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.

Energy Secretary Rick Perry cheers on fusion energy, science education at PPPL

The Princeton Plasma Physics Laboratory’s (PPPL) mission of doing research to develop fusion as a viable source of energy is vital to the future of the planet, U.S. Energy Secretary Rick Perry said during an Aug. 9 visit. 

“It’s important not just to PPPL, not just to the DOE (Department of Energy) but to the world,” Perry told staff members during an all-hands meeting. “If we’re able to deliver fusion energy to the world, we’re able to change the world forever.” 

Workshop advances plans for coping with disruptions on international ITER facility

The sixth Annual Theory and Simulation of Disruptions Workshop at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) made substantial progress toward planning a system for mitigating disruptions on ITER, the international experiment under construction in France to demonstrate the feasibility of fusion power. Disruptions, the sudden loss of heat in plasma that halts fusion reactions, can seriously damage ITER and other doughnut-shaped fusion facilities called tokamaks, and are among the major challenges facing the international experiment.

Newest supercomputer to help develop fusion energy in international device

Scientists led by Stephen Jardin, principal research physicist and head of the Computational Plasma Physics Group at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), have won 40 million core hours of supercomputer time to simulate plasma disruptions that can halt fusion reactions and damage fusion facilities, so that scientists can learn how to stop them. The PPPL team will apply its findings to ITER, the international tokamak under construction in France to demonstrate the practicality of fusion energy.

No more zigzags: Scientists uncover mechanism that stabilizes fusion plasmas

Sawtooth swings — up-and-down ripples found in everything from stock prices on Wall Street to ocean waves — occur periodically in the temperature and density of the plasma that fuels fusion reactions in doughnut-shaped facilities called tokamaks. These swings can sometimes combine with other instabilities in the plasma to produce a perfect storm that halts the reactions. However, some plasmas are free of sawtooth gyrations thanks to a mechanism that has long puzzled physicists.

Advances in plasma and fusion science are described in Quest, PPPL’s research magazine

From analyzing solar flares to pursuing “a star in a jar” to produce virtually limitless electric power, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed insights and discoveries over the past year that advance understanding of the universe and the prospect for safe, clean, and abundant energy for all humankind.
