辐照用紧凑连续波电子加速器的物理设计

为适应工业电子加速器需求增多的现状,提出了一种新型的结构紧凑的连续波电子加速器,运行频率为180MHz。依靠置于加速腔外的多个偏转磁铁,使电子束多次穿越加速腔,从而得到持续的加速。设计过程中,用CST软件对谐振加速腔进行了优化,用Parmela软件模拟了束流的粒子动力学。粒子纵向稳定度和横向聚焦也通过模拟进行了分析和验证。结果显示:此种新型加速器能得到9MeV,100kW的稳定电子束流。

Physical design of compact continuous wave electron accelerator for irradiation

To meet the increasing demand for domestic industrial electron accelerators, a new type of compact continuous wave (CW) electron accelerator which works at 180 MHz is proposed. It accelerates the electron beam within the cavity and performs successive acceleration by several bending magnets located outside the cavity. The resonant cavity design is optimized by CST and the particle dynamics is simulated by Parmela. The longitudinal stability and the transverse focusing of electron beams are also analyzed and verified by beam simulation. The result shows that this accelerator can accelerate continuous beams at the output power of 100 kW with a beam energy of 9 MeV．
