Outline of Final Research Achievements |
High strengthened CuNb/Nb3Sn monolithic conductor and equivalent cross-sectional 8-strand Rutherford cable conductor have been fabricated, and the critical current properties for react&wind processed coils with coil bending strain of ε=0.42% have been evaluated at 15 K and 4 T. It is found that the critical current properties of a Rutherford cable coil are superior to those of a monolithic coil in the react&wind method. We succeeded in developing a 25 T cryogen-free superconducting magnet composed of the world's first react&wind CuNb/Nb3Sn Rutherford cable 14.0 T cryogen-free superconducting magnet. Concerning quench characteristic and thermal stability of a high-Tc RE123 coil, we obtained that the higher temperature operation for a high-Tc RE123 coil is the suitable condition in case of occurrence of the normal transition.
