Delivered to the Committee on Science, Space and Technology Subcommittee on Energy For the hearing on April 20, 2016
Imène Goumiri, a Princeton University graduate student, has worked with physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) to simulate a method for limiting instabilities that reduce the performance of fusion plasmas.
Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have helped design and test a component that could improve the performance of doughnut-shaped fusion facilities known as tokamaks.
Some 575 seventh- to tenth-grade girls from throughout New Jersey, as well as Pennsylvania and Maryland, found fun and inspiration doing myriad hands-on activities and meeting female scientists at The Princeton Plasma Physics Laboratory’s 15th annual Young Women’s Conference in Science
The world of fusion energy is a world of extremes. For instance, the center of the ultrahot plasma contained within the walls of doughnut-shaped fusion machines known as tokamaks can reach temperatures well above the 15 million degrees Celsius core of the sun.
Physicists have long regarded plasma turbulence as unruly behavior that can limit the performance of fusion experiments. But new findings by researchers associated with the U.S.
Big Bang neutrinos are believed to be everywhere in the universe but have never been seen.
The path to creating sustainable fusion energy as a clean, abundant and affordable source of electric energy has been filled with “aha moments” that have led to a point in history when the international fusion experiment, ITER, is poised to produce more fusion energy than it uses when it is compl
Fifty seventh- and eighth-graders from John Witherspoon Middle School in Princeton came to PPPL for a half day on March 4 to become scientists – doing a variety of hands-on science activities, from building a motor to sampling ice cream frozen with liquid nitrogen in a cryogenics demonstration, t
The electric current that powers fusion experiments requires superb control. Without it, the magnetic coils the current drives cannot contain and shape the plasma that fuels experiments in doughnut-shaped tokamaks correctly.
Charles Gentile, an engineer at PPPL, and fellow inventors George Ascione and Adam Cohen won third prize at Princeton University Keller Center’s 11th Annual Innovation Forum on Feb.
When you think of a physicist, what comes to mind? Perhaps a figure in a white lab coat tinkering with complex machinery. Or maybe a wild-haired theoretician scribbling equations on a chalkboard.
The West Windsor-Plainsboro South High School Science Bowl team is going to Washington, DC, for the second consecutive year after emerging undefeated in 12 rounds of challenging science and mathematics questions at the New Jersey Regional Science Bowl at the U.S.
The life of a subatomic particle can be hectic. The charged nuclei and electrons that zip around the vacuum vessels of doughnut-shaped fusion machines known as tokamaks are always in motion.
- It’s the fourth state of matter: Solid, liquid, gas, and plasma. Plasma is a super-heated gas, so hot that its electrons get out of the atom’s orbit and roam free.
As the most powerful spherical tokamak in the world, the National Spherical Torus Experiment-Upgrade (NSTX-U) at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) produces magnetic forces that are far greater than what its predecessor could generate.
The announcement Feb. 11 of the detection of gravitational waves, predicted by Albert Einstein some 100 years ago, created a surge of excitement among physicists worldwide, including many with ties to Princeton University.
David McComas, an executive leader in managing various complex technical projects and programs, has been named vice president for the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL).
Princeton Plasma Physics Laboratory (PPPL) physicists collaborating on the Wendelstein 7-X (W 7-X) stellarator fusion energy device in Greifswald, Germany, were on hand for the Feb.
The world’s nuclear enrichment programs should be under international control to prevent the development of nuclear weapons after the new arms deal with Iran expires in 10 to 15 years, said Frank von Hippel, a senior Princeton University research physicist and a former security advisor during the
Q: What is fusion and how can it produce energy?
Shannon Greco, a science education program leader at PPPL, has been named one of the YWCA Princeton’s “women of excellence” for her work with young women and disadvantaged youth, including her help in starting two all-girls robotics teams for the YWCA Princeton.
The U.S Department of Energy (DOE) has awarded a total of 80 million processor hours on the fastest supercomputer in the nation to an astrophysical project based at the DOE’s Princeton Plasma Physics Laboratory (PPPL).
- It’s natural. In fact, it’s abundant throughout the universe. Stars – and there are billions and billions of them – produce energy by fusion of light atoms.
- It’s safe. There are no dangerous byproducts.
The same process that determines why certain bees become queen bees while others with the exact same DNA become worker bees also plays a role in how doughnuts eaten by a pregnant woman may influence whether her child becomes obese.
When astronomer Isaac Roberts showed a photograph of the Andromeda Nebula to the Royal Astronomical Society, it caused a huge sensation. “There were audible gasps in the audience,” astronomer Alan Hirshfeld told the audience at the first Ronald E. Hatcher Science on Saturday lecture at the U.S.
From launching the most powerful spherical tokamak on Earth to discovering a mechanism that halts solar eruptions, scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory advanced the boundaries of clean energy and plasma science research in 2015.
Engineers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have finished designing a novel component for the Wendelstein 7-X (W7-X) stellarator, which recently opened at the Max Planck Institute of Plasma Physics (IPP) in Griefswald, Germany.
Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have produced self-consistent computer simulations that capture the evolution of an electric current inside fusion plasma without using a central electromagnet, or solenoid.
