如何处理给定磁场和孔尺寸下的临界电流是磁体设计者非常关心的问题。在高温超导磁体的情况下，BSCCO ag包覆磁带缠绕，它们具有很强的磁各向异性，因此磁铁的临界电流由整个线圈的平均电压降定义，不像低温超导磁体那样容易确定。基于BSCCO银包带的实测数据，通过电场和磁场分析，提出了一种获得高温超导磁体临界电流的解析方法。通过追求最佳线圈截面，研究了高温超导磁体的性能改进。
It is of great concern for magnet designers to address their critical currents at a given field and bore size. In the case of high temperature superconducting magnets wound with BSCCO Ag-sheathed tapes, they have a strong magnetic anisotropy and therefore the critical current of magnets defined by an average voltage drop over an entire coil cannot be easily determined like low temperature superconducting magnets. An analytical way to obtain the critical current of HTS magnets is described by means of the electric and magnetic field analyzes based on the measured data of BSCCO Ag-sheathed tapes. A performance improvement of HTS magnet is studied by pursuing an optimum coil cross section.
