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 ...

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. ...

Light my fire: How to start up fusion devices every time

How do you start a fusion reaction, the process that lights the sun and stars, on Earth? Like lighting a match to start a fire, you first produce plasma, the state of matter composed of free electrons and atomic nuclei that ...

Improving the magnetic bottle that controls fusion power on Earth

Scientists who use magnetic fields to bottle up and control on Earth the fusion reactions that power the sun and stars must correct any errors in the shape of the fields that contain the reactions. Such errors produce deviations ...
