ry,there are several modes exist synchronously.The longitudinal field profile of each mode is space-time dependent,and come to equilibrium at last.The theory has been developed along with a computer code to carry out the numerical calculation.The code has been used to analyze the mode competition of a 220 GHz gyrotron oscillators.The result has validated the rationality of our design. |
