为 25 T 无制冷剂超导磁体开发了大口径 14-T CuNb/Nb3Sn 卢瑟福线圈。该磁体由 NbTi 和 Nb3Sn 卢瑟福线圈的低温超导 (LTS) 磁体和高温超导磁体组成。首次采用反应缠绕法制作了Nb3Sn卢瑟福线圈。 LTS 磁体在 1 小时斜坡率下无需训练失超即可达到 854 A 的设计工作电流。在 300 mm 冷孔中，霍尔传感器测量 LTS 磁体产生的中心磁场为 14.0 T、854 A。
A large-bore 14-T CuNb/Nb3Sn Rutherford coil was developed for a 25 T cryogen-free superconducting magnet. The magnet consisted of a low-temperature superconducting (LTS) magnet of NbTi and Nb3Sn Rutherford coils, and a high-temperature superconducting magnet. The Nb3Sn Rutherford coil was fabricated by the react-and-wind method for the first time. The LTS magnet reached the designed operation current of 854 A without a training quench at a 1 h ramp rate. The central magnetic field generated by the LTS magnet was measured by a Hall sensor to be 14.0 T at 854 A in a 300 mm cold bore.
