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.

NASA keeps watch over space explosions

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
