“…Thus, high-strength Nb 3 Sn wires or cables are needed in highfield magnets. For example, a CuNi-NbTi reinforced Nb 3 Sn wire was developed for an outsert superconducting magnet for a 28 T cryogen-free hybrid magnet at the High Field Laboratory for Superconducting Materials, Institute for Materials Research, Tohoku University in Japan [3,4], and cable-in-conduit conductors were used for an outsert superconducting magnet of a 45 T and 36 T hybrid magnet at the National High Magnetic Field Laboratory in the USA [5]. On the other hand, a Rutherford cable is used for accelerator magnets.…”

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.
