Getting a significant energy return from tokamak-based nuclear fusion reactors depends for a large part on plasma density, but increasing said density is tricky, as beyond a certain point the ...

China's EAST reactor achieved plasma densities 1.65x beyond theoretical limits, solving fusion's 70-year puzzle and bringing ...

China’s Experimental Advanced Superconducting Tokamak, better known as the country’s “artificial sun,” has just done something fusion physicists long treated as impossible. By pushing plasma to ...

The governments of the United States and the United Kingdom have joined hands with Tokamak Energy to advance the nuclear fusion science and technology needed for a future pilot plant. The new ...

Ohysicists at the University of Wisconsin–Madison produced a tokamak plasma that is stable at 10 times the [old] Greenwald limit. The findings may have implications for tokamak fusion reactors, though ...

China’s latest experiments with its so‑called “artificial sun” have pushed nuclear fusion into territory many physicists long ...

Experiments at China's Experimental Advanced Superconducting Tokamak have confirmed the existence of "a density-free region" of the tokamak, finding a method to break through the density limit and ...

Harnessing energy from plasma requires a precise understanding of its behavior during fusion to keep it hot, dense and stable. A new theoretical model about a plasma’s edge, which can become unstable ...

First tokamak plasma at the SMall Aspect Ratio Tokamak – SMART – recorded with a fast-framing camera in the visible spectral range. In a pioneering approach to achieve fusion energy, the SMART device ...

At 4 a.m., while most of New Jersey slept, a Princeton Plasma Physics Laboratory (PPPL) physicist sat at his computer connected to a control room 3,500 miles away in Oxford, England. Years of ...
