Superconducting wire, method of manufacturing superconducting wire, superconducting coil, superconducting magnet and superconducting device

摘要

A superconducting wire comprises: a first wire with a first superconducting material layer with a first main surface, a second wire with a second superconducting material layer with a second main surface, a third wire with a third superconducting material layer with a third main surface, a first connection layer made of superconducting material , which connects the first main surface to the second main surface, and a second connection layer made of superconducting material, which connects the second main surface to the third main surface. The first wire has a first end face. The third wire has a second end face. The second end surface lies opposite the first end surface, a distance being provided between the second end surface and the first end surface. The distance is greater than or equal to 10 nm and less than 1 mm.
