Commonwealth Fusion Systems has begun assembling its SPARC tokamak by placing the first of 18 toroidal-field magnets into the ...

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 ...

Engineers are preparing for high-current trials at ITER’s newly activated Magnet Cold Test Facility, ...

In a pioneering approach to achieve fusion energy, the SMART device has successfully generated its first tokamak plasma. This step brings the international fusion community closer to achieving ...

Earlier this morning, the International Thermonuclear Experimental Reactor (ITER) Organization announced what has long been known: The largest tokamak in the world will be delayed further, prolonging ...

Japan’s JT-60SA fusion reactor project announced first plasma in October of this year to denote the successful upgrades to what is now the world’s largest operational, superconducting tokamak fusion ...

Some believe the future of fusion in the U.S. lies in compact, spherical fusion vessels. A smaller tokamak, it is thought, could offer a more economical fusion option. The trick is squeezing ...

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 ...

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 ...
