摘要
针对W波段4路平面集成行波管收集极的应用需求,通过计算机仿真技术(CST)软件对4路阵列电子注共用的平面收集极进行优化设计,并结合注-波互作用后的电子注能量分布特性分析,计算了在不同电压下收集极的效率和返流情况,最终选定-11.4 kV为收集极工作电压,并分析了工作电压0 kV和-11.4 kV时的电子轨迹分布。计算了收集极的热损耗功率,利用ANSYS软件分析了收集极工作于-11.4 kV时的热分布情况。研究结果表明,该收集极能够高效率地回收4路互作用完成后电子注能量,收集极工作电压为-11.4 kV时效率最高且没有返流,此时热损耗功率产生的温度变化在可承受范围之内。
To meet the application requirements of four beams W-band planar-integrated traveling wave tube collector,a four-electron-beam array shared planar collector is designed by Computer Simulation Technology(CST)software.Firstly,the spent-electron-beam characteristics are analyzed.Then,the efficiency and back streaming current of the collector at different voltages are obtained,and the operating voltage of the collector is determined to be-11.4 kV.The electron trajectories at 0 kV and-11.4 kV operating voltages of the collector are simulated and analyzed.Finally,the thermal loss power of the collector is calculated,and the temperature distribution is simulated by ANSYS software.The results show that the collector can efficiently recover the energy of spent-electron-beam after beam-wave interaction.When the operating voltages of the collector is-11.4 kV,the efficiency is the highest and there is no back streaming current,and the heat dissipation temperature is within the tolerable range.
