速调管周期反转永磁聚焦系统的三维模拟研究

3D Simulation Study of Reversible Periodic Magnetic Focusing System in Klystron

在速调管的设计和应用中,选择一套良好的聚焦系统对整管的性能有着重要意义。本文对大功率速调管中的周期反转永磁聚焦系统中各部件的尺寸进行了优化设置,得到了相对较平稳、反转区小的磁场分布。同时对软件的计算应用作了介绍。

In the design and application of klystron,how to select a suitable focus system with acceptable performance can make grate significance to it.This paper has simulated Reversible Periodic Magnetic Focusing System and optimized the adaptive size of each parts.A flat magnet field distribution with short reversible area has been achieved.The simulation process was particularly introduced in this paper.
