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.

The U.S. Department of Energy (DOE) has launched an ambitious new program to encourage private-pubic partnerships to speed the development on Earth of the fusion energy that powers the sun and most stars. The DOE’s Princeton Plasma Physics Laboratory (PPPL) and Oak Ridge National Laboratory, home of the US ITER Project Office, will manage the program, with PPPL physicist Ahmed Diallo serving as deputy director and Oak Ridge fusion engineer Dennis Youchison serving as director. 

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.

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:
