New insights could help tame speedy ions in fusion plasmas

To create a practical fusion energy reactor, researchers need to control particles known as fast ions. These speedy ions, which are electrically charged hydrogen atoms, provide much of the self-heating ability of the reactor ...

Fuel injection helps reduce magnetic island instabilities

Fusion is a non-carbon-based process for energy production, where lighter atoms fuse into heavier ones. Fusion reactors operate by confining a "soup" of charged particles, known as a plasma, within powerful magnetic fields. ...

China's quest for clean, limitless energy heats up

A ground-breaking fusion reactor built by Chinese scientists is underscoring Beijing's determination to be at the core of clean energy technology, as it eyes a fully-functioning plant by 2050.

Taming turbulence: Seeking to make complex simulations a breeze

For scientists wrestling with problems as diverse as containing superhot plasma in a fusion reactor, improving the accuracy of weather forecasts, or probing the unexplained dynamics of a distant galaxy, turbulence-spawning ...

New world record magnetic field

A group of scientists at the University of Tokyo has recorded the largest magnetic field ever generated indoors—a whopping 1,200 tesla, as measured in the standard units of magnetic field strength.

Pushing the plasma density limit

For decades, researchers have been exploring ways to replicate on Earth the physical process of fusion that occurs naturally in the sun and other stars. Confined by its own strong gravitational field, the sun's burning plasma ...

Diamond – an indispensable material in fusion technology

Fusion power plants promise nearly unlimited climate-friendly energy and scientists worldwide cooperate to reach this goal. A little known aspect of this highly specialized field of research concerns diamond which is in fact ...
