Princeton Plasma Physics Laboratory has developed an improved model for forecasting the crucial balance of pressure at the edge of a fusion plasma. A key requirement for future facilities that aim to capture and control on Earth the fusion energy that drives the sun and stars is accurate predictions of the pressure of the plasma. […]

The Department of Energy’s Princeton Plasma Physics Laboratory has published an article describing a simulation of the mechanism that eliminates sawtooth instabilities in fusion plasmas. Sawtooth swings, the up-and-down ripples found in everything from stock prices on Wall Street to ocean waves, occur periodically in the temperature and density of the plasma that fuels fusion […]
