Inside job: A new technique to cool a fusion reactor

Fusion offers the potential of near limitless energy by heating a gas trapped in a magnetic field to incredibly high temperatures where atoms are so energetic that they fuse together when they collide. But if that hot gas, ...

New method to replicate harsh conditions for materials

Confining a plasma jet can be stress-inducing, especially on the shielding materials. Noting the limits inherent in the test methods currently used for such materials, Professor Patrizio Antici and his colleagues have proposed ...

Researchers take next step toward fusion energy

Fusion is the process that powers the sun, harnessing it on Earth would provide unlimited clean energy. However, researchers say that constructing a fusion power plant has proven to be a daunting task, in no small part because ...

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 ...

Plasma physicist discusses the Wendelstein 7-X stellarator

Researchers from the Max Planck Institute for Plasma Physics (IPP) produced the first helium plasma in the Wendelstein 7-X stellarator last December. Since then, they have cleaned the plasma vessel with many more helium discharges. ...

Fusion reactors 'economically viable' say experts

Fusion reactors could become an economically viable means of generating electricity within a few decades, and policy makers should start planning to build them as a replacement for conventional nuclear power stations, according ...
