摘要：

Practical multifilamentary Nb3Sn wires with CuNbTi reinforcement (CuNbTi/Nb3Sn) exhibit the splendid mechanical tolerance of 340 MPa proof stress. We intended to develop a Nb3Sn coil by a react-and-wind method for a wide bore cryogen-free superconducting magnet, and made a react & wind coil employing CuNbTi/Nb3Sn wires. The performance test for the CuNbTi/Nb3Sn coil was carried out, and the coil generated 2.2 T at 180 A as the individual test. In the combination test in a background field of 5.6 T, the react & wind processed CuNbTi/Nb3Sn coil generated 7.5 T in a 220 mm room temperature bore. The wide bore cryogen-free superconducting magnet wound with highly strengthened CuNbTi/Nb3Sn wires is now being used for a high field heat-treatment equipment at 7 T. This wide bore furnace provides special heat-treatment conditions of high temperature 1500 'C in fields up to 7.0 T in a 40 mm sample bore.
