“This is a breakthrough for the fusion community. We have successfully tested and demonstrated a key technology milestone which is integral to the success of ITER. Based on these achievements, Europe, Russia and China will proceed with the procurement of the ITER Poloidal Field conductor” said Fusion for Energy Director, Didier Gambier.
The test coil with an outer diameter of 1.5 m and weighing 6 tons was the product of an international collaboration between Russia, Europe and Japan.
Russia produced the 0.73-mm diameter Nb-Ti superconducting strands and bundled them into a cable consisting of 1,440 strands. Europe assembled the cable into a steel jacket to make the final conductor and was also responsible for winding the conductor, insulating the turns and bonding them together to form a coil.
Japan was in charge of testing the coil at the JAEA site in Naka because of its world class expertise with a team of experts from the ITER Organisation, Europe, Japan, Russia and the United States. The results gave scientists complete confidence that this conductor would fulfill the extremely demanding performance required for ITER.
ITER will be the world's largest experimental fusion facility to demonstrate the scientific and technological feasibility of fusion power. Fusion is the process which powers the sun and the stars. When light atomic nuclei fuse together to form heavier ones, a large amount of energy is released. Fusion research is aimed at developing a prototype fusion power plant that is safe, environmentally responsible and economically viable with abundant fuel resources.
Europe will contribute almost half of the costs of its construction, while the other six Members to this joint international venture (China, India, Japan, the Republic of Korea, Russia and the United States), will contribute equally to the rest. The site of the ITER project is at Cadarache, France.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
