The Wendelstein 7-X concept proves its efficiency

One of the most important optimization goals underlying the Wendelstein 7-X fusion device has now been confirmed. An analysis shows: In the optimized magnetic field cage, the energy losses of the plasma are reduced in the desired way. Wendelstein 7-X is intended to prove that the disadvantages of earlier stellarators can be overcome and that stellarator-type devices are suitable for power plants.
