New high-performance computing cluster will greatly enhance PPPL and Princeton University research

Stellar, a computing cluster that Princeton University is installing in its High-Performance Computing Research Center, will sharply advance research at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) to bring to Earth the fusion energy that powers the sun and stars. The computer, which the Laboratory will share with a broad range of University departments, will be available to the entire PPPL scientific community including engineers.

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.

Extreme-scale computing and AI help forecast a promising outlook for divertor heat-loads in next-step fusion reactors

Efforts to duplicate on Earth the fusion reactions that power the sun and stars for unlimited energy must contend with extreme heat-load density that can damage the doughnut-shaped fusion facilities called tokamaks, the most widely used laboratory facilities that house fusion reactions, and shut them down.

New machine learning theory that can be applied to fusion energy raises questions about the very nature of science

A novel computer algorithm, or set of rules, that accurately predicts the orbits of planets in the solar system could be adapted to better predict and control the behavior of the plasma that fuels fusion facilities designed to harvest on Earth the fusion energy that powers the sun and stars.

“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.
