After only a few weeks of operation, Hydrogen plasmas with 2-3 x 10E19 m-3 line integrated plasma density, 7.5 keV central electron temperature, 1 keV line-averaged ion temperature could be achieved with only 2.5 MW 140 GHz ECR heating power. Initial experiences and first results of Helium and Hydrogen plasma operation are summarized. In the end of 2015 the first Helium plasmas were created and soon after, Hydrogen plasma operation was started.Ī brief overview of the construction and commissioning history of W7-X is given. The commissioning was successfully concluded by the measurement of the magnetic flux surfaces, which has fully confirmend the basic magnetic field topology.
After about one year of commissioning (pump-down, cool-down, magnet ramp-up), the device was ready for operation. The construction of W7-X took 15 years and was completed in mid 2014. The design of W7-X is based on the optimization of the geometric properties of the magnetic field with the aim to minimize neoclassical transport losses in the collisionless regime, to provide good fast ion confinement in the centre of the plasma, to achieve satisfactory equilibrium and stability properties at high β, and to demonstrate viable divertor operation.
This is to establish the optimized stellarator as a viable fusion power plant concept. The optimized stellarator Wendelstein 7-X (W7-X) has started with the goal to demonstrate steady-state plasma operation at fusion relevant plasma parameters. Keywords: Fusion, Tokamak, Burning Plasma, Superconductivity, Vacuum Vessel, Cryostat, Nuclear Safety The presentation will review the progress made in developing the advanced technologies required for ITER, the measures taken to establish a more effective project organization and the status of construction of the ITER facility. To meet the challenges associated with the management of the manufacturing and construction activities, the overall project organization has been strengthened, with a tighter integration between the ITER Organization Central Team and Domestic Agencies. With on-site construction of the Assembly Hall and Tokamak nuclear complex advancing rapidly, the organizational framework for the initial installation and assembly activities has been defined. R&D prototyping and testing of major elements of systems such as plasma facing components, heating and current drive systems, remote handling and power supplies are also at an advanced stage. Fabrication of the vacuum vessel and thermal shield is moving forward, while the first elements of the cryostat (~29 m diameter x ~29 m height) have been delivered to the ITER site. The international collaboration formed around the production of superconducting magnets for the ITER tokamak has produced over 600 t of Nb3Sn and almost 250 t of NbTi superconducting strand, with 80% of the superconductors required for the ITER magnets now complete, and coil fabrication activities underway in 6 of the 7 partners’ factories.

Supported by impressive achievements in fusion technology R&D, manufacturing of ITER components is in full swing across the world and the facility is taking shape at St-Paul-lez-Durance. We look forward to seeing you at SOFT 2016 in Prague, The City of a Hundred Spires!Ĭhairman of the Local Organizing CommitteeĬhairman of the International Organizing CommitteeĮstablished by the signature of the ITER Agreement in November 2006, the ITER project is a critical step in the development of fusion energy: its role is to confirm the feasibility of exploiting magnetic confinement fusion for the production of energy for peaceful purposes by providing an integrated demonstration of the physics and technology required for a fusion power plant. Prague offers you a unique combination of charming, mysterious and inspiring atmosphere of one of the most preserved historic cities in Europe with the modern infrastructures and lively spirit of growth and development. SOFT includes oral and poster presentations as well as industrial and R&D exhibitions. It regularly attracts more than 800 scientists, engineers, industry representatives and exhibitors from all over the world and focuses on the latest developments on running and planned fusion experiments. The biennial Symposium on Fusion Technology is the leading conference in this field in Europe. The event is organized jointly by the Institute of Plasma Physics of the CAS and the Research Centre Rez, two principal institutes engaged in the research of thermonuclear fusion and fusion technologies within the Czech Republic. We cordially invite you to take part in the 29th edition of the Symposium on Fusion Technology (SOFT 2016) that will be held for the first time in Prague, Czech Republic, from 5th to 9th September 2016.
