10 MeV电子辐照加速器的穿透深度大、加工领域广,在电子辐照领域具有广阔的发展前景,其中,10 MeV行波电子直线加速管是关键核心部件,其性能指标和工作稳定性直接决定了整台加速器的运行状况。通过对国内外相关加速结构研究发展的调研可知,对于10 MeV电子辐照用加速管,等阻抗行波加速结构便于设计加工和调配,更适合广泛应用。本工作主要围绕10 MeV等阻抗行波加速结构的物理设计,展开束流动力学计算和射频结构尺寸的确定,并形成了较为系统的
The 10 MeV electron irradiation accelerator has a large penetration depth and a wide range of processing fields and has broad prospects for development in the field of electron irradiation. Among them, the 10 MeV traveling-wave electron linear accelerator tube is a key core component and its performance index and working stability are directly Decide the operation of the entire accelerator. Through the research on the research and development of accelerating structures at home and abroad, we can see that for accelerating tubes with 10 MeV electron irradiation, the impedances of traveling wave accelerating structure is easy to design, process and deploy, which is more suitable for a wide range of applications. This work mainly focuses on the physical design of 10 MeV impedances such as the impedance traveling wave acceleration structure, launching beam dynamics calculation and determining the size of radio frequency structure, and has formed a systematic
