由于人们对使用超导Nb3Sn复合材料制造磁体以磁性约束聚变反应堆中的等离子体感兴趣，因此对超导Nb3Sn线材的制造技术和超导性能进行了广泛的研究。1，2如前所述，目前生产的纯Nb3Sn线材的使用似乎仅限于12 T或更低的磁场。然而，最近的设计，为未来的12T和托卡马克4型聚变反应堆要求磁铁在12 T或更高的磁场运行。因此，有必要提高电线的电流容量以满足这些未来的需求。
Because of the interest in the use of multifilamentary superconducting Nb3Sn composites for magnets to confine magnetically the plasma in fusion reactors, fabrication techniques as well as superconducting properties of multifilamentary Nb3Sn wires have been extensively examined.1,2As pointed out earlier, the use of pure Nb3Sn wires as currently produced appears to be limited for magnetic fields of 12 T or below. However, recent designs for future Mirror3and Tokamak4types of fusion reactors call for magnets operating at magnetic fields of 12 T or higher. Thus, it is necessary to improve the current capacity of the wires to meet these future demands.
