Abstract

Multifilamentary (Nb,Ti)₃Sn super-conducting wires with reinforcing stabilizer of CuNb composite, CuNb/(Nb,Ti)₃Sn, 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 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 224MPa at 136A and 9T without any degradation of test coil. These results proved that the bronze processed multifilamentary CuNb/(Nb,Ti)₃Sn have an excellent mechanical property, and a possibility to realize compact design of future superconducting magnet was confirmed.
