  • Th six-metre-tall structure currently on the shop floor in Ulsan is only the small upper segment of one of the nine ITER vacuum vessel sectors.

    Far from ITER, in the heart of the Tokamak

    In ITER Member factories on three continents, manufacturing has begun for the components of the ITER Tokamak. Here's a look inside the Hyundai shipyard in Korea where two of the nine ITER vacuum vessel sectors are under construction. [...]

  • Six years after the 9 November 1991 shot that produced fusion energy for the first time in history, JET achieved a record of 16 MW that still holds to this day. Pictured in this 1997 photograph are  Martin Keilhacker (right), at the time JET director, and his his two deputies (center) Alan Gibson and Jean Jacquinot.

  • At ITER, men and women of some 30 nations are inventing, day after day, a unique form of collaboration—one that serves science as much as it serves peace.

    Serving science, serving peace

    ITER has always been more than an international research project. When in the early 1980s scientists urged for the construction of a large machine that would d [...]

Welcome to the machine!

 (Click to view larger version...)
Tokamak: the name is an acronym from the Russian "toroidal chamber, magnetic coils." It describes a type of particularly efficient fusion machine that was developed by Soviet research in the late 1960s and adopted worldwide during the following decade.

ITER will be the largest and most powerful tokamak ever built. It is an assembly of 15 major systems, one million components and some 10 million individual parts (each one identified by a unique number for assembly purposes).

The assembly of the ITER Tokamak will begin in 2015 as the first components are delivered to the ITER site. The delicate process of installing and aligning parts weighing up to 1,250 tons, within absolutely minimal tolerances, will last about five years.
