摘　　要：Septum magnet is one of the key components of synchrotron injection and extraction system.Because the excitation current flows through the septum plate coil,the excitation current is subjected to a large electromagnetic force.At the same time,under the limitation of the septum plate size,the leakage field has an effect on the circulating beam near the septum plate^([1]).There are several septum magnets in the HIAF accelerator complex,so the shielding structure needs to be optimized and analyzed to further reduce the losses caused by magnetic leakage.
