在NIMS和Fermilab的合作下，我们使用Nb矩阵和Ta矩阵股线制造了铜稳定的Nb3Al卢瑟福电缆。首先，这些电缆进行了研究，在高电流在低自场使用磁通泵。使用这些卢瑟福电缆，我们建立和测试小型跑道磁铁。用铌基股线制成的磁体在低磁场下表现出磁通跳跃不稳定性。用Ta基质Nb3Al卢瑟福电缆缠绕的小型跑道磁体在4.5 K操作时非常稳定，没有任何不稳定性，以及在2.2 K操作时。随着小型跑道磁体在短样本数据下的成功运行，确立了Nb3Al股线及其卢瑟福电缆应用于高场磁体的可行性。比较了Nb_3Al卢瑟福电缆和Nb_3Sn卢瑟福电缆的特性，讨论了Nb_3Al卢瑟福电缆的优点。
In collaboration between NIMS and Fermilab, we have made copper stabilized Nb3Al Rutherford cables, using Nb-matrixed and Ta-matrixed strands. First these cables were investigated at high current in low self field using a flux pump. Using these Rutherford cables, we built and tested small racetrack magnets. The magnet made with the Nb-matrixed strand showed the flux jump instability in low field. The small racetrack magnet wound with the Ta-matrixed Nb3Al Rutherford cable was very stable at 4.5 K operation without any instability, as well as at 2.2 K operation. With the successful operation of the small racetrack magnet up to its short sample data, the feasibility of the Nb3Al strand and its Rutherford cable for their application to high field magnets is established. The characteristics of Nb3Al Rutherford cable is compared with that of the Nb3Sn Rutherford cable and the advantages of Nb3Al Rutherford cable are discussed.
