What is JT-60SA?

JT-60SA is a joint international fusion experiment being built and operated by Japan and Europe, in Naka, Japan, using infrastructure of the previous JT-60 Upgrade experiment alongside new hardware. SA stands for “super, advanced”, since the experiment will have superconducting coils and study advanced modes of plasma operation.

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.

What will JT-60SA contribute?

JT-60SA has been designed to support the operation of ITER by following a complementary research and development programme, and to investigate how best to optimise the operation of fusion power plants that are built after ITER. Further details of its experimental programme are explained in the JT-60SA Research Plan.
