摘要
对混合型短周期摇摆器磁场进行了解析求解,给出了与摇摆器周期、间隙、磁块性能、磁场尺寸以及磁极尺寸等相关的二维解析表达式。根据该公式,作者讨论了混合型短周期摇摆器产生强磁场的潜在能力,提出了一系列改进方法,并分别进行了模型实验,实验结果与理论分析相符合。目前,在1cm周期、5mm间隙的短周期摇摆器模型试验中,中心轴峰值磁感应强度已达到0.45T。另外,该短周期摇摆器可进行单磁场磁场调节,最大峰峰值磁场相对误差小于1％。
This paper discribe the two -dimention analystic relationship of hybrid microwiggler field, and analyse the possibility of the hybrid microwiggler with high field. It is shown that the hybrid microwiggler with 10mm period and 5mm gap may generate 0.75T magnetic field on axis before the saturation of the poles. Moreover, we have given a discussion of several new methods for obtaining the high field and the results of the ecperimental models.
