The study of plasma, a partially-ionized gas that is electrically conductive and able to be confined within a magnetic field, and how it releases energy.

No more zigzags: Scientists uncover mechanism that stabilizes fusion plasmas

Sawtooth swings — 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 reactions in doughnut-shaped facilities called tokamaks. These swings can sometimes combine with other instabilities in the plasma to produce a perfect storm that halts the reactions. However, some plasmas are free of sawtooth gyrations thanks to a mechanism that has long puzzled physicists.

Seth Davidovits wins 2018 Marshall N. Rosenbluth dissertation award

Seth Davidovits, a 2017 graduate of the Program in Plasma Physics in the Princeton University Department of Astrophysical Sciences, has won the 2018 Marshall N. Rosenbluth Outstanding Doctoral Thesis Award presented by the American Physical Society (APS). The award, named for distinguished plasma physicist Marshall Rosenbluth, whose career included 13 years at the U.S.

PPPL diagnostic is key to world record of German fusion experiment

When Germany’s Wendelstein 7-X (W7-X) fusion facility set a world record for stellarators recently, a finely tuned instrument built and delivered by the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) proved the achievement. The record strongly suggests that the design of the stellarator can be developed to capture on Earth the fusion that drives the sun and stars, creating “a star in a jar” to generate a virtually unlimited supply of electric energy.

Advances in plasma and fusion science are described in Quest, PPPL’s research magazine

From analyzing solar flares to pursuing “a star in a jar” to produce virtually limitless 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 for all humankind.

PPPL physicists aim to unlock mysteries of fusion with Early Career Research awards

Physicists Dr. Nate Ferraro and Dr. Sam Lazerson of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have each won 2018 Early Career Research Program awards sponsored by the DOE Office of Science. The two five-year awards will fund PPPL research that could lead to development of the best designs for doughnut-shaped tokamaks and twisty stellarators — the main magnetic-bottles employed worldwide in the effort to produce virtually inexhaustible fusion power on Earth using the reactions that drive the sun and stars.
