France’s WEST tokamak held a fusion plasma at roughly 50 million degrees Celsius for 1,337 seconds, more than 22 minutes, ...

The interiors of fusion reactors can get seriously chaotic. But for obvious reasons—like extreme temperatures and pressures—researchers aren’t typically able to peek directly inside a reactor. Some ...

Nuclear fusion, which operates on the same principle that powers the sun, is expected to become a sustainable energy source for the future. To achieve fusion power generation, it is essential to ...

New simulations from Princeton Plasma Physics Laboratory suggest that deliberately engineering plasma rotation inside tokamak fusion reactors could dramatically reduce the heat loads that destroy ...

Many tokamaks use what is called positive triangularity plasma to produce energy, but past experiments have found that the inverse of this triangularity could be more stable. A new compact tokamak ...

Researchers using China’s “artificial sun” fusion reactor have broken through a long-standing density barrier in fusion plasma. The experiment confirmed that plasma can remain stable even at extreme ...

Researchers working on China’s ‘artificial sun’ have reported breaking a long-accepted threshold that has limited the operation of nuclear fusion reactors for decades. China’s Experimental Advanced ...

The Large Helical Device (LHD) and the heavy ion beam probe (HIBP) system. The inset on the left shows an enlarged view of the section from the negative ion source to the injection side of the tandem ...

China's "artificial sun" reactor has broken its own world record for maintaining super-hot plasma, marking another milestone in the long road towards near-limitless clean energy. The Experimental ...
