AI Technical Summary
Existing high-performance superconducting wires have insufficient critical current characteristics in high magnetic field regions, and their mechanical and superconducting properties need to be improved.
By designing a superconducting wire precursor structure, Nb and Sn wires are stacked inside a Cu tube to form a honeycomb structure, and a thermally stable blocking layer and a Cu core are set inside. The area ratio of the Cu tube and the thermally stable blocking layer is optimized to promote uniform Sn diffusion and improve thermal stability.
It improves the mechanical properties and superconducting performance of superconducting wires, increases the critical current value and reduces hysteresis loss, and enhances stability in low magnetic field regions.
