CYCIAE-100是一台紧凑式回旋加速器,加速负氢粒子束,引出方式为双向剥离引出。在回旋加速器内部的加速平衡轨道上,由于磁场的对称性,束流是消色差的。加速的H-束流经过剥离膜剥离转换成质子后,将沿着引出轨道而被引出。由于磁场的非对称性和边缘场的存在,将会给引出的质子束流引入色散,造成水平的横向发射度增长。利用程序GOBLIN来计算从剥离膜位置到开关磁铁中心的束流色散的变化,比较不同位置处束流的色散效应,以进一步确认开关磁铁的位置,同时为后束运线的匹配打下基础。
CYCIAE-100 is a compact cyclotron, accelerate the negative hydrogen particle beam, leads to two-way peel leads. In the accelerating equilibrium orbit inside the cyclotron, the beam current is achromatic due to the symmetry of the magnetic field. The accelerated H-beam is peeled off the release film and converted into protons, which are led out along the lead-out path. As a result of the asymmetry of the magnetic field and the presence of the fringe field, dispersion will be introduced into the resulting proton beam, resulting in an increase in horizontal transmissivity. The program GOBLIN was used to calculate the dispersion of the beam from the position of the peel-off film to the center of the switching magnet. The dispersion effect of the beam at different positions was compared to further confirm the position of the switching magnet and to lay a foundation for the matching of the posterior bundling line.
