The JT-60SA device


What is JT-60SA?

JT-60SA is a fusion experiment designed to support the operation of ITER and to investigate how best to optimise the operation of fusion power plants that are built after ITER. It is a joint international research and development project involving Japan and Europe, and is to be built in Naka, Japan using infrastructure of the existing JT-60 Upgrade experiment. SA stands for "super, advanced", since the experiment will have superconducting coils and study advanced modes of plasma operation. Further details of its experimental programme are explained in the JT-60SA Research Plan.

What is fusion?

Fusion is the energy source of the sun and the stars. On earth, fusion research is aimed at demonstrating that this energy source can be used to produce electricity in a safe and environmentally benign way, with abundant fuel resources, to meet the needs of a growing world population.
