摘　　要：A 100MeV compact high intensity H-cyclotron is under design and construction at CIAE which will provide a 75MeV—100MeV,200μA proton beam.The main magnet of this cyclotron adopts an integrally compact structure with a fixed field and four sectors,while the hill gap is constantly changeable.This paper reviews the design features of the magnet,numerical simulation results,the inner defects of the magnet including the carbon content segregation and shrinkage porosity,factors related to mechanical design including the tolerance and deformation.The latest progress will also be reported in this paper.中国原子能科学研究院目前正在建造一台100MeV强流回旋加速器,它加速负氢离子,通过剥离引出质子束,能量75MeV—100MeV,流强200μA.该回旋加速器的主磁铁为紧凑型整体结构,采用4扇直边叶片,渐变气隙.将报告该磁铁的设计特点,数值模拟结果;磁性材料及成分偏析、缩孔等内部缺陷;机械结构设计、公差、变形;还将描述磁铁的工作进展.
