Patent ID: 8745851

Claim:
A process for fabricating a low resistance superconducting joint with high shielding characteristics, comprising the steps of: corroding copper on an outer surface at an end of a niobium-titanium/copper (NbTi/Cu) superconducting wire to form terminal niobium-titanium (NbTi) superconducting filaments; inserting a niobium-titanium (NbTi) superconducting filament into each through hole of a niobium layer of a niobium/niobium-titanium/copper (Nb/NbTi/Cu) multilayer composite rod; pressing at an outside of the niobium/niobium-titanium/copper (Nb/NbTi/Cu) multilayer composite rod to combine the niobium/niobium-titanium/copper (Nb/NbTi/Cu) multilayer composite rod and the niobium-titanium (NbTi) superconducting filaments together to form a joint; and inserting the joint into a yttrium barium copper oxide (YBCO) tube, and then filling the YBCO tube with molten bismuth-lead-tin-cadmium (BiPbSnCd) alloy solder.
