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 ...

Understanding how lasers can rapidly magnetize fusion plasmas

The mechanism that can cause a rapidly expanding plasma—the superhot state of matter harnessed in fusion energy systems—to spontaneously generate its own magnetic fields was identified through a new set of simulations. This ...

Team develops modulator for compact photonic integrated circuits

Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device footprint. The development ...

A new route for plasma-based particle accelerators

Plasma, the fourth state of matter, consists of a gas in which electrons are no longer bound to atoms, which allows electricity to flow freely. When beams of particles moving close to the speed of light travel through plasma, ...
