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 ...

Japanese experimental nuclear fusion reactor inaugurated

The world's biggest experimental nuclear fusion reactor in operation was inaugurated in Japan on Friday, a technology in its infancy but billed by some as the answer to humanity's future energy needs.
