Engineers use AI to wrangle fusion power for the grid

In the blink of an eye, the unruly, superheated plasma that drives a fusion reaction can lose its stability and escape the strong magnetic fields confining it within the donut-shaped fusion reactor. These getaways frequently ...

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 ...
