Status of JT-60SA tokamak under the EU-JA Broader Approach Agreement

Abstract JT-60SA is a fully superconducting coil tokamakto be built under the framework of the EU-JA Broader Approach Agreement, and it aims to contribute to the complement of the ITER experiments and to the DEMO reactor design by the study of steady-state high-beta plasma experiments. The conceptual designof the JT-60SA tokamakand the peripheral systems has been carried out in close collaboration of EU and Japan from middle of 2006, and the JT-60SA Conceptual DesignReport which involves an analysis of plasma physics and engineering design is summarized in May 2007. This paper intends to present an overall view of the JT-60SA project, and the latest design status of the key engineering issues such as superconducting magnets, divertortarget, plasma heating devices, and magnet power supplies.
