摘要 通过对94GHz基波复合腔回旋管中谐振腔结构、电子注参数以及注-波互作用过程的模拟计算研究,分析了复合腔回旋管的高频结构特性和工作参数优化问题。给出了基波H61-H62模式对复合腔回旋管的模拟设计结果。数值模拟结果表明:在电子注电压40kV、电流5A、电子横纵速度比1.3、工作磁场3.6T时,回旋管可获得78kW的输出功率和39%的互作用效率。 The paper studies the structure,electron beam parameters and beam-wave interaction of a complex cavity with gradual transition employed in the 94 GHz gyrotron.A self-consistent field nonlinear theoretical analysis is used and numerical simulation results for electron beam interaction with the moded air H61-H62 are given.A pulse output power of 78 kW is obtained for the gyrotron by simulation at the beam voltage of 40 kV with beam current of 10 A,velocity ratio of 1.3,and magnetic field of 3.6 T,corresponding to a beam-wave interaction efficiency of 39%.
