A persistent asymmetry in fusion exhaust has challenged researchers for years. New simulations show that plasma core rotation, working together with cross-field drifts, determines where particles land ...

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.

Immediately after the Big Bang boomed, the Universe was a trillion-degree ' soup ' of unimaginably dense plasma. In a ...

Chinese scientists have unveiled a superconducting linear plasma device designed to test materials for nuclear fusion reactors. The Superconducting Plasma Wall Interaction Linear Device (SWORD) boasts ...

Much of spacecraft engineering is centered on mitigating the risks that come along with that re-entry process, but there’s one particular aspect of it that has remained a challe ...

Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside the sun. But to recreate the process on Earth, we must control ...

Fusion energy promises clean power by mimicking stars. Scientists are focusing on the reactor wall's edge, where plasma meets ...

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 ...
