A major roadblock to producing safe, clean and abundant fusion energy on Earth is the lack of detailed understanding of how the hot, charged plasma gas that fuels fusion reactions behaves at the edge of fusion facilities called “tokamaks.” Recent breakthroughs by researchers at the U.S.
Mike Bonkalski, the Princeton Plasma Physics Laboratory’s (PPPL) new head of Environment, Safety, and Health (ES&H), brings almost 30 years of experience at two national laboratories to the position that oversees health and safety at a crucial time for the Laboratory as it begins several majo
David Graves, an internationally-known chemical engineer, has been named to lead a new research enterprise that will explore plasma applications in nanotechnology for everything from semiconductor manufacturing to the next generation of super-fast quantum computers.
More than 100 PPPL parents and children attended the Princeton Plasma Physics Laboratory’s Take Your Daughters and Sons to Work (at Home) Day on April 23 to watch plasma experiments and find out about science experiments they can do at home. (The experiments are listed below).
More than 125 staff members at the Princeton Plasma Physics Laboratory (PPPL) virtual celebration of Earth Day on April 22 celebrated the 50th Anniversary of Earth Day, which focused attention on the need to reduce pollution and become more sustainable, and recognized PPPL staff who ar
A key challenge to capturing and controlling fusion energy on Earth is maintaining the stability of plasma — the electrically charged gas that fuels fusion reactions — and keeping it millions of degrees hot to launch and maintain fusion reactions.
Ian Ochs, a graduate student in the Program in Plasma Physics, has won a Porter Ogden Jacobus Fellowship, the most prestigious of the honorific fellowships that the University awards annually for academic excellence.
A key issue for scientists seeking to bring the fusion that powers the sun and stars to Earth is forecasting the performance of the volatile plasma that fuels fusion reactions. Making such predictions calls for considerable costly time on the world’s fastest supercomputers.
Carefully manipulating the outer skin of plasma can create cascades of effects that help create the stability needed to sustain fusion reactions, scientists have found. The research, led by physicist Dylan Brennan of the U.S.
Mercury, the planet nearest the sun, shares with Earth the distinction of being one of the two mountainous planets in the solar system with a global magnetic field that shields it from cosmic rays and the solar wind.
Scientists seeking to bring the fusion that powers the sun and stars to Earth must deal with sawtooth instabilities — up-and-down swings in the central pressure and temperature of the plasma that fuels fusion reactions, similar to the serrated blades of a saw. If these swings are large enough, t
Creating and controlling on Earth the fusion energy that powers the sun and stars is a key goal of scientists around the world. Production of this safe, clean and limitless energy could generate electricity for all humanity, and the possibility is growing closer to reality.

In an abundance of caution around the coronavirus pandemic, and in light of presumptive cases in the Princeton area, the Princeton Plasma Physics Laboratory is curtailing operations and sending employees home to work effective 5 p.m.
Women contribute to the Princeton Plasma Physics Laboratory’s mission in every department, whether it’s in Engineering, Research, or Operations, Click here to view o
Permanent magnets akin to those used on refrigerators could speed the development of fusion energy – the same energy produced by the sun and stars.
Researchers have found that injecting pellets of hydrogen ice rather than puffing hydrogen gas improves fusion performanceat the DIII-D National Fusion Facility, which General Atomics operates for the U.S. Department of Energy (DOE).
The New Jersey Regional Science Bowl final contests Feb. 21 and 22 at the Princeton Plasma Physics Laboratory were nail-biters to the end with Princeton Charter School and Ridge High School, of Basking Ridge, New Jersey, battling it out to win the right to compete in the U.S.

A key hurdle facing fusion devices called stellarators — twisty facilities that seek to harness on Earth the fusion reactions that power the sun and stars — has been their limited ability to maintain the heat and performance of the plasma that fuels those reactions.
Magnetic field lines that wrap around the Earth protect our planet from cosmic rays. Researchers at the U.S.
Like most teams preparing for a big competition, the 16 middle school teams and 32 high school teams coming to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) on Feb.
What a decade it’s been for fusion and plasma physics research at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL)!
A long-standing puzzle in space science is what triggers fast magnetic reconnection, an explosive process that unfolds throughout the universe more rapidly than theory says it should.
What does the future hold for the development of fusion energy as a safe, clean and virtually limitless source of power to generate electricity? To find out, the Andlinger Center for Energy and Environment at Princeton University spoke with Steve Cowley, director of the U.S.
The American Physical Society (APS) has recognized a summer intern at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) for producing an outstanding research poster at the world-wide APS Division of Plasma Physics (DPP) gathering last October.
Turbulence — the unruly swirling of fluid and air that mixes coffee and cream and can rattle airplanes in flight — causes heat loss that weakens efforts to reproduce on Earth the fusion that powers the sun and stars.
Researchers led by C.S. Chang of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have been awarded major supercomputer time to address key issues for ITER, the international experiment under construction in France to demonstrate the practicality of fusion energy.
Scientists often make progress by coming up with new ways to look at old problems. That has happened at the U.S.
Arms control robots, a new national facility, and accelerating the drive to bring the fusion energy that powers the sun and stars to Earth. These far-reaching achievements at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) made 2019 another remarkable year.
