由牛津超导技术公司（OST）生产的高性能Nb 3Sn股线，采用Restack棒工艺（RRP）和127 Restack设计，是目前费米实验室加速器磁体研发计划中使用的基线导体。在证明了这种方法在减少子单元合并方面的有效性后，通过增加子单元之间的Cu厚度进一步提高了原始RRP-127设计的稳定性[1-3]。生产了许多不同横截面的RRP-127坯料（RRP-102/127、RRP-108/127和RRP-114/127），以优化成缆过程中股线塑性变形的设计。使用原始和变形钢绞线样本研究了这些新钢绞线的性能，并与RRP-54/61堆叠设计的性能进行了比较。还生产了由0.7mm股线制成的卢瑟福电缆，用于高场四极杆。本文介绍了RRP-127钢绞线的开发以及钢绞线和缆索分析的结果。
The high performance Nb3Sn strand produced by Oxford Superconducting Technology (OST) with the Restack Rod Process (RRP) and a 127 restack design is the baseline conductor presently used in the Fermilab’s accelerator magnet R&D program. The original RRP‐127 design was further improved in stability by increasing the Cu thickness between subelements after proving the effectiveness of this method in reducing subelement merging [1–3]. A number of RRP‐127 billets of various cross sections (RRP‐102/127, RRP‐108/127 and RRP‐114/127) were produced to optimize the design with respect to strand plastic deformation during cabling. The behavior of these new strands was studied using virgin and deformed strand samples, and compared with that of the RRP‐54/61 stack design. A Rutherford cable made of 0.7 mm strands was also produced to be used in high field quadrupoles. This paper describes the RRP‐127 strand development, and results of strand and cable analyses.
