Preparation Process of In Situ MgB2 Material with Ex Situ MgB2 Barrier to Obtain Long Sections of Superconducting Multicore Wires
Year: 2024
Type: article
Abstract: In the present study, our emphasis was directed towards the fabrication process of long multi-core superconducting wires, each spanning several hundred meters. These wires feature an in situ MgB2 core, an ex situ MgB2 barrier, and a copper shield. The cost-effectiveness of these constituent materials, coupled with a judicious arrangement of internal components, facilitates the utilization of an economical shielding material for the resulting wire. Our ongoing efforts have successfully yielded several hundred-meter-long wire sections possessing favorable superconducting characteristics, making them suitable for self-field applications, such as direct current (DC) power lines.
