Spherical tokamak as model for next steps in fusion energy

Among the top puzzles in the development of fusion energy is the best shape for the magnetic facility—or "bottle"—that will provide the next steps in the development of fusion reactors. Leading candidates include spherical ...

Chinese fusion test reportedly reaches new milestone

Fusion power has long been considered to be the holy grail of alternative energy. Clean, abundant power, created through a self-sustaining process where atomic nuclei are fused at extremely high temperatures. Achieving this ...

Scientific vandalism helps ITER

Scientists at JET, the world's largest fusion energy research facility, have been deliberately melting parts of their own machine as they test materials for the fusion reactors of the future. These apparent acts of scientific ...

Understanding the turbulence in plasmas

A longstanding joke holds that practical fusion power is about 20 years away—and always will be. One simple phenomenon explains why practical, self-sustaining fusion reactions have proved difficult to achieve: Turbulence ...

Disruption mitigation researchers investigate design options

ITER, the world's first reactor-scale fusion machine, will have a plasma volume more than 10 times that of the next largest tokamak, JET. Plasma disruptions that can occur in a tokamak when the plasma becomes unstable can ...

New probe to uncover mechanisms key to fusion reactor walls

(PhysOrg.com) -- A new tool developed by nuclear engineers at Purdue University will be hitched to an experimental fusion reactor at Princeton University to learn precisely what happens when extremely hot plasmas touch and ...
