摘　　要：运用全电磁2.5维粒子模拟程序MAGIC,对螺旋线行波管中注-波互作用的非线性过程进行了模拟分析,得到了管子的功率、增益和效率等电性能参量,模拟结果与实测数据吻合良好。对整管长度、电子注电流、电压和聚焦磁场等量进行了优化,获得了管子最佳化运行的工作参数。A two and one half dimensional electromagnetic particle-in-cell simulation code has been used to study the nonlinear haamwave interaction of a helical traveling-wave tube. The simulation results agree with the measurements very well, including output power, gain and efflciency.The tube length,electron beam current, voltage and focus magnetic field have been optimized, and the optimum working conditions have been obtained.
