| 摘 要： | 近年来,对紧凑、稳定及可靠型电子直线加速器的需求越来越多,其能量主要分布在几百keV到十几个MeV的范围内,其中需求最多的则是能量在MeV量级的微波电子直线加速器。在这种形势下,中国科学院高能物理研究所正在研制一台S波段6 MeV的边耦合电子直线加速器,本文对基于该加速器的模拟计算研究进行了介绍。EGUN和HFSS分别用来设计电子枪和边耦合加速结构。通过将EGUN计算得到的电子束流参数和HFSS计算得到的三维电磁场分布数据引入到PARMELA中,完成了对该加速器的多粒子动力学研究。模拟结果显示,所设计的加速器完全能够满足设计指标的要求。最终,在考虑束流负载效应的因素后,完成了边耦合加速结构的微波结构设计。

| Abstract: | Nowadays, the demands for compact, stable and reliable electron accelerators with energies ranging from several hundred keV to a few MeV are growing tremendously, especially the RF electron linacs in the MeV energy range. In this situation, Institute of High Energy Physics(IHEP) is developing an S-band 6 MeV side coupled electron linac. This paper presents the start-to-end simulation studies on this linac. The electron gun and the side coupled accelerating structure were modeled by EGUN and HFSS, respectively. By introducing the electron beam parameters calculated by EGUN and the 3D RF electromagnetic data of HFSS simulation into PARMELA, multi-particle beam dynamics studies for the linac were carried out. The simulation results show that the beam quality at the linac exit is acceptable. A 3D RF design of the side coupled accelerating structure was also investigated by taking the beam loading effect into consideration. |
