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.

Rob Goldston, Alex Glaser and Boaz Barak named among Foreign Policy magazine’s 100 top global thinkers

Editors of Foreign Policy magazine have named fusion physicist Rob Goldston, a Princeton University professor of astrophysical sciences and former director of PPPL, to its list of  “100 Leading Global Thinkers of 2014.” The recognition, made Nov. 17 at a celebration in Washington, D.C., honored Goldston for his contributions to the field of nuclear arms control.

Bob Ellis designs a PPPL first: A 3D printed mirror for microwave launchers

When scientists at the Korea Supercomputing Tokamak Advanced Research (KSTAR) facility needed a crucial new component, they turned to PPPL engineer Bob Ellis. His task: Design a water-cooled fixed mirror that can withstand high heat loads for up to 300 seconds while directing microwaves beamed from launchers to heat the plasma that fuels fusion reactions.

PPPL successfully tests system for mitigating instabilities called “ELMs”

PPPL has successfully tested a Laboratory-designed device to be used to diminish the size of instabilities known as “edge localized modes (ELMs)” on the DIII–D tokamak that General Atomics operates for the U.S. Department of Energy in San Diego. Such instabilities can damage the interior of fusion facilities.

The PPPL device injects granular lithium particles into tokamak plasmas to increase the frequency of the ELMs. The method aims to make the ELMs smaller and reduce the amount of heat that strikes the divertor that exhausts heat in fusion facilities.

“Rip” Perkins, pioneering PPPL physicist and a design leader for ITER, dies at 80

Francis “Rip” William Perkins Jr., a pioneering plasma physicist whose contributions to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) ranged from seminal advances in fusion energy and astrophysical research to the education of a generation of scientists, died on July 26 in Boulder, Colo. He was 80 and had long battled Parkinson’s disease.
