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 ...

New design improves water decontamination via plasma jet

Plasma is an ionized gas—that is, a gas containing electrons, ions, atoms, molecules, radicals, and photons. It is often called the fourth state of matter, and surprisingly, it permeates everything. Plasmas, which are artificially ...

Researchers visualize energetic ion flow in fusion devices

In a burning plasma, maintaining confinement of fusion-produced energetic ions is essential to producing energy. These fusion plasmas host a wide array of electromagnetic waves that can push energetic ions out of the plasma.

Process for the optical analysis of trace gases optimized

Laser-based absorption spectroscopy is an important method for determining the concentration of gas components in a sample. Modern devices are highly specialized for detecting very specific gases, such as trace gases in the ...

Physicist explains X-rays that shouldn't exist in 'cold' plasma

For about 20 years, Caltech Professor of Applied Physics Paul Bellan and his group have been creating magnetically accelerated jets of plasma, an electrically conducting gas composed of ions and electrons, in a vacuum chamber ...
