Des pièces d'acier hautes comme un immeuble de quatre étages et pesant plusieurs centaines de tonnes qui s'ajustent avec une précision inférieure au quart de millimètre, c'est un exploit industriel.

In southern France, 33 nations* are collaborating to build the world's largest tokamak, a magnetic fusion device that has been designed to prove the feasibility of fusion as a large-scale and ...

Standing six storeys high in the Assembly Hall, the 800-tonne tools suspend the vacuum vessel sectors while carefully positioning and installing—via the rotary motion of the "wings"—thermal shield ...

ITER Annual Report and more: Downloadable documents from ITER including the latest brochures, posters, photo books, financial reports.

The heart of a tokamak is its doughnut-shaped vacuum chamber. Inside, under the influence of extreme heat and pressure, gaseous hydrogen fuel becomes a plasma—a hot, electrically charged gas. In a ...

The amount of fusion energy a tokamak is capable of producing correlates directly to the number of fusion reactions taking place in its core. Scientists know that the larger the vessel, the larger the ...

The fusion process at ITER requires tritium, a radioactive form of hydrogen with a half-life of 12.3 years. Although the amount of tritium used during plasma pulses is very small—only a few grams at ...

Qualitatively, the Q of ITER signifies the achievement of a "burning plasma"—a state of matter that has never been produced on Earth and that will usher in a new era of fusion research. In a burning ...

The ITER remote handling systems comprise a large array of robotic transporters, manipulators, tooling and support structures deployed within the ITER machine, the Tokamak Building, and the Hot Cell ...

JET—the Joint European Torus*, used by 4,800 EUROfusion consortium experts, students and staff from across Europe—has set a world record for the most energy produced in a single fusion shot, ...

ITER's most powerful external heating system—neutral beam injection—will be tested in advance of operation at the Neutral Beam Test Facility (NBTF) in Padua, Italy. Although neutral beam injection is ...

ITER will be equipped with a cooling water system to manage the heat generated during operation of the tokamak. The internal surfaces of the vacuum vessel (first wall blanket and divertor) must be ...
