Scientists pursuing magnetically-confined nuclear fusion as a clean energy source grapple with the "core-edge challenge," the ...

In the DIII-D experiments, this shape demonstrated unexpectedly low levels of instability. Researchers were able to achieve ...

Researchers at the University of British Columbia have shown that a small bench-top reactor can enhance nuclear fusion rates ...

The first 'negative triangularity' nuclear reactor has achieved first plasma. What else will it achieve?

Fusion scientists are considering smaller-sized, different-shaped nuclear reactors, or tokamaks, to achieve breakeven and gain.

Reactors use a high-energy state of matter or ionized gas in a plasma form, which still isn’t entirely understood by scientists.

Seeking to improve the tokamak fusion reactor known as ITER, researchers have found a way to stop rogue tungsten atoms from shearing off the walls and messing with the plasma. The finding is ...

The Wendelstein 7-X stellarator in Germany has broken the record for plasma duration in a nuclear fusion reactor. Fusion reactions were sustained at high performance levels for 43 seconds, which ...

General Fusion has been working on its unique approach to producing clean energy for two decades, and it's now got something major to show for it. The company has created plasma in its prototype ...

WEST, a fusion reactor in France, broke a record for tungsten tokamaks with a 6-minute plasma. It's an important step toward clean, limitless energy.
