均匀场聚焦带状注速调管电子光学系统的研究

Study on Sheet Beam Klystron Electron Optics System in Uniform Magnetic Field

本文系统地阐述了均匀场聚焦带状电子注的传输理论,设计了柱面阴极皮尔斯电子枪,模拟显示轨迹的层流性较好;设计了产生均匀磁场的磁聚焦结构,在1 m长的距离内,成功地实现了X波段100 MW带状电子注的稳定传输,电子注通过率达到100%;同时设计了收集极新型结构,给出了电子注在收集极内的发散情况。

A novel type of sheet-beam-klystron, electron-optics-system in uniform magnetic fried, has been successfully developed. The hardware,including a cylindrical electron gua,a uniform magnetic field focusing system for the X-band 100 MW sheet beam klystron,and a new type of collector, was designed and constructed. Our simulated results show that the electron trajectories have no intersections. Moreover, the electron transmission was evaluated to be 100% within 1 meter.The diffusion of the electron beam in the collector was also discussed.
