A landmark plan for realizing fusion energy and advancing plasma science

Creating and controlling on Earth the fusion energy that powers the sun and stars is a key goal of scientists around the world. Production of this safe, clean and limitless energy could generate electricity for all humanity, and the possibility is growing closer to reality. Now a landmark report released this week by the American Physical Society Division of Plasma Physics Community Planning Process proposes immediate steps for the United States to take to accelerate U.S.

Artificial intelligence helps prevent disruptions in fusion devices

An international team of scientists led by a graduate student at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has demonstrated the use of Artificial Intelligence (AI), the same computing concept that will empower self-driving cars, to predict and avoid disruptions — the sudden release of energy stored in the plasma that fuels fusion reactions  — that can halt the reactions and severely damage fusion facilities.

Risk of disruptions

Feeding fusion: hydrogen ice pellets prove effective for fueling fusion plasmas

Researchers have found that injecting pellets of hydrogen ice rather than puffing hydrogen gas improves fusion performanceat the DIII-D National Fusion Facility, which General Atomics operates for the U.S. Department of Energy (DOE). The studies by physicists based at DOE’s Princeton Plasma Physics Laboratory (PPPL) and Oak Ridge National Laboratory (ORNL) compared the two methods, looking ahead to the fueling that will be used in ITER, the international fusion experiment under construction in France.

New twist in artificial intelligence could enhance the prediction of fusion disruptions

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have used Artificial Intelligence (AI) to create an innovative technique to improve the prediction of disruptions in fusion energy devices — a grand challenge in the effort to capture on Earth the fusion reactions that power the sun and stars.

The outlook for harnessing on Earth the fusion that powers the sun and stars

What does the future hold for the development of fusion energy as a safe, clean and virtually limitless source of power to generate electricity? To find out, the Andlinger Center for Energy and Environment at Princeton University spoke with Steve Cowley, director of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and Princeton University professor of astrophysical sciences, and Egemen Kolemen, a PPPL physicist and assistant professor of mechanical and aerospace engineering and the Andlinger Center.
