A Rutherford-type cable is one of candidate conductors for a large-scale or high-field superconducting magnet. It is important to evaluate the internal strain state of strand consisting of a cabling conductor to understand the strain dependence of superconducting properties. Internal lattice strains under a tensile load for Nb-rod-processed Nb 3 Sn Rutherford cable with and without the prebending treatment were measured directly by neutron diffraction at room and low temperatures. Stress-lattice strain curves of Nb 3 Sn were obtained, and it was found that the internal lattice strain is smaller than the strain measured on the cable surface by an extensometer above 100 to 150 MPa. It is important to evaluate not only the strain on the cable surface but also the internal strain of a strand in cabling conductors.Index Terms-Internal strain, Nb 3 Sn, neutron diffraction, Rutherford cable.

“…The transport and mechanical properties of the CuNb/ Nb 3 Sn Rutherford cable were evaluated by a performance test of the monolayer coil in high fields [13,14]. The Rutherford cable, composed of 16 CuNb/Nb 3 Sn strands, demonstrated a good performance under large electromagnetic stress in high fields.…”

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.
