Experiments show fusion plasma can stay stable at higher densities by controlling reactor walls, challenging long-standing limits.

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 ...

In this video, I explore the challenges of nuclear fusion while visiting the JET tokamak fusion reactor at the Culham Science ...

A joint research team from Hefei Institutes of Physical Science of the Chinese Academy of Sciences has successfully developed a continuous cryogenic pellet injection system for tokamak fueling. This ...

Germany's Wendelstein 7-X - the world's largest stellarator-type fusion device - has achieved a world record in a key parameter of fusion physics: the triple product. This value now exceeds previous ...

Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside the sun. But to recreate the process on Earth, we must control ...
