PPPL’s dynamic diagnostic duo
How two physicists revolutionized a key tool in the worldwide quest to harness fusion energy.
ITER
ITER is a large international fusion experiment aimed at demonstrating the scientific and technological feasibility of fusion energy.
ITER (Latin for "the way") will play a critical role advancing the worldwide availability of energy from fusion — the power source of the sun and the stars.
To produce practical amounts of fusion power on earth, heavy forms of hydrogen are joined together at high temperature with an accompanying production of heat energy. The fuel must be held at a temperature of over 100 million degrees Celsius. At these high temperatures, the electrons are detached from the nuclei of the atoms, in a state of matter called plasma.
PPPL physicist Brian Grierson wins DOE Early Career Research Program grant
Physicist Brian Grierson of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has won a highly competitive Early Career Research Program award sponsored by the DOE’s Office of Science. The five-year grant will total some $2.5 million and fund exploration of the mechanisms that govern the formation and maintenance of the hot edge of fusion plasmas — the electrically charged gas that results in fusion reactions in facilities called tokamaks. The work will be carried out on the DIII-D National Fusion Facility in San Diego.
Plasma Turbulence Simulations Reveal Promising Insight for Fusion Energy
With the potential to provide clean, safe, and abundant energy, nuclear fusion has been called the “holy grail” of energy production. But harnessing energy from fusion, the process that powers the sun, has proven to be an extremely difficult challenge.
Scientists have been working to accomplish efficient, self-sustaining fusion reactions for decades, and significant research and development efforts continue in several countries today.
PPPL extends system for suppressing instabilities to long-pulse experiments on KSTAR
PPPL collaborations have been instrumental in developing a system to suppress instabilities that could degrade the performance of a fusion plasma. PPPL has built and installed such a system on the DIII-D tokamak that General Atomics operates for the U.S. Department of Energy in San Diego and on the Korea Superconducting Tokamak Advanced Research (KSTAR) facility in South Korea — and now is revising the KSTAR design to operate during extended plasma experiments.
Two PPPL-led teams win increased supercomputing time to study conditions inside fusion plasmas
Researchers led by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have won highly competitive allocations of time on two of the world’s fastest supercomputers. The increased awards are designed to advance the development of nuclear fusion as a clean and abundant source of energy for generating electricity.

New imaging technique provides improved insight into controlling the plasma in fusion experiments
A key issue for the development of fusion energy to generate electricity is the ability to confine the superhot, charged plasma gas that fuels fusion reactions in magnetic devices called tokamaks. This gas is subject to instabilities that cause it to leak from the magnetic fields and halt fusion reactions.

Celebrating the 20th anniversary of the tritium shot heard around the world
PPPL's historic experiment made global headlines and marked a milestone in the development of fusion energy
Multinational achievement: PPPL collaborates on record fusion plasma in tokamak in China
A multinational team led by Chinese researchers in collaboration with U.S. and European partners has successfully demonstrated a novel technique for suppressing instabilities that can cut short the life of controlled fusion reactions. The team, headed by researchers at the Institute of Plasma Physics in the Chinese Academy of Sciences (ASIPP), combined the new technique with a method that the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has developed for protecting the walls that surround the hot, charged plasma gas that fuels fusion reactions.
