Simulation analysis and test of periodic focusing system with opening magnetic ring

  • 摘要: 当前行波管周期永磁聚焦系统的波端口位置处的磁环通常采用单向开口磁环。在波端口位置引入波导阻抗调谐支节的基础上,提出了两种不同的双向开口磁环结构。利用三维电磁仿真软件Opera-3D,分析了双开口磁环的中心轴线附近的磁场,并据此进一步介绍了带双开口磁环周期永磁聚焦系统的设计方法。为了验证带双开口磁环的周期永磁聚焦系统应用的可行性,设计和测试了一套E波段折叠波导行波管电子光学系统。在行波管试验中,电子枪发射电流83 mA,带双开口磁环的周期永磁聚焦系统聚焦的电子束流通率达到99%。
