New simulations from Princeton Plasma Physics Laboratory suggest that deliberately engineering plasma rotation inside tokamak fusion reactors could dramatically reduce the heat loads that destroy ...

China breaks a historic barrier in nuclear fusion, bringing the dream of nearly infinite energy closer to reality.

A 0.5-tonne superconducting magnet recently hovered silently inside a 5-meter-wide vacuum chamber, which marked ...

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 ...

The stakes of the “race to fusion” are dramatic. Commercial fusion has the potential to deliver nearly unlimited energy by ...

Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

Type One Energy, which has developed an alternative to the tokamak magnetic confinement systems typically used in nuclear ...

Chinese scientists break a historic barrier and achieve the highest plasma density in a nuclear fusion reactor.

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 ...

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 ...

A fusion reactor dismantled in the UK and reassembled in the Czech Republic celebrated its first plasma late last year. The $32 million device was handed over for a symbolic £1. A fusion reactor ...
