近年来,质子束功率约为50kW(70MeV,引出流强0.75mA)的回旋加速器在放射性核束(RIB)生产以及核医学应用等方面具有广泛的应用前景,美国、意大利等多个国家实验室十分关注并提出项目建议[1-2]。中国原子能科学研究院在强流负氢回旋加速器的理论研究与设计技术上已有了长期的经验积累[3-4],近期完成了1台用于放射性核束产生及医用等多用途的70MeV强流回旋加速器CYCIAE-70的物理设计。CYCIAE-70主体结构采用了四直边扇的紧凑型结构,可加速H-和D-离
In recent years, a cyclotron with a proton beam power of about 50kW (70MeV, a draw-out current of 0.75mA) has a wide range of applications in the fields of radioactive nuclear beam (RIB) production and nuclear medicine applications. National laboratories such as the United States and Italy Pay close attention to and propose the project [1-2]. China Institute of Atomic Energy has long accumulated experience in the theoretical research and design of high-current negative cyclotron [3-4] and recently completed a multi-purpose 70MeV Physical Design of a Strong Cyclotron CYCIAE-70. CYCIAE-70 main structure of the four straight fan side of the compact structure can accelerate the H- and D-
