Outline of Final Research Achievements

Magnesium diboride (MgB2) superconducting wire has potentially excellent characteristics, and it offers an exciting opportunity for the development of lightweight, space-saving, and low-cost magnetic resonance imaging (MRI) scanners. The practical realization with reliable performance including a persistent-mode operation, however, still requires further enhancement of the transport critical current property and the development of MgB2-based technology. Here, we undertook the study and attempted to improve the superconducting properties of MgB2 wires, joints, and coils. Some of the wires were fabricated with carbon doping, which improves the in-field critical current density, and the superconducting joints between the two carbon-doped mono-core wires achieved current carrying retention in the joint of up to about 70% compared to wire without a joint. MgB2 coils were also fabricated via the wind and react method, and the persistent-mode operating states in solid nitrogen were evaluated.
