摘　　要：采用线性理论和非线性理论研究了回旋管谐振腔结构、寄生模式抑制及注波互作用等问题。设计了一支工作在95GHz的三次谐波回旋管,注波互作用结构采用标准开放式谐振单腔,工作模式为TE64,采用电压45kV、电流5A、横纵速度比为1.5的小回旋电子注。在不考虑电子注速度离散及厚度的情况下,非线性理论分析表明,该回旋管可以获得14kW功率输出,横向互作用效率约为18%,整管效率约11%。Some important issues, such as the characteristics of gyrotron resonator, suppression of spurious modes and beam-wave interaction, are studied by using linear and nonlinear theories. A 95 GHz gyrotron operating at the third cyclotron har- monic is designed. The gyrotron operates at the TE64 mode with a single standard open cavity. In this gyrotron a ideal 45 kV, 5 A electron beam with a pitch ratio of 1.5 is required. The gyrotron performance is analyzed with the nonlinear theory. It is shown that a 14 kW output power can be realized, the corresponding orbit efficiency and total efficiency are 18% and 11%, respectivelv.
