A novel path to fusion ignition: Heat first, then add fuel

For more than 70 years, fusion energy researchers have used a particular equation to judge whether a plasma would stay hot and dense enough—for long enough—to reach a point where it could sustain itself without any more external ...

How fusion reactions can survive flaws—up to a point

Researchers at Lawrence Livermore National Laboratory (LLNL) have found that implosions designed for inertial fusion energy (IFE) can tolerate significant imperfections before performance abruptly declines, a finding that ...

Connecting the power of the stars to geometry

In the world of fusion energy, scientists and engineers study the fourth state of matter known as plasma in an effort to design and build a new type of power plant. Relying on the heat produced by two small atoms smashing ...

Tiny vortices discovered on the sun's surface

Researchers from the U.S. National Science Foundation National Solar Observatory (NSF NSO), the Max Planck Institute for Solar System Research (MPS) in Germany, and the High Altitude Observatory (HAO) in the U.S. have made ...

Pushing the boundaries of ultracold neutral plasmas

Using a combination of laser cooling techniques and strong magnetic fields, researchers at Colorado State University have for the first time created an ultracold neutral plasma with electrons cooled to temperatures measured ...

Actively reducing noise by ionizing air

Did you know that wires can be used to ionize air to make a loudspeaker? Simply put, it's possible to generate sound by creating an electric field in a set of parallel wires, aka a plasma transducer, strong enough to ionize ...

Demystifying vortex rings in nuclear fusion and supernovae

Better understanding the formation of swirling, ring-shaped disturbances—known as vortex rings—could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source.

New discovery points the way to more compact fusion power plants

A magnetic cage keeps the more than 100 million degree Celsius hot plasmas in nuclear fusion devices at a distance from the vessel wall so that they do not melt. Now researchers at the Max Planck Institute for Plasma Physics ...
