Canadian startup General Fusion has been working on its unique approach to producing clean energy through nuclear fusion for two decades, and it's now got something major to show for it. The company ...

Designing predictable nuclear fusion reactors requires highly accurate computer models, yet existing simulations often ...

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 ...

Researchers were unsure whether alpha particles would aid or hinder fusion. Simulations suggest they help, by dampening ...

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 operating China’s Experimental Advanced Superconducting Tokamak, known as EAST, have sustained plasma at ...

In February, France's WEST nuclear fusion reactor made a big step toward getting clean, star-like energy for everyone. The machine held superheated plasma for 1,337 seconds, or just over 22 minutes.

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 ...

No one has made a fusion reactor capable of generating power, but physicists have a pretty good road map for how to get there. One major milestone is heating fusion fuel up above 10 million degrees ...

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 ...
