中文摘要	100MeV强流质子回旋加速器设计的引出质子束流强为大于200μA,并计划提供脉冲束流．轴向注入系统设计有两条注入线,即1#和2#注入线．1#注入线利用负氢束的中性化以解决强流连续束流的注入,为保证达到高中性化程度,横向聚焦均采用磁元件;2#注入线的设计目的主要是提供一定流强的脉冲化束流,由于脉冲化负氢束的中性化过程难以建立,因此,横向聚焦元件均为静电元件．两条线合理的结构设计使得注入系统可方便切换运行模式．采用包含空间电荷力的光学计算程序,匹配不同中性化程度的注入束流光学特性,匹配工作的重点在于高达40°的高频相位接收度．从离子源出口到粒子加速前15圈的连续匹配计算结果表明:所设计的注入系统可有效地控制束流包络,减少束流损失; 中心区高的高频接收度使设计的100MeV质子回旋加速器具有加速强流负氢束的能力．; A 100MeV high intensity cyclotron was designed to provide more than 200μA proton beam, and will provide pulse beam. The injection system has two considerations, which correspond to the 1# and 2# injection lines. The 1# line is designed to solve the DC beam injection using the neutralization with H-beam. For a high neutralization, the transverse focusing elements are all magnetic ones. The purpose of the 2# line is to provide pulse beam with certain intensity. It's difficult to build neutralization for the pulse beam, so the transverse focusing elements are all static electronic. The proper design for the structure of the two injection lines makes operation easy. Using computer program, including space charge effect calculations, we matched the injection optics for different neutralization degrees. The emphases of the calculations are getting 40° phase acceptance. The results calculated from the ion source to 15 turns acceleration show that the injection system designed for the 100MeV cyclotron can control the beam envelope efficiently and reduce the beam loss. The central region with the high RF phase acceptance makes the 100MeV machine have the ability of accelerating high intensity H- beam.; 国家自然科学基金(10125518)资助~~
