目前处于设计阶段的哈尔滨工业大学空间辐照效应装置,其核心部件是由1台10 MeV的注入器、1台300MeV的同步加速器以及输运线构成的加速器装置。同步加速器中引出的质子束流被用于辐照研究。基于装置的概念设计,优化了其同步加速器部分的设计。设计了新的磁聚焦结构,优化了基于新的磁聚焦结构的多圈注入系统的凸轨变化模式,提高了注入效率。为了更好地优化引出束流的时间结构,慢引出系统采用了RF knock-out的方法。为了满足精准辐照的要求,研究了RF Kicker的频率调制,发现RF Kicker的双频调制能使得引出束流更均匀。 Currently in the design stage of Harbin Institute of Technology space radiation effects device, the core component is a 10 MeV injector, a 300MeV synchrotron and transport line consisting of accelerator device. The proton beam from the synchrotron is used for irradiation studies. Based on the conceptual design of the device, the design of its synchrotron part is optimized. A new magnetic focusing structure is designed and the pattern of the convex change of the multi-turn injection system based on the new magnetic focusing structure is optimized to improve the injection efficiency. In order to better optimize the time structure of the extracted beam, the slow-out system uses the RF knock-out method. In order to meet the requirement of precise irradiation, the frequency modulation of RF Kicker was studied and it was found that RF Kicker’s dual-frequency modulation can make the outgoing beam more uniform.
