This Procurement Arrangement is for part of the conductor for the 18 Toroidal Field (TF) Coils that will confine the plasma within the ITER machine. “Being the first Procurement Arrangement, it clearly signals that ITER procurements have begun and on a big scale”, Kaname Ikeda, ITER Director General, said.
With the manufacture of approximately 400 tons of niobium3-tin (Nb3Sn) conductor cables it is one of the largest superconducting cable procurements in history. “The amount of material that is going to be manufactured is certainly unprecedented in its scale and it signals the first step in the construction of the ITER magnets”, Neil Mitchell, responsible officer for the ITER Magnet System said.
The ITER TF coils are designed to have a magnetic energy of 41 Giga Joule and a maximum magnetic field of 11.8 tesla. Their design is the result of an international research and development effort. The manufacture of these strands with about 10000 micron-scale filaments per strand is extremely complex and uses cutting-edge technology. The cable has been developed through a series of tests on different designs. Performance checks and quality control during the production process will be of the highest importance for the success of ITER.
About 90% of the ITER components and structures are provided “in kind” by the Members, through the Domestic Agencies. Following this Agreement, ten of the 18 coil winding packs for ITER will be produced in Europe, including one spare. The nine to be produced in Japan are the subject of today’s signature.
Toshi Nagaoka expressed his satisfaction at being part of the first signing ceremony and stated that signature of the Procurement Arrangement will now allow the Japanese Domestic Agency to start the procurement for ITER.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
