以辐照加速器为辐照源的辐射加工在发达国家已成为经济发展的新增长点。通用辐照加速器的电子输出能量要么不能改变，要么变化范围很小且不能连续调节。我们研究出一种新型的驻波辐照加速器结构，其输出能量在1.2MeV-12MeV范围内连续可调。该结构代表目前辐照加速器研究的最前沿课题，它能否正常运行的关键是束流动力学与输入功率匹配、以及束流损失问题。在本项目中，基于目前的数字矢量IQ控制技术，我们将研究与该加速器匹配的束流动力学模型、工作机理以及相应的数字低电平控制系统，包括幅度反馈控制算法和相位反馈控制算法；大功率高频功分器的精确调节与控制问题。. 通过本课题研究，我们将解决该加速器技术实现途径,力争取得若干有显示度的研究成果，形成一系列自主知识产权，为实现输出能量连续可调辐照加速器的稳定工作提供必要的的基础研究支撑。

Irradiation processing with accelerator has been their new economic growth point in developed country. At present, the most irradiation accelerators cannot vary its output energy, even can, but their output-energy variation range is too narrow. In order to solve those issues, we has developed a new standing wave accelerating structure, which is used for a variable output-energy irradiation accelerator (1.2MeV-12MeV). The new accelerating structure represent the most advanced contents in the irradiator research. The match between the beam dynamic and the input power and the beam loss are the key questions in the accelerator normal operation. In this subject, based on the vector IQ control technology, in order to make the new accelerating structure work well, we should study the beam dynamic model matched the accelerator, working mechanism, the according high frequency low level vector control method (the magnitude feedback control algorithm and the phase position feedback control algorithm), and the close regulation and control on the high power divider. . With the project being completed, we will have an outstanding research in the irradiation accelerator with the variable-energy output, and we will take the first step in settling the difficult problem of the accelerator's energy continuously adjusting.
