Energy that originates from the splitting of uranium atoms in a process called fission. This is distinct from a process called fusion where energy is released when atomic nuclei combine or fuse.

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.

Preventing damaging heat bursts at the edge of fusion plasmas

In a fusion energy device that creates a “star in a jar,” bursts of intense heat can damage the walls of the jar that holds the superhot plasma fueling fusion reactions. Fusion scientists now have shown that an innovative new model can serve as the basis for predicting the suppression of such outbursts in the DIII-D National Fusion Facility that General Atomics operates in San Diego.

Public-private INFUSE projects to speed fusion development housed at PPPL

State-of-the-art computer codes and world-class expertise at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) will provide four of the first 12 collaborations under the newly created Innovation Network for Fusion Energy (INFUSE) program. The public-private partnerships, funded by the DOE Office of Science, are intended to speed the development on Earth of the fusion energy that powers the sun and stars.

PPPL physicist Stoltzfus-Dueck will explore the performance of fusion plasma with an Early Career Research Award

Timothy Stoltzfus-Dueck, a theoretical physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), has won a DOE Early Career Research Award for exceptional scientists in the early stages of their careers. Stoltzfus-Dueck will use the five-year, approximately $500,000 per year award to develop and test models essential to the confinement of plasma, the hot, charged gas that must be tightly confined in doughnut-shaped devices to produce fusion reactions.

Graduate student plasma physicist Alexander Glasser wins Princeton University Fellowship

Graduate student Alexander Glasser, who arrived at the Program in Plasma Physics at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) after nearly a decade working on Wall Street, has won a highly competitive Charlotte Elizabeth Procter Honorific Fellowship from Princeton University. The fellowship provides full tuition and a stipend for the 2019-2020 academic year for students “displaying the highest scholarly excellence in graduate work.”

Discovered: A new way to measure the stability of next-generation magnetic fusion devices

Scientists seeking to bring to Earth the fusion that powers the sun and stars must control the hot, charged plasma — the state of matter composed of free-floating electrons and atomic nuclei, or ions — that fuels fusion reactions. For scientists who confine the plasma in magnetic fields, a key task calls for mapping the shape of the fields, a process known as measuring the equilibrium, or stability, of the plasma. At the U.S.
