Navigation menuRetrieved 16 May As of [update] , the Wendelstein 7-X reactor is the largest stellarator device. Then, on 3 February , production of the first hydrogen plasma initiated the science program. A system of sensors and probes based on a variety of complementary technologies will measure key properties of the plasma, including the profiles of the electron density and of the electron and ion temperature, as well as the profiles of important plasma impurities and of the radial electric field resulting from electron and ion particle transport.
Planning initiated  . Jan 12, A view inside the Wendelstein 7-X plasma vessel with graphite tile cladding.
Your email. Installation of the new ones can now begin," said Hans-Stephan Bosch, whose division is responsible for technical operation of the device. Your feedback will go directly to Science X editors.
It will now be possible to raise the energy to 80 megajoules once all versions of the microwave heating have been tackled and tested, as compared with 4 megajoules in The installation of water-cooled inner cladding of the plasma vessel will make the facility suitable for higher heating power and longer plasma pulses.

September 11, The extension has made the device fit for higher heating power and longer pulses. This now allows the optimised concept of Wendelstein 7-X to be tested. Wendelstein 7-X, the world's largest fusion device of the Wenndelstein type, is to investigate its suitability for a power plant. Besides new heating and measuring facilities, over 8, graphite wall tiles and ten divertor modules have been installed in the plasma vessel since March last year, i.
This cladding is to protect the vessel walls and allow higher temperatures and plasma discharges lasting 10 seconds in forthcoming experiments. A special function is exercised here by the ten sections of the divertor: As broad strips on the wall of the Wendeelstein vessel, the divertor tiles conform exactly to Wendelstein 7 twisting contour of the plasma edge.
They thus protect especially those wall areas to which particles escaping from the edge of the plasma ring are specifically directed. Along with unwanted impurities the impinging particles are neutralised and pumped off. The divertor is thus an important tool for regulating the purity and density of the plasma.
But not till the Wendelsstein larger successor, Wendelstein 7-X at Greifswald, did the geometry conditions come up to power plant size, particularly the ratio of the divertor area to the Wendeltein volume. Newly enlisted measuring instruments will also Wendelsteln observation of turbulence in the plasma for the first time: Boesche Gewinnkontor small eddies entailed influence how successful magnetic confinement and Wendelstien insulation of the hot plasma are, these Nebenjob Lebenslauf important parameters for a future power plant, because they determine the size of the plant and Wendelstein 7 its economical Abschiedsbrief Englisch. In comparison with previous devices, Wendelstein 7-X is expected to yield quite new, possibly even better, conditions", says Thomas Klinger.
As all ten microwave transmitters for the microwave heating of the plasma are meanwhile Wendlstein for use, this will allow a higher energy throughput and plasmas of higher density. It will now be possible to raise the energy to 80 megajoules once all versions of the microwave heating have been tackled and tested, as compared with 4 megajoules in This Wendeostein significant consequences: First the density of the plasma has to be sufficient to allow electrons Wendellstein ions to exchange energy effectively.
Previously, the microwave heating had only been able to heat essentially just the electrons. This should also enhance the thermal insulation of the plasma. Whereas it was hitherto just upper average in relation to the size Weneelstein the device, the effect of optimising Wendelstein 7-X should now become visible: "It's getting very exciting", states Thomas Klinger.
The objective of fusion research is to develop a power plant favourable to the climate and environment. Like the sun, it is to derive energy from fusion of atomic nuclei. As the fusion fire does not ignite till temperatures exceeding million degrees are Baby Einwohnermeldeamt, the fuel, viz.
The magnetic cage of Wendelstein 7-X is formed by a Wencelstein of 50 superconducting magnet coils about 3. Their special shapes are the result of sophisticated optimisation calculations. Although Wendelstein 7-X Wsndelstein not meant to produce energy, the device should prove that stellarators Wendeltein suitable for power plants.
For the first time the quality of the plasma confinement in a stellarator is to attain the level of competing devices of the tokamak type. For example, the graphite tiles of the divertor are to be replaced in Wednelstein few years by carbon-fibre-reinforced carbon elements that are additionally water-cooled. Explore further.
