In this initial demonstration, engineers successfully produced plasma within the engine’s exhaust system. Rather than focusing on full fusion reactions yet, the test validated a ...

The exhaust heat generated by a fusing plasma in a commercial-scale reactor may not be as damaging to the vessel's innards as once thought, according to new research about escaping plasma particles.

Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

This still image from a new simulation shows how plasma from the pedestal region is connected through the supposedly last confinement surface into the divertor plasma region. The long and thin lobes ...

Fashioned from the same element found in sand and covered by intricate patterns, microchips power smartphones, augment appliances and aid the operation of cars and airplanes. Now, scientists are ...

In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons—elementary particles that briefly glommed together in countless ...

Fusion power represents a potentially powerful long-term addition to clean energy systems. The technology seeks to replicate the process that powers the sun: fusing light atomic nuclei (typically ...

Plasma happens when gas gets heated to a very high temperature and the atoms lose their electrons. Find out more about this state of matter. Science Trek is available to stream on pbs.org and the free ...
