采用Nb/sub 3/Sn纤维增强型导线制作了超导线圈并进行了测试。导线的每根超导细丝都由钽纤维加强。线圈是在缠绕和反应过程中制备的，并通过环氧树脂浸渍完成。电线的连续长度为250米，其中100米用于线圈。在液氦中的淬火电流达到了类似的水平，没有退化的电线短样品的临界电流。应变对工作电流的依赖关系进行了描述，并与使用二维分析的计算进行了比较。作为参考，制备并测试了使用具有类似规格的内部加强丝的另一个弹簧圈。
A superconducting coil using a Nb/sub 3/Sn fiber-reinforced type of wire was fabricated and tested. Each superconducting filament of the wire was reinforced by a tantalum fiber. The coil was prepared in a wind-and-react process and was completed by epoxy impregnation. The continuous length of the wire was 250 meters, and 100-meters of it were used for the coil. The quench current in liquid helium reached similar levels to the critical current of the short sample of the wire without degradation. The strain dependence on operating current was described and compared with calculations using two-dimensional analyses. As a reference, another coil using an internally reinforced wire with the similar specifications was prepared and tested.
