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 ...

Experiments show fusion plasma can stay stable at higher densities by controlling reactor walls, challenging long-standing limits.

For decades, nuclear fusion has been described as the holy grail of clean power, a way to generate vast amounts of energy by mimicking the reactions that light the sun. In the past year, a cluster of ...

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 ...

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 ...

Tokamak plasma systems hold great promise in realising practical nuclear fusion, yet their full potential is constrained by the risk of disruptions – sudden, often catastrophic, losses of plasma ...

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

Scientists have overcome one of the "greatest uncertainties" in the operation of future fusion reactors. In order to shield the fusion plasma from impurities in the reactor walls, which greatly ...

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 plasma ...

The world's largest and most advanced tokamak fusion reactor has gone online as the EU/Japanese 370-tonne JT-60SA reactor was fired up for the first time during an inauguration ceremony in Ibaraki ...

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 ...
