More than 100 scientists from the U.S. Department of Energy’s (DOE) Princeton Plasma Laboratory (PPPL) joined nearly 2,000 others from around the world in San Jose, California, to discuss the latest findings in plasma science and fusion research. PPPL physicists contributed to papers, talks and presentations ranging from astrophysical plasmas to magnetic fusion energy during the 58th annual meeting of the American Physical Society (APS) Division of Plasma Physics.
PPPL collaborates in fusion experiments conducted by research institutions around the world. Such collaborations include supplying diagnostic equipment to ITER, a joint venture of the European Union, the United States and five other countries that is under construction in the south of France to demonstrate the feasibility of fusion power.
Fusion researcher Robert Goldston, a Princeton University professor of astrophysical sciences and former director of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), received the 2015 Nuclear Fusion Award for the most outstanding paper to appear in the journal Nuclear Fusion during 2012. Presenting the award was Yukiya Amano, director general of the International Atomic Energy Agency (IAEA), during the IAEA’s 2016 Nuclear Fusion Energy Conference in Kyoto, Japan.

Steven Sabbagh, a senior research scientist at Columbia University on long-term assignment to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), has been named lead principal investigator for a multi-institutional project on the Korea Superconducting Tokamak Advanced Research (KSTAR) facility. The three-year, $3.3 million collaboration will study methods of predicting and avoiding disruptions on KSTAR, a long-pulse tokamak that produces plasmas that can last from 30 seconds to a design value of more than five minutes.
Spherical tokamaks could serve as a model for unlimited carbon-free energy.
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. Called a "liquid lithium limiter," the device has circulated the protective liquid metal within the walls of China's Experimental Advanced Superconducting Tokamak (EAST) and kept the plasma from cooling down and halting fusion reactions. The journal Nuclear Fusion published results of the experiment in March 2016. The research was supported by the DOE Office of Science.

A system of antennas similar to those that astrophysicists use to study radio emissions from stars and galaxies will help shed light on fusion experiments at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL).
Schweickhard “Schwick” von Goeler, an award-winning physicist at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) for more than 35 years and the inventor of numerous X-ray diagnostics used in fusion experiments worldwide, died of leukemia on Dec. 6 in Springfield, Massachusetts. He was 84.
