Predator and prey: The upper graph shows the predator-prey relationship between the magnetic island and the bootstrap current. The bottom diagrams show the situation in the Large Helical Device when ...

You may not have heard of a Stellarator before, but if all goes well later this month in a small university town in the far northeast of Germany, you will. That’s because the Wendelstein 7-X is ...

New Jersey-based Thea Energy, one of several U.S. companies working to commercialize fusion energy, said the company has ...

On May 22, researchers achieved a major milestone in the pursuit of clean, limitless energy. At the Wendelstein 7-X facility in Germany, scientists set a world record for sustaining a fusion-grade ...

Many moons ago, Ars was introduced to the Wendelstein 7-X stellarator (W7-X), an experimental fusion concept. At the time, W7-X—the world’s largest stellarator—had just completed some warm-up tests ...

In a large complex located at Greifswald in the north-east corner of Germany, sits a new and unusual nuclear fusion reactor awaiting a few final tests before being powered-up for the very first time.

After more than a year of technical preparations and tests, the Wendelstein 7-X stellarator has produced its first helium plasma. After more than a year of technical preparations and tests, the ...

After successful recommissioning in autumn 2022, the Greifswald nuclear fusion experiment has surpassed an important target. In 2023, an energy turnover of 1 gigajoule was targeted. Now the ...

The turbulence code GENE (Gyrokinetic Electromagnetic Numerical Experiment), has proven to be very useful for the theoretical description of turbulence in the plasma of tokamak-type fusion devices.
