As a divertor heat removal component of a fusion device, tungsten (W) and chromium-zirconium-copper (CuCrZr) joints were fabricated by the discharge plasma sintering (SPS) method. The thermal stress relaxation layer of W-Cu mixed powder was confirmed to have sufficient density. A test piece was fabricated using the proposed method and installed in the divertor section of a large helical device LHD. The results of the infrared camera during the experiment and the damage after the experiment are also reported.
