The joint Japanese-European fusion device JT-60SA (Japanese Torus-60 Super Advanced) will be the most powerful fusion device to date. Using superconducting magnetic confinement, JT-60SA will study advanced modes of plasma operation.

JT-60SA has been designed to support the operation of ITER by following a complementary research and development programme. The facility will also investigate how best to optimise the operation of fusion power plants that are built after ITER, including the demonstration fusion power plant DEMO.

JT-60SA is scheduled to begin scientific experiments in approximately two years. These will be jointly organised and run by Europe, represented by EUROfusion, and Japan.

JT-60SA is located in Naka, Japan at Japan’s National Institutes for Quantum Science and Technology (QST). The collaboration in JT-60SA results from an international agreement in the field of science between Europe and Japan, known as the “Broader Approach“.

A total of 500 researchers from Europe and Japan have been involved, and more than 70 suppliers have contributed to the manufacturing of its components. Works started in 2007 and were completed in 2020 with the end of assembly. Since then, a series of technical improvements were carried out, paving the way for the inauguration at the end of 2023.
