Scientist reveals cause of lost magnetism at meteorite site

A University of Alaska Fairbanks scientist has discovered a method for detecting and better defining meteorite impact sites that have long lost their telltale craters. The discovery could further the study of not only Earth's ...

Radio-frequency wave scattering improves fusion simulations

In the quest for fusion energy, understanding how radio-frequency (RF) waves travel (or "propagate") in the turbulent interior of a fusion furnace is crucial to maintaining an efficient, continuously operating power plant. ...

Upgraded code reveals a source of damaging fusion disruptions

Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) and Los Alamos National Laboratory have uncovered a key process behind a major challenge called thermal quenches, the rapid heat loss ...

Neutral particles a drag on disruptive plasma blobs

For decades, scientists have been working to harness clean, renewable fusion energy, which occurs naturally in stars like our sun. Using strong magnetic fields to confine hot plasmas within a donut-shaped device called a ...

Harnessing hot helium ash to drive rotation in fusion reactors

In controlled nuclear fusion, heavy isotopes of hydrogen fuse into helium, releasing a huge amount of energy in the process. A large portion of the energy released by a laboratory fusion reaction goes into hot helium ash ...
