摘要

本文介绍了中国科技大学国家同步辐射实验室研发的一台食品辐照保鲜用直线加速器中电子枪的设计。通过枪体内电磁场模拟计算、优化电子枪形状、并且在考虑空间电荷效应情况下对电子束发射过程进行模拟

得到了满足设计要求的束斑尺寸。另外对电子枪的加工和调试过程也进行了介绍

通过电子枪高压老炼及出束实验表明

其各项参数性能均达到设计要求。另外对直线加速器螺线管聚焦线圈漏场对束流的影响也作了讨论

采用相应措施可增加磁屏蔽

减小漏场影响

保证束流品质。

Abstract

The design of electron gun

which is one part of a linac for food irradicidation

is described. In order to get the optimum model

the electric field in the gun is calculated

and the process of beam emission is simulated considering the space charge effects. Parameters measured in debugging experiment show that the facility has satisfied the design targets. The effect of solenoid’s leakage field on the beam of the electron gun has also been discussed.
