Renowned fusion laboratory honors pioneering physicist Richard J. Hawryluk

For more than 40 years Rich Hawryluk has been a guiding light and solver of nearly intractable problems at PPPL. His countless accomplishments have supported and enhanced the role of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) as the center of world-class research on harvesting on Earth the fusion energy that powers the sun and stars. 

Scientists collaborate on public-private partnership to facilitate the development of commercial fusion energy

The U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) is collaborating with private industry on cutting-edge fusion research aimed at achieving commercial fusion energy. This work, enabled through a public-private DOE grant program, supports efforts to develop high-performance fusion grade plasmas.

Advisory Committee Releases Long-Range Plan for U.S. Fusion Energy Sciences Program

A subcommittee convened by the U.S. Department of Energy (DOE) Fusion Energy Sciences Advisory Committee (FESAC) to develop a long-range plan for FES has released its final report that lays out a strategic plan for fusion energy and plasma science research over the next decade. The report has been two years in the making, gathering an unprecedented level of input and support from across the diverse U.S. fusion energy and plasma sciences community. Its strategic plan charts a path for the U.S. as it seeks to develop fusion as a limitless and practical source of energy.

PPPL awarded $4 million to simplify design and construction of stellarator fusion energy facilities

The U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has been awarded the lead role in a grant worth $3 million in DOE Advanced Research Projects Agency-Energy (ARPA-E) funding for the design and construction of permanent magnets far more powerful than those on refrigerator doors to facilitate the development of fusion energy. Such magnets could provide a highly innovative basis for simplifying stellarators, complex facilities for experiments in producing fusion energy.

PPPL presents discoveries and plays a prominent role at global physics gathering

Scientific discoveries, educational opportunities and wide-ranging events highlighted the 62nd American Physical Society-Division of Plasma Physics annual meeting, which attracted participants from around the world. The session this year, held virtually November 9 to  13, drew more than 150 physicists, engineers and students from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL).
