Precise study of the first deflecting magnet of ＂Rhodotron＂ （TT200） using transfer matrices and ANSYS11

The beam trajectory in the first deflecting magnet of ＂Rhodotron＂ TT200 has been analyzed precisely by both optical and simulation methods. We found discrepancies between these two methods at the order of （10-3） for the slit distance and deflecting radius and at the order of （10-4） for the magnetic flux density. The main goal of the paper is beam focusing, considering the angular and momentum dispersion of the particles for the magnet designed by ANSYS.

Rhodotron型加速器粒子动力学研究

Rhodotron是一种新型的CW电子加速器,已经广泛应用于辐照加工的很多领域.本文利用Parmela程序研究其动力学特性,深入分析了束团的同步条件、相聚过程以及在CW工作状态下束团相遇碰撞等一系列纵向动力学问题;并详细探讨了空间电荷效应、横向聚焦过程的实现、初始参量对横向束流特性的影响等横向动力学问题.在上述研究基础上,计算出束流损失功率的分布,并比较了模拟计算结果与Rhodotron原型机的实际参数,两者的结果基本一致,由此证明了这种研究方法的可行性.
