摘要
介绍了合肥光源(HLS)新注入系统中铁氧体磁芯冲击磁铁的脉冲磁场形态的设计与计算。首先根据注入过程跟踪计算,给出了冲击磁铁脉冲磁场的设计要求。然后对脉冲磁场的产生进行了定性分析和数值计算,讨论了在不同条件下磁芯中产生的涡流对脉冲磁场均匀性的影响,最后根据物理设计要求确定了磁铁设计参数。
The process of designing and computing the pulse field of kicker magnet with ferrite cores for new injection system of HLS storage ring is presented. Firstly, the requirement of field quality is derived from tracking study of injection course. Then, the generation of pulse field is qualitatively analyzed and numerically calculated and the effects of eddy currents in core on magnetic field homogeneity are discussed under different conditions. According to the results of the calculation and the requirement for field quality, the parameters of kicker magnet are determined.
