The NSE team successfully completes the various fabrication steps: assembling the 316LN tubes produced by Kobe Special Tube Co., Ltd.; inserting the dummy cable fabricated by Hitachi Cable at 2m/min; and eventually applying the compaction and the final spooling.

In the ITER vacuum vessel, 40-millimetre-thick shielding plates made out of borated stainless steel (type 304B7) with about two percent boron content will be used for neutron shielding. Manufacturing plates of this thickness is an industrial challenge, as steel with high boron content easily becomes hard and brittle. In recent tests performed under an ITER R&D contract, the Austrian company BÖHLER Bleche GmbH & Co KG, has proved it possible. Pictured: ultra-sonic inspection for volumetric defect detection.

ITER's D-shaped toroidal field coils will be encased in large stainless steel structures that will form the main support structure of the magnet system against gravity and electromagnetic loads during operation. A segment of toroidal field case is seen here in Japan (Kawasaki Heavy Industry), who has responsibility for nine toroidal field coils.

Tests for ITER's Test Blanket Module (TBM) program are run on the DIII-D Tokamak (General Atomics). The experiments test a candidate structural material for TBMs called EUROFER 97. TBM mock-up retracted from its enclosure outside a horiztontal port of DIII-D. Two racetrack-shaped electromagnets are shown that produce mainly toroidal field. They surround a solenoidal shaped coil that produces mainly vertical field.

Gyrotron prototypes like this one are under development for ITER in India, Russia, Japan and Europe (pictured: a 2MW gyrotron developed by Europe). In a gyrotron, beams of electrons are accelerated toward a cavity where a strong magnetic field is applied. The interaction between the rotating (cyclotron) motion of the electrons and the magnetic field generate high-frequency radio waves that "travel" in a straight line, almost like an optical beam. In ITER, the Electron Cyclotron Resonance Heating (ECRH) system will be composed of more than 20 gyrotrons that will deliver a combined heating power of 24 MW.

A real-scale prototype of DC busbars for ITER's poloidal field coil system is produced by the Russian Domestic Agency. Power in ITER will be fed to the different magnetic coils in the machine through water-cooled, eight-kilometre-long winding and bending aluminium busbars like this one. The prototype will be tested for current density, insulation, cooling requirements and temperature.
