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

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 ...

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 ...

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

At the same time, a current of cold electrons travels toward the heated plasma from the opposite direction. When the two meet, the plasma develops filament-shaped instabilities that SLAC’s facilities ...

Helion announced two milestones: hitting a record temperature of 150 million degrees Celsius and being the first private ...

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 ...

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

China is racing forward in its effort to pave the way in fusion energy science, and state-sponsored media reported earlier this week that one of the country’s next-gen reactors is now under ...

New Zealand-based fusion energy startup OpenStar Technologies says it has become the first commercial company in the world to successfully create and confine plasma using a levitated dipole reactor.
