文摘High homogeneity of the CR (collector ring) dipole magnet for FAIR (Facility for Antiproton and Ion Research) project at GSI is essential.The two optimized and analysis methods are introduced in detail,In order to obtain an ideal integral magnetic field distribution,the complicated end chamfer has been designed.By chamfering the removable pole,the distribution tolerance of high magnetic field is optimized to±2×10^(-4).The method of adding a mirror plane is suitable for the high magnetic field and it doesn't fit the low one.The OPERA is used to optimize the dipole magnetic field.
