New simulations from Princeton Plasma Physics Laboratory suggest that deliberately engineering plasma rotation inside tokamak fusion reactors could dramatically reduce the heat loads that destroy ...

Fusion energy promises a future of clean, nearly limitless power, but building reactors that can survive the extreme ...

Researchers at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory have set a new fusion record on the WEST tokamak, sustaining plasma at roughly 50 million degrees Celsius for six ...

A new model for ballooning instabilities in apple-shaped fusion vessels considers the height and width of the plasma's edge. Harnessing energy from plasma requires a precise understanding of its ...

Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), the private company Tokamak Energy and Kyushu University in Japan have proposed a design for a compact, ...
