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.

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.

PPPL honors Grierson and Greenough for distinguished research and engineering achievements

A breakthrough in the development of fusion diagnostics and the creative use of radio frequency waves to heat the plasma that fuels fusion reactions earned the 2017 outstanding research and engineering awards from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). Physicist Brian Grierson and engineer Nevell Greenough received the honors from PPPL Interim Director Richard Hawryluk at a ceremony November 7 for their exceptional achievements.

PPPL takes detailed look at 2-D structure of turbulence in tokamaks

A key hurdle for fusion researchers is understanding turbulence, the ripples and eddies that can cause the superhot plasma that fuels fusion reactions to leak heat and particles and keep fusion from taking place. Comprehending and reducing turbulence will facilitate the development of fusion as a safe, clean and abundant source of energy for generating electricity from power plants around the world.

PPPL has a new interim director and is moving ahead with construction of prototype magnets

Rich Hawryluk has been appointed interim director of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) while an international search for a permanent director moves forward, Princeton University Vice President for PPPL David McComas announced recently. Hawryluk, who has been heading the NSTX-U Recovery Planning Project, is an internationally-known physicist and a former deputy director of PPPL. 

Discovered: A quick and easy way to shut down instabilities in fusion devices

Scientists have discovered a remarkably simple way to suppress a common instability that can halt fusion reactions and damage the walls of reactors built to create a “star in a jar.” The findings, published in June in the journal Physical Review Letters, stem from experiments performed on the National Spherical Torus Experiment-Upgrade (NSTX-U), at the Department of Energy’s Princeton Plasma Physics Laboratory (PPPL).
