For REBa₂Cu₃O_y (REBCO) magnets operated in the persistent mode, the research and development of superconducting joints has progressed . Recently, we have evaluated the critical current of a joint (I_cj) using the decay of a current flowing in a closed loop with a superconducting joint. I_cj was evaluated for the intermediate grown superconducting (iGS) joint developed by Sumitomo Electric Industries, Ltd. We report the field angular dependence of I_cj in iGS joints.
