【摘要】 电子冷却的应用提高了重离子储存环的束流品质,也为重离子储存环的运行带来了新的课题．电子冷却段的横向磁场在引导约束强流电子束的同时也不可避免影响了多次经过的离子轨道．为了保证束流的安全运行,必须将离子轨道的畸变部分限制在局部范围,并保证轨道畸变量对储存环接收度的影响可以容忍．讨论在建的兰州重离子储存环HIRFL-CSR电子冷却段磁场及其造成闭轨畸变和校正方案．更多还原

【Abstract】 Application of electron-cooling upgrades the quality of ion beams in the storage rings and brings new problems. The transverse magnetic field distorts the ion orbit while guiding the intense electron beam. The closed-orbit distortion should be and can be localized and controlled well inside the ring acceptance. This paper deals with the field in the e-cool section and concomitant COD of ion orbit and shows the correction scheme.更多还原
