A star will be bornA

star will soon be born, a star unlike any other… aman-made star. ITER – the Latin word for “The Way” –will light up in the middle of the coming decade.
From a scientific and technological point of view, it will
be one of humankind’s historic achievements. The creationof an artificial star and the tapping of the tremendous
amounts of energy produced could forever alter the courseof civilization.
The ITER Project, an unprecedented international
collaboration that brings together China, the European
Union, India, Japan, Korea, Russia and the United States, is theculmination of decades of research and years of diplomaticnegotiation. It has been the aspiration of three generations ofphysicists; it is now the reality of the hundreds of scientists,
engineers and labourers working in southern France where
the ITER installation is under construction.
The seven ITER Members, representing half the world’s
population, share the responsibility for building the ITER
machine and facilities. Every Member, essentially, isinvolved in every system.
As buildings rise on the ITER platform (pages 5 to 19),
component manufacturing advances in ITER Member
factories (pages 23 to 48).
This third edition of the ITER photobook aims to take you
into the heart of ITER – from the rolling hills of Provence tofactories on three continents, where men and women from
35 nations are bent on realizing one of mankind’s mostenduring dreams: capturing the fire of the stars andmaking it available to humanity for the millennia to come.

The ITER Tokamak

The ITER machine is a tokamak, the Russian acronym
for Toroidal Chamber, Magnetic Coils. Tokamaks weredeveloped in the 1960s at a time when nations wereexperimenting with all kinds of diﬀerent systems to
reproduce the nuclear reactions at work in the core of the
Sun and stars.
A tokamak, like a star, is designed to fuse light atoms
into heavier ones. A tokamak is a magnificent tribute toAlbert Einstein’s E=mc2: the tiny loss of mass that resultsfrom the fusion process translates into a huge quantity ofenergy. One gram of fusion fuel (the hydrogen isotopes
deuterium and tritium) generates as much energy aseight tonnes of oil.
ITER will be by far the largest and most complex tokamak
ever built. Designed from the experience accumulated byhundreds of fusion machines throughout the world, it will
demonstrate that fusion energy is scientifically andtechnologically feasible.

ITER ORGANIZATIONMANUFACTURING
A unique aspect of ITER implementation is the in-kind procurement system that wasestablished at the onset of the project. Instead of contributing purely financial resources,
China, the European Union, India, Japan, Korea, Russia and the United States will be providing
90% of their contributions in the form of machine components, systems and – in the case ofEurope – buildings.
Procurement packages are shared equally (~ 9% of the total value) between China, India,
Japan, Korea, Russia and the United States; Europe’s share, as Host Member, is ~ 45%.
The in-kind procurement arrangement is at the core of ITER's founding philosophy,
oﬀering the ITER Members invaluable experience in the manufacturing of components for afusion installation.
By contributing to the construction of the experimental machine, the ITER Members are
creating the technological and industrial basis for the commercial fusion reactors of the future.
