| Research Abstract |
A Walters' spiral apparatus was developed. Using the apparatus, a degradation of critical current, which is the maximum transport current, can be investigated for Nb_3Sn superconductor as a typical A15 superconductor for a high magnetic field use. A practical Nb_3Sn superconductor was soldered onto the Walters' spiral and immersed in liquid helium in an 18-T superconducting magnet. The transport current and the magnetic properties were investigated at 4.2K, 18T. 1.0% strain application caused a remarkable degradation in transport current property. However, a clear change in magnetic property was not observed.
