强流质子加速器残余气体电离型束流剖面探测器研究

The development of high-intensity proton accelerator become more and more important. Such as in high energy physics, spallation neutron source, accelerator driven subcritical system and radiation-hard material study etc, these applications require the high-intensity proton accelerator as the platform. The traditional interceptive way cannot fit the request of the beam commissioning and operation as the beam current and energy increasing. This project is aimed to carry out a systematic study on the ionization profile monitor to improve its application on high intensity proton accelerator. Many intensive study works will be carried out, including uniform electric field design, special magnet design, suppression of the secondary emission electrons, and so on. A prototype based on the Channeltron scheme will be manufactured and tested at CSNS for IPM principle study. The successful implement of this project will improve the composition of the domestic beam instrumentation system of the high intensity proton machine significantly, and have significant scientific values and practical importance. The applicant and the team has already laid a good base on the subject in the past years, and is capable to execute the research program with high quality.

强流质子加速器的发展日益重要，如在高能物理研究、散裂中子源、加速器驱动的次临界核能系统和抗辐射材料研究等方面，这些都需要强流质子加速器作为平台。随着束流流强和能量的提高，传统截束型测量方法已不能满足加速器调试运行的需要。本课题将针对残余气体电离法束流剖面探测器开展研究工作，对其在强流质子加速器上的应用进行系统性集成研究，并深入开展电场均匀化、特殊磁铁设计等研究工作。以此为基础进行基于单通道电子倍增器的IPM原理性试验装置的设计并以中国散裂中子源加速器为实验平台进行带束流实验。本课题的成功开展，可有力完善国内强流质子加速器束测系统的组成，具有显著的学术价值和实际意义。申请人及团队在该研究方向上已具有很好的基础，有能力开展并高质量地完成相关的研究工作。
