The upgrade of the JT-60U magnet system to the superconducting coils (JT-60SA) is progressing as a satellite facility for ITER by both parties of Japanese government and European commission (EU) in the Broader Approach agreement. Helium refrigerator, high temperature superconducting current leads and thermal shield are key components to keep superconducting magnet at 4.5 K. This report shows the manufacturing and installation status of cryogenic components for the JT-60SA.
