我们描述了网格电子枪和周期性永磁体 (ppm) 聚焦结构的设计,以创建和引导横截面为 100 毫米/spl 倍/8 毫米的 415 kV、250 A 片束。该枪旨在与 40 MW X 波段片束速调管一起使用,用于驱动加速器。使用三维 (3-D) 代码套件 AMAZE,我们设计了一种 ppm 结构,可将光束引导超过 80 厘米,传输率为 98%。
We describe the design of a gridded electron gun and periodic permanent magnet (ppm)-focusing structure to create and guide a 415-kV, 250-A sheet beam with a cross section of 100 mm /spl times/ 8 mm. The gun is intended for use with a 40-MW X- band sheet beam klystron for driving accelerators. Using the three-dimensional (3-D) code suite AMAZE, we designed a ppm structure that guided the beam over 80 cm with 98% transmission.
