Title:
SUPERCONDUCTING WIRE, SUPERCONDUCTING COIL USING SAME, AND MRI
Document Type and Number:
WIPO Patent Application WO/2020/090259
Kind Code:
A1
Abstract:
The present invention addresses a problem of providing an MgB2 wire material having a small allowable bending radius, a superconducting coil using the same, and an MRI without lowering a critical current value and a critical current density of the MgB2 wire material to an extreme. To solve the problem, provided are a superconducting wire having a plurality of MgB2 strands and a first base metal, a superconducting coil using the same, and an MRI, the superconducting wire being characterized in that in a cross section orthogonal to a wire longitudinal direction, a center point of an area surrounded by the plurality of MgB2 strands and a center axis of a cross section of the superconducting wire are disposed in separated positions.
