First results from the paleomagnetic study of Cumbre Vieja

Josep M. Parés, coordinator of the Geochronology and Geology Program at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has led the first study of the magnetic properties of the lava and ash produced ...

Avoiding chains of magnetic islands may lead to fusion paradise

To create the conditions needed for fusion reactions, tokamak reactors contain a plasma in magnetic fields. These magnetic fields can contain tubular areas called magnetic islands. Plasma particles move extra quickly across ...

Fuel injection helps reduce magnetic island instabilities

Fusion is a non-carbon-based process for energy production, where lighter atoms fuse into heavier ones. Fusion reactors operate by confining a "soup" of charged particles, known as a plasma, within powerful magnetic fields. ...

Scientists discover a process that stabilizes fusion plasmas

Scientists seeking to bring the fusion reaction that powers the sun and stars to Earth must keep the superhot plasma free from disruptions. Now researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics ...

Higher plasma densities, more efficient tokamaks

When the density of the hot, ionized gas (known as a plasma) in a tokamak exceeds a certain limit, it usually leads to a rapid loss of heat and plasma currents. The currents are required to confine the plasma. Such events ...
