由牛津超导技术 (OST) 采用重叠棒工艺 (RRP) 生产的高性能 NbSn 绞线目前被认为是费米实验室加速器磁体研发计划的基准导体。为了提高磁体模型中预期电流和磁场范围内的线稳定性，线中子单元的数量增加了两倍（从 54 到 108），从而导致有效细丝尺寸更小。使用原始和变形股线样品研究了该设计的 1.0 和 0.7 毫米股线的性能。还使用超导变压器、小型跑道和 1 米壳式偶极线圈对由 1 毫米股线制成的 27 股卢瑟福电缆进行了测试。本文介绍了 RRP 绞线和电缆参数，并报告了绞线、电缆和线圈的测试结果。
The high performance NbSn strand produced by Oxford Superconducting Technology (OST) with the Restack Rod Process (RRP) is presently considered as a baseline conductor for the Fermilab's accelerator magnet R∓mp;mp;D program. To improve the strand stability in the current and field range expected in magnet models, the number of subelements in the strand was increased by a factor of two (from 54 to 108), which resulted in a smaller effective filament size. The performance of the 1.0 and 0.7 mm strands of this design was studied using virgin and deformed strand samples. 27-strand Rutherford cables made of 1 mm strand were also tested using a superconducting transformer, small racetrack and 1-m shell-type dipole coils. This paper presents the RRP strand and cable parameters, and reports the results of strand, cable and coil testing.
