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.
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.
Leading experts from around the world gathered at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) in July to focus on a key issue for the development of fusion energy: Improving ways to predict and mitigate disruptions that can destroy magnetically confined plasmas that are needed for fusion reactions.
Phil Heitzenroeder, who leads the Mechanical Engineering Division at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and whose advice is sought by engineers around the world, has won the 2013 Fusion Technology Award. The high honor from the Nuclear and Plasma Sciences Society of the Institute of Electrical and Electronics Engineers (IEEE) recognizes outstanding contributions to research and development in the field of fusion technology.
The U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has joined with five leading Chinese research institutions to form an international center to advance the development of fusion energy. Creators of the center organized its framework in March at a two-day session in Hefei, China, that brought together leaders of the world’s major fusion programs.
What is it like to be at the center of ITER, the huge international fusion experiment that is under construction in Cadarache, France? “It’s both exciting and challenging,” said physicist Rich Hawryluk, who recently returned to PPPL after a two-year stint as deputy director-general for the Administration Department of ITER. “It’s exciting in the scope and scale of this effort, and challenging in bringing such a large project to completion.”
The U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) has joined forces with researchers in South Korea to develop a pre-conceptual design for a pioneering fusion facility in that Asian nation. The proposed device, called K-DEMO, could be completed in the mid-to-late 2030s as the final step before construction of a commercial fusion power plant that would produce clean and abundant energy for generating electricity.
George "Hutch" Neilson manages PPPL’s international stellarator and tokamak collaborations. In that context, he is program manager and national point-of-contact for U.S. collaborations with the Wendelstein 7-X stellarator experiment in Germany, and a project manager for coil-design collaborations with the JET tokamak experiment in Oxfordshire, UK. Neilson also is the responsible manager for PPPL advanced design activities, and for planning for a next-generation experimental fusion facility, or DEMO, that is to precede a commercial fusion reactor.
