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.

Hong Qin promoted to executive dean at the University of Science and Technology of China

Hong Qin bestrides the globe as a leading scientist and educator. For the past four years he has shuttled between PPPL and a teaching post at the University of Science and Technology of China (USTC), which named him executive dean of its School of Nuclear Science and Technology in October. Hong takes up the position while maintaining his agenda as a principal research physicist in the PPPL Theory Department and his teaching in the Program in Plasma Physics at Princeton University, where he is a lecturer with the rank of professor in the Department of Astrophysical Sciences.

Monumental effort: How a dedicated team completed a massive beam-box relocation for the NSTX upgrade

Your task: Take apart, decontaminate, refurbish, relocate, reassemble, realign and reinstall a 75-ton neutral beam box that will add a second beam box to the National Spherical Torus Experiment-Upgrade (NSTX-U) and double the experiment’s heating power. Oh, and while you’re at it, hoist the two-story tall box over a 22-foot wall.

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.
