The tokamak is an experimental machine designed to harness the energy of fusion; inside a tokamak, a fusion plasma is created and confined by strong magnetic fields. The energy produced through the fusion of atoms in the plasma is absorbed as heat in the walls of the vessel.
Conceived at the very frontier of what is possible to design, manufacture, and assemble, the ITER device—a tokamak—will be the world’s largest and most powerful, capable of creating a “little star” on Earth.
The seven-storey structure will house not only the ITER Tokamak, but also more than 30 different plant systems that are necessary for the machine's operation. The Tokamak Complex is a nuclear-rated structure of reinforced concrete that is supported on aseismic isolators.
One million components, ten million parts; find out more about the ITER tokamak and its systems by choosing a section below. Top ITER ("The Way" in Latin) is one of the most ambitious energy projects in the world today.
Le Complexe tokamak, un édifice de 440 000 tonnes constitué par les Bâtiments tritium, tokamak, et diagnostics, forme le cœur de l'installation scientifique ITER. Long de 120 mètres, large de 80 et culminant à une hauteur de 80 mètres (60 mètres au-dessus de la plateforme), le Complexe tokamak domine la plateforme ITER de toute sa masse.
China's Experimental Advanced Superconducting Tokamak (EAST) has made an important advance by achieving stable 1056-second steady-state high-temperature plasma operation, setting a record for long-pulse operation on the night of 30 December 2021.
Le tokamak est une machine expérimentale conçue pour exploiter l'énergie de la fusion. Elle permet de créer et de confiner un plasma de fusion grâce à des champs magnétiques intenses. Dans l'enceinte d'un tokamak, l'énergie générée par la fusion des noyaux atomiques est absorbée sous forme de chaleur par les parois de la chambre à ...
The SST-1 plasma carries all the standard attributes of tokamak plasma in contemporary devices. SST-1 is also the only tokamak in the world with superconducting toroidal field magnets operating in two-phase helium instead of supercritical helium in a cryo-stable manner, thereby demonstrating reduced cold helium consumption.
The ITER Tokamak will be the largest ever built, with a plasma volume of 830 cubic metres. The maximum plasma volume in tokamaks operating today is 100 cubic metres—reached in both Europe's JET and Japan's JT-60.
Thirty-nine buildings and technical areas house the ITER Tokamak and its plant systems. The heart of the facility—the Tokamak Building—is a seven-storey structure in reinforced concrete that sits 13 metres below the platform level and 60 metres above.
