Oak Ridge's director of fusion energy explains why the global race to build the world’s first fusion plant still depends on ...

The prototype machine with 150 million o C indoors is not a power plant, but it marks the boundary: that is quite hot, far ...

Abstract: Tokamaks are the most promising approach for nuclear fusion on earth. They are toroidal machines where the plasma is heated in a ring-shaped vessel and kept away from the vessel by applied ...

The Wendelstein 7-X (W7-X) is the largest and most advanced stellarator in the world, and on its tenth birthday, it’s clear the experiment has graduated from a bold engineering prototype to a running ...

In experimental tokamaks, plasmas are pulsed, meaning they are created, sustained for a brief period, and then deliberately turned off. When a plasma becomes unstable during its main phase, or when a ...

A longstanding mystery in nuclear fusion research may have been solved, thanks to a new theoretical model that could help scientists resolve why simulations often underestimate the turbulence at the ...

Recent developments in fusion energy modeling, such as a new “nonperturbative guiding center model,” enhance scientists’ ability to simulate plasma behavior in fusion reactors. These improvements ...

ABSTRACT: A new effect has been added to explain the disruption of the Tokamak which involves the creation of a mini black hole by the hot electrons within the plasma of the Tokamak. The problem ...

At the Columbia Plasma Physics Lab, researchers are tackling one of the most pressing challenges in creating clean energy: making nuclear fusion a viable power source. Unlike nuclear fission—the type ...

France’s Commissariat à L'énergie Atomique et aux Energies Alternatives on Tuesday claimed it’s topped China’s recently-established for record maintaining fusion plasma in a tokamak, and therefore ...
