Abstract
Multifilamentary (Nb,Ti)3Sn superconducting wires with reinforcing stabilizer of CuNb composite, CuNb/(Nb1Ti)3 Sn, were developed. Previously, we researched on the effect of reinforcement of CuNb composite as a CuNb/(Nb, Ti)3 wire and its stability by investigating the MQE(minimum quench energy). A test coil was was fabricated using this reinforced wire without extra reinforcing material. The coil was produced by the “react and wind method”, then electromagnetic force for the wire was applied by charging electric current in the coil up to 11T. The coil was energized successfully and the generated electromagnetic force for the wire reached 224 MPa at 136 A and 9 T without any degradation of test coil. These results proved that the bronze processed multifilamentary CuNb/(Nb,Ti)3Sn wires have an excellent mechanical property, and a possibility to realize compact design of future superconducting magnet was confirmed
