From helping the nation’s power grid to advancing the creation of “a star in a jar” for a virtually endless supply of electric power, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed insights and discoveries over the past year that advance understanding of the universe and the prospect for safe, clean, and abundant energy.

On Alcatraz Island, students from Princeton University peered across the San Francisco skyline from a solar rooftop. Their visit to the historic prison’s electricity microgrid was one stop on a spring break trip to see emerging energy technologies, part of a new course on energy innovation and entrepreneurship.
“Before this class I didn't even know what the energy sector looked like,” said Diego Fierros, a senior studying mechanical and aerospace engineering. “It was a giant engineering conglomerate.”

A key obstacle to controlling on Earth the fusion that powers the sun and stars is leakage of energy and particles from plasma, the hot, charged state of matter composed of free electrons and atomic nuclei that fuels fusion reactions. At the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), physicists have been focusing on validating computer simulations that forecast energy losses caused by turbulent transport during fusion experiments.

High-energy ion beams — laser-like beams of atomic particles fired through accelerators — have applications that range from inertial confinement fusion to the production of superhot extreme states of matter that are thought to exist in the core of giant planets like Jupiter and that researchers are eager to study. These positively charged ion beams must be neutralized by negatively charged electrons to keep them sharply focused. However, researchers have found many obstacles to the neutralization process.

Institutions ranging from NASA to the Korean Physical Society have recently bestowed national and international honors on four scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The awards recognize a veteran and three early career physicists for their path-setting achievements in fusion and plasma science research. The honorees and their notable contributions:
Rajesh Maingi named Fellow of the American Nuclear Society

Machine learning (ML), a form of artificial intelligence that recognizes faces, understands language and navigates self-driving cars, can help bring to Earth the clean fusion energy that lights the sun and stars. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) are using ML to create a model for rapid control of plasma — the state of matter composed of free electrons and atomic nuclei, or ions — that fuels fusion reactions.

Scientists have created a novel method for measuring the stability of a soup of ultra-hot and electrically charged atomic particles, or plasma, in fusion facilities called “tokamaks.” Involving an innovative use of a mathematical tool, the method might lead to a technique for stabilizing plasma and making fusion reactions more efficient.

Artificial intelligence (AI), a branch of computer science that is transforming scientific inquiry and industry, could now speed the development of safe, clean and virtually limitless fusion energy for generating electricity. A major step in this direction is under way at the U.S.

Scientists seeking to capture and control on Earth fusion energy, the process that powers the sun and stars, face the risk of disruptions — sudden events that can halt fusion reactions and damage facilities called tokamaks that house them. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), and the University of Washington have developed a novel prototype for rapidly controlling disruptions before they can take full effect.
