The first helium plasma has been produced in the Wendelstein 7-X fusion device at the Max Planck Institute for Plasma Physics (IPP) in Greifswald, Germany. The most comprehensive sci-tech news coverage on the web. Its goal is to investigate the suitability of such facilities for power production. Wendelstein 7-X is the world’s largest fusion device of the stellarator type. While a tokamak is based on a uniform toroidal shape, a stellarator twists that shape in a figure eight. It should show that stellarators - with discharges lasting 30 minutes - have the ability to operate continuously. No, she was not setting off some new kind of hydrogen bomb. Their special shapes are the result of refined optimisation calculations carried out by the “Stellarator Theory Department”, which spent more than ten years searching for a magnetic cage that is particularly heat insulating. This has been carried out by the Integrated Technical Centre (ITZ) and the Components in the Plasma Vessel working group at IPP, in cooperation with industrial companies. The coolant is supplied by small steel tubes to ensure that the heat energy is removed. The Wendelstein 7-X stellarator is a machine that looks too odd and complex to be real. Wendelstein 7-X will test an optimised magnetic field for confining the plasma, which will be produced by a system of 50 non-planar and superconducting coils, which is the core piece of the device.
