摘　　要：中国原子能科学研究院建成了100 MeV紧凑型强流质子回旋加速器,其引出能量为75~100 MeV,流强为200~500μA。为了减小粒子加速时束流损失并满足加速器粒子对真空的要求,文中设计了一个内径为4040 mm、高度为1270 mm的主真空室来保证加速器的真空。介绍了主真空室结构设计的难点,并对应力分析情况、放射性防护方面设计进行了介绍。The cyclotron built in China Institute of Atomic Energy is a high intensity and compact proton cyclotron with extracted beam of 75~10O MeV and designed current of 200~500μA.In order to reduce the beam loss during particle acceleration and meet the requirements of vacuum for the accelerator particles,a main vacuum chamber with an inner diameter of 4040 mm and a height of 1750 mm is designed to ensure the vacuum of the accelerator.This paper mainly introduces the difficulties in the structural design of the main vacuum chamber,and gives a detailed introduction to the stress analysis and the design of radiation protection.
