A review paper examines the 6-decade history of neutral particle analysis (NPA), a vital diagnostic tool used in magnetic plasma confinement devices such as tokamaks that will house the nuclear fusion process and generate the clean energy of the future. As the world’s energy demands grow, so too does growing concern over the environmental impact […]

A Princeton Plasma Physics Laboratory new computer simulation forecasts a surprisingly optimistic heat load for future fusion facilities designed to harvest on Earth the fusion energy that powers the sun and stars to generate electricity. Efforts to duplicate the fusion reactions on Earth that power the sun and stars for unlimited energy must contend with […]

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 […]
