Abstract: Superconducting wires are widely used for fabricating magnetic coils in fusion reactors. Superconducting magnet system represents a key determinant of the thermal efficiency and the construction/operating costs of such a reactor. In consideration of the stability of 11 B against fast neutron irradiation and its lower induced radioactivation properties, MgB 2 superconductor with 11 B serving as the boron source is an alternative candidate for use in fusion reactors with a severe high neutron flux environment. In the present work, the glycine-doped Mg 11 B 2 bulk superconductor was synthesized from isotopic 11 B powder to enhance the high field properties. The critical current density was enhanced (10 3 A·cm ?2 at 20 K and 5 T) over the entire field in contrast with the sample prepared from natural boron.
