ITER—designed to demonstrate the scientific and technological feasibility of fusion power—will be the world's largest experimental fusion facility. The ITER Project is under construction in Saint-Paul-lez-Durance, in the south of France. The objective of the ITER project is to gain the knowledge necessary for the design of the next-stage device: a demonstration fusion power plant. In ITER, scientists will study plasmas under conditions similar to those expected in a future power plant. ITER will be the first fusion experiment to produce net power; it will also test key technologies, including heating, control, diagnostics, and remote maintenance.
ITER is also a first-of-a-kind global collaboration. Europe will contribute almost half of the costs of its construction, while the other six Members (China, India, Japan, the Republic of Korea, the Russian Federation and the USA), will contribute to the rest. The construction of ITER is managed by Domestic Agencies of the partners. The European Domestic Agency Fusion for Energy (F4E) has its headquarters in Barcelona (Spain).
