Every second, our Sun turns 600 million tons of Hydrogen into Helium, releasing an enormous
amount of energy. In ITER, the fusion reaction will be achieved in a Tokamak device, a next
generation fusion machine that uses magnetic fields, including large superconducting magnets,
to contain and control the hot plasma. The fusion between Deuterium and Tritium (D-T) will
produce one Helium nuclei, one neutron and energy. The energy will be transformed into heat,
which will be used to produce steam and - by way of turbines and alternators – electricity.
The purpose of ITER is to establish one of the largest and most ambitious international science
projects ever conducted with the contribution of its seven international Members.
The signature process of the Global Insurance Contract that covers the construction and
assembly of the ITER plan was finalized on November 30th 2010.

Objectifs de contrôle:
Optical sensing systems to measure strain, displacement and temperature in the cryogenic
environment found in the ITER magnets. The ITER project is a large-scale scientific experiment that aims at developing a new, cleaner, sustainable source of energy, by producing energy from fusion - the process that occurs at the core of the Sun.
The porject foresees to provide Optical Sensors based on FBG (Fiber Bragg Grating)
technology, Fabry-Perot interferometers and laser distance meters, under the scope of the international ITER project for fusion.
Strain, displacement and temperature optical sensors will be installed on the structures of the Toroidal Field Coils, Central Solenoid, Correction Coils and Poloidal Field Coils. The first phase of the work includes the adaptation and qualification of sensors, measurement units and software for the particular constraints of the ITER superconducting magnets (cryogenic temperatures, high magnetic field and stron raditation doses). A second phase will consist of series production and delivery of the sensing systems, which is foreseen to happen in early 2012. In total, the two contracts foresee the sale of approximately 500 to 900 sensors and the related data acquisition systems, as well as complementary accessories such as cables and software.
