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.

New model sheds light on key physics of magnetic islands that halt fusion reactions

Magnetic islands, bubble-like structures that form in fusion plasmas, can grow and disrupt the plasmas and damage the doughnut-shaped tokamak facilities that house fusion reactions. Recent research at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has used large-scale computer simulations to produce a new model that could be key to understanding how the islands interact with the surrounding plasma as they grow and lead to disruptions.
