Drifting and bouncing particles can help maintain stability in fusion plasmas

A key challenge in fusion research is maintaining the stability of the hot, charged plasma that fuels fusion reactions inside doughnut-shaped facilities called “tokamaks.” Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), have recently found that drifting particles in the plasma, which consists of free electrons and atomic nuclei, can forestall instabilities that reduce the pressure crucial to high-performance fusion reactions inside these facilities.

A battle of the brains between local rivals at N.J. Regional Science Bowl

As the final competitions took place at the Olympics in South Korea, a battle of the brains was taking place at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) on Feb. 23 and 24 where two local teams won the New Jersey Regional Science Bowl and the chance to compete in the national contest in Washington D.C. 

Plasma bubbles help trigger massive magnetic events in outer space

Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered key conditions that give rise to fast magnetic reconnection, the process that triggers solar flares, auroras, and geomagnetic storms that can disrupt signal transmissions and other electrical activities, including cell phone service. The process occurs when the magnetic field lines in plasma, the hot, charged state of matter composed of free electrons and atomic nuclei, break apart and violently reconnect, releasing vast amounts of energy.

Fusion breakthroughs among highlights of the Department of Energy’s research milestones during the past 40 years

The U.S. Department of Energy’s (DOE) Office of Science, the largest U.S. supporter of basic research in the physical sciences, celebrated the 40th anniversary of its founding in 2017.  To mark the 40th anniversary of Office of Science support for the country’s national laboratories and basic research at universities and private industry, the DOE has compiled 40 milestone papers that represent what the Department calls “a cream-of-the crop selection that has changed the face of science.”
