摘　　要：扫描磁铁的优良性能是加速器高效辐照的关键,本文采用Poisson Superfish软件仿真二极电磁铁的磁场分布情况,为带电粒子加速器的扫描装置设计了一种方形二极电磁铁,通过改变二极电磁铁的形状来调整磁场分布,对中平面磁感应强度的分布曲线进行比较分析,得到了能够增加粒子束扫描均匀度、提升辐照质量的扫描磁铁的最佳形状,为加速器高效辐照提供了关键技术支持。The excellent properties of the scan magnet are the In this paper, the magnetic field distribution of diode magnet software, a square diode magnet is designed for scanner in key for high efficient irradiation with accelerator. is simulated and analyzed with Poisson Superfish charged particle accelerator. Appropriate adjust the magnetic field distribution by changing the shape of the diode magnet, and compare the distribution curve of their midplane magnetic induction intensity, the scanning magnet＇s optimal shape is obtained that can increase the scanning particle beam uniformity and improve the quality of irradiation. This work is very important for effective irradiation by accelerator.
