Abstract

We succeeded in repairing YBCO coated conductors with local damage using the diffusion joint technique of stabilizing silver layers. A short piece of YBCO coated conductor was put on the damaged part in a face to face manner and joined by the diffusion technique. We also succeed in joining two multi-filament YBCO coated conductors (MFCCs) using the diffusion joint process. After the joint process, Ic was not reduced in any filament, resistance of the joint was low and practically constant in all the joined filaments, and resistance between two adjacent filaments was high enough.
