摘要
从降低收集极表面峰值功率和平均功率入手,设计了一种由12个横向椭圆交流线圈和2个轴向直流线圈组成的磁场扫描系统。针对140 GHz、TE28,8模、1 MW功率输出回旋振荡管收集极的设计参数,结合电磁场理论和带电粒子电磁软件仿真,获得收集极表面上电子注的峰值和平均功率密度分别不超过404.91 W/cm^(2)和244.01 W/cm^(2),以及扫描长度达到443.33 mm的扫描效果,有效地缓解了收集极功率耗散和冷却的压力。
Starting from reducing the peak power and average power on the collector surface of a gyrotron oscillator,we have designed a magnetic field scanning system composed of 12 transverse elliptical AC coils and 2 longitudinal DC coils.According to the design parameters of the collector electrode of 140 GHz,TE28,8 mode,1 MW gyrotron oscillator,and combining electromagnetic field theory with particle-in-cell(PIC)simulation program,the scanning system can realize that the peak and average power density of the electron beam on the collector surface are not more than 404.91 W/cm^(2) and 244.01 W/cm^(2) respectively with a scanning length of 443.33 mm,which effectively alleviates the pressure of power dissipation and cooling of the collector.
