Properties of Superconducting wires for Neutron Irradiation

The improvement of critical current property as well as the mechanical property is important for the application. The improvement of the critical current can be achieved by forming the nano size defect working as a flux pining center inside the superconductor. The nano size defect can be effectively formed by using neutron iradiation. All properties of most of materials after irradition become bad On the contrary, the critical current property of the superconductor is largely improved after irradiation.
