摘要
采用横向螺旋摇摆磁场,通过非线性模拟程序计算同轴回旋自谐振脉塞放大器的输出功率和束波耦合效率,结果显示采用横向螺旋摇摆磁场能将饱和电子效率从恒定导引磁场情况下的7%提高到13.5%左右,使饱和输出功率相比纵向恒定导引磁场下的输出功率提高将近220kW。
A new method to enhance the efficiency for a coaxial-waveguide Doppler-shifted cyclotron autoresonance maser （CARM） using transverse helical wiggle magnetic field, which is help to suppress stimulated absorption, is proposed. Nonlinear simulation result indicates that that the beam-wave interaction efficiency could be increased significantly from 7% to 13.5% when the transverse helical magnetic field is employed.
