The National Spherical Torus Experiment (NSTX), which is undergoing a $94 million upgrade that will make it the most powerful experimental fusion facility, or tokamak, of its type in the world when work is completed in 2015. Experiments will test the ability of the upgraded spherical facility to maintain a high-performance plasma under conditions of extreme heat and power. Results could strongly influence the design of future fusion reactors.

Chirping is welcome in birds but not in fusion devices – scientists show that weak turbulence makes chirping more likely

Birds do it and so do doughnut-shaped fusion facilities called “tokamaks.” But tokamak chirping— a rapidly changing frequency wave that can be far above what the human ear can detect — is hardly welcome to researchers who seek to bring the fusion that powers the sun and stars to Earth.  Such chirping signals a loss of heat that can slow fusion reactions, a loss that has long puzzled scientists.

The mysteries of plasma and solar eruptions earn PPPL graduate an astrophysics prize

Clayton Myers, a 2015 graduate of the Program in Plasma Physics in the Princeton Department of Astrophysical Sciences who did his research at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has won the 2018 Dissertation Prize awarded by the Laboratory Astrophysics Division (LAD) of the American Astronomical Society (AAS). Myers, now a physicist at Sandia National Laboratory, received the award for his work on the Magnetic Reconnection Experiment (MRX) at PPPL.

Ten stories in 2017 you may have missed, plus a bonus

Throughout 2017 researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have produced new insights into the science of fusion energy that powers the sun and stars and the physics of plasma, the hot, charged state of matter that consists of electrons and atomic nuclei, or ions, and makes up 99 percent of the visible universe. The research advances the development of fusion as a safe, clean and plentiful source of power, produced in doughnut-shaped facilities called tokamaks, and explores the diverse aspects and applications of plasma.
