增强器二极磁铁样机磁场测量rn与端部削斜研究

摘要

The field mapping of booster model dipole for SSRF is performed by taking point measurernments using the Hall probe, integrated field data is obtained by calculation of point measurement rernsults, and a study of pole ends chamfering is done for the integral field errors. The research results of rnpole ends chanffering measurement are presented in the paper and the dimensions of the pole end geomrnetry are determined. Finally, compared the three- dimensional field calculation results are compared rnwith the measured ones.%使用霍尔探头点测量上海同步辐射装置增强器二极磁铁样机场图，对点测结果rn进行数值积分得到场图中每条线积分，根据线积分误差分布，对极头端部进行削斜研rn究.本文给出了端部削斜磁场测量的研究结果，并且确定了样机磁铁端部的几何尺rn寸.最后用三维场模拟计算结果与实测结果作了比较.
