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, I_c 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.
