National panel chaired by PPPL expert urges the government and private sector to produce net electricity in fusion pilot plant by 2035-2040

The U.S. should immediately invest in resolving the scientific and technical issues in designing and building a fusion-powered pilot plant to operate in the 2035-2040 time range as a stepping stone to a commercial fusion plant that would fire up by 2050. Calling for the acceleration was a 93-page report put together by a panel of the National Academies of Sciences, Engineering, and Medicine (NASEM) chaired by Richard J. Hawryluk, associate director for fusion at the U.S.

“The Renaissance of the Stellarator” is unveiled at first 2021 Science on Saturday lecture

The twisty plasma fusion device known as the stellarator was first envisioned by Lyman Spitzer, the founder of the Princeton Plasma Physics Laboratory (PPPL), 70 years ago as a way to harness the energy of the stars in a bottle. Now, the concept of using stellarators as a clean, affordable and abundant way to produce electricity is making a comeback, physicist David Gates said at PPPL’s first Ronald E. Hatcher Science on Saturday lecture of the year on Jan. 9.

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).
