摘　　要：MgB2作为超导材料中的一颗新星,可以很好的应用于超导磁体。文中对比分析了作为超导磁体应用材料MgB2的超导特性,之后进行了MgB2磁体电磁设计。并通过与已有的Bi系超导磁体的对比,论证了MgB2在超导储能磁体应用中的可行性。针对MgB2超导特性进行磁体结构优化设计,得到两种新思路的螺管型磁体模型,都能够达到更好的经济性。As a new star of superconducting materials, MgB2 can be well applied in superconducting magnet. The paper have introduced the superconducting of MgB2 and its superiority as the material of superconducting magnet. After electromagnetic design, the point that MgB2 is applicable for SMES is proved by contrasting with the Bi -2223 superconducting magnet. The proposed configuration is optimized according to the superconductivity of MgB2, and then we can get two solenoid models of new type,which are cheaper than the original sample.
