Fusion by strong lasers

Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One of the problems is how to overcome the strong electrical repulsion between atomic nuclei which requires ...

New insights could help tame speedy ions in fusion plasmas

To create a practical fusion energy reactor, researchers need to control particles known as fast ions. These speedy ions, which are electrically charged hydrogen atoms, provide much of the self-heating ability of the reactor ...

Taking a new tangent to control pesky waves in fusion plasmas

Fusion combines light elements in the form of plasma—"the hot, charged state of matter composed of free electrons and atomic nuclei—"to generate massive amounts of energy. One of the ways that scientists help heat the ...

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. ...
