Figure-eight shaped tubes that confine hot plasma with external magnetic fields, developed by Lyman Spitzer in 1950 at the lab that became the PPPL.

Permanent magnets far stronger than those on refrigerator doors could be a solution for delivering fusion energy

Permanent magnets akin to those used on refrigerators could speed the development of fusion energy – the same energy produced by the sun and stars.

In principle, such magnets can greatly simplify the design and production of twisty fusion facilities called stellarators, according to scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute for Plasma Physics in Greifswald, Germany. PPPL founder Lyman Spitzer Jr. invented the stellarator in the early 1950s.

Design of the W7-X fusion device enables it to overcome obstacles, scientists find

A key hurdle facing fusion devices called stellarators — twisty facilities that seek to harness on Earth the fusion reactions that power the sun and stars — has been their limited ability to maintain the heat and performance of the plasma that fuels those reactions. Now collaborative research by scientists at the U.S.

Ten not-to-be-missed PPPL stories from 2019 — plus a triple bonus!

Arms control robots, a new national facility, and accelerating the drive to bring the fusion energy that powers the sun and stars to Earth. These far-reaching achievements at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) made 2019 another remarkable year. Research at the only national laboratory devoted to fusion and plasma physics — the state of matter that makes up 99 percent of the visible universe — broke new ground in varied fields as vast as astrophysics and as tiny as nanotechnology.

New technique could streamline design of intricate fusion device

Stellarators, twisty machines that house fusion reactions, rely on complex magnetic coils that are challenging to design and build. Now, a physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has developed a mathematical technique to help simplify the design of the coils, making stellarators a potentially more cost-effective facility for producing fusion energy.

Ten PPPL stories you may have missed from 2018 — plus a special bonus

From new insights into the control of nuclear fusion to improved understanding of the fabrication of material thousands of time thinner than a human hair, the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) achieved wide-ranging advances in 2018. Research at the Laboratory focuses on the physics of plasma, the state of matter composed of free electrons and atomic nuclei that fuels the fusion reactions that light the sun and stars and underlies fundamental processes throughout the cosmos.
