摘要
二次谐波回旋管所需磁场仅为基模的一半,极大地降低了对工作磁场的要求。基于回旋管线性和自洽非线性理论设计了一只0.5THz回旋管,采用TE56模为工作模式,分析了多项关键参数对注波互作用效率的影响,当其工作电压为49kV,工作电流为5 A,工作磁场为时9.94T,效率为22.52%,输出功率可达55kW。
The operating magnetic flux density second harmonic gyrotron required is only half of the fudamental mode. According to the gyrotronlinear theory and the nonlinear self-consistent thory, the design of a a second harmonic 0.5 THz gyrotron operating in is presented. The impacts of several key parameters on the efficiency of beam-wave interaction is analyzed. The results shows that when the gyrotren operates at 49 kV beam voltage, 5 A beam current and 9.64 magnetic flux density, it＇s efficiency of beam-wave interaction is 22.52% and it＇s output power can reach 55 kW.
