Preparation Process of In Situ MgB2 Material with Ex Situ MgB2 Barrier to Obtain Long Sections of Superconducting Multicore Wires
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 MgB<sub>2</sub> core, an ex situ MgB<sub>2</sub> 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.
