Abstract
The Karlsruhe Institute of Technology (KIT) has constructed and tested the High Temperature Superconductor Current Leads (HTS-CL) for the tokamak JT-60SA within the frame of the Broader Approach agreement between Europe and Japan. In total six HTS-CLs for 25.7 kA for the Toroidal Field (TF) coils and 20 HTS-CLs for 20 kA for the Equilibrium Field (EF) and Central Solenoid (CS) coils were manufactured and all of them were tested at operating temperatures in the test facility CuLTKa at KIT. After delivery, the CLs were integrated into the coil-terminal boxes (CTB) and connected to the TF, EF and CS coils via superconducting feeders. In the present paper the design, manufacture and acceptance tests of the HTS-CL at KIT, their integration into the CTBs, and first results of their operation during integrated commissioning are presented.
