Hot stuff: Lab hits milestone on long road to fusion power

With 192 lasers and temperatures more than three times hotter than the center of the sun, scientists hit—at least for a fraction of a second—a key milestone on the long road toward nearly pollution-free fusion energy.

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 ...

Visualizing the microscopic world of fast ions in fusion devices

The U.S. scientific community is currently conceptualizing the first nuclear fusion power plants, which will revolutionize energy production. Like the sun and stars, a fusion power plant will produce energy by fusing light ...

Unveiling the steady progress toward fusion energy gain

The march towards fusion energy gain, required for commercial fusion energy, is not always visible. Progress occurs in fits and starts through experiments in national laboratories, universities, and more recently at private ...

A major challenge to harvesting fusion energy on Earth

A key challenge for scientists striving to produce on Earth the fusion energy that powers the sun and stars is preventing what are called runaway electrons, particles unleashed in disrupted fusion experiments that can bore ...
