PPPL celebrates 50th Anniversary of Earth Day by recognizing greenest employees

More than 125 staff members at the Princeton Plasma Physics Laboratory (PPPL) virtual celebration of Earth Day on April 22 celebrated the 50^th Anniversary of Earth Day, which focused attention on the need to reduce pollution and become more sustainable, and recognized PPPL staff who are putting sustainable practices into action.

As a national laboratory with the mission of creating a potentially inexhaustible source of energy with fusion energy, the same energy that powers the sun and the stars, PPPL has long had a very strong commitment to the environment

10 Questions for Steven Cowley, New Director of the Princeton Plasma Physics Laboratory

Steven Cowley, a theoretical physicist and international authority on fusion energy, became the seventh Director of the Princeton Plasma Physics Laboratory (PPPL) on July 1 and will be Princeton professor of astrophysical sciences on September 1.

PPPL physicist receives ExxonMobil grant for plasma research

Physicist Egemen Kolemen, who holds positions at Princeton University and the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), is sharing a grant from ExxonMobil to research whether plasma could reduce greenhouse gas emissions associated with oil wells. Plasma is partially ionized gas that has separated into electrons and atomic nuclei, and can be found on Earth as lightning, neon lights, and many other forms. Stars and 99 percent of the visible universe are made of plasma.

How Does Fusion Energy Work?

Fusion is the energy source of the sun and stars.

Major next steps for fusion energy based on the spherical tokamak design

Spherical tokamaks could serve as a model for unlimited carbon-free energy.

Energy Secretary Moniz Launches the Nation’s Newest Fusion Experiment at PPPL

U.S. Department of Energy Secretary Ernest Moniz dedicated the most powerful spherical torus fusion facility in the world on Friday, May 20, 2016. The $94-million upgrade to the National Spherical Torus Experiment (NSTX-U), funded by the DOE Office of Science, is a spherical tokamak fusion device that explores the creation of high-performance plasmas at 100-million degree temperatures many times hotter than the core of the sun.

Top-5 Achievements at the Princeton Plasma Physics Laboratory in 2015

A look at major scientific and engineering advances in research developments during the past year.

PPPL physicists simulate innovative method for starting up tokamaks without using a solenoid

Scientists at 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.

Using powerful computers, physicists uncover mechanism that stabilizes plasma within tokamaks

A team of physicists led by Stephen Jardin of the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has discovered a mechanism that prevents the electrical current flowing through fusion plasma from repeatedly peaking and crashing. This behavior is known as a "sawtooth cycle" and can cause instabilities within the plasma's core. The results have been published online in Physical Review Letters. The research was supported by the DOE Office of Science.
