The ITER 180-hectare site is located near Saint Paul-lez-Durance, southern France.

In the beginning of the 20th century, the potential energy of the atom was discovered.

The ITER 180-hectare site is located near Saint Paul-lez-Durance, southern France. Its main feature is a 42-hectare platform, one of the largest man-made levelled surfaces in the world. It measures 1 kilometre long by 400 metres wide, and its size could be compared to 60 soccer fields. There are 39 buildings, facilities and power supplies necessary for the operation of the biggest fusion machine on Earth.

Magnets

The ITER magnet system will be the largest and most integrated superconducting magnet system ever built. It will produce magnetic fields that will initiate, confine, shape and control the ITER plasma.

Vacuum Vessel

Plasma will be held inside a steel torus called a vacuum vessel. It was proven that the bigger the plasma volume, the better the confinement, so the ITER vacuum vessel will be really big.

Blanket

Blanket protects vacuum vessel from harsh conditions provided by fusion plasma. Because the vessel cannot be replaced, any damage to it will incur would cause termination of experiments.

Divertor

For a successful fusion reaction only the presence of fuel (deuterium and tritium in the case of ITER) in the plasma core is needed; all other particles, whether impurities or helium ash, are unwanted and need to be diverted away from the plasma, because they could cause energ…
