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

France’s Commissariat à L'énergie Atomique et aux Energies Alternatives on Tuesday claimed it’s topped China’s recently-established for record maintaining fusion plasma in a tokamak, and therefore ...

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 another ...

Here’s what you’ll learn when you read this story: In the race for clean energy, no technology is quite as promising as nuclear fusion, but the road toward energy freedom is filled with barriers that ...

A research team has clarified the mechanism behind the generation of runaway electrons during the startup phase of a tokamak fusion reactor. The paper, "Binary Nature of Collisions Facilitates Runaway ...

Researchers have made a leap forward in the pursuit of clean, endless energy. A team at General Atomics, a U.S. Department of Energy-backed facility, has unveiled a key advance in nuclear fusion, the ...

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 ...

Here’s what you’ll learn when you read this story: The plasma density barrier is a mathematical limit to the density of plasma that can exist in a tokamak before destabilizing. A new study led by a ...
