The study of plasma, a partially-ionized gas that is electrically conductive and able to be confined within a magnetic field, and how it releases energy.

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.

Team led by PPPL’s Chang receives DOE 2015 INCITE award totaling 270 million core hours to study key problem in fusion

The U.S. Department of Energy has bestowed many hours of access to scientists at the Center for Edge Physics Simulation (EPSI), led by C.S. Chang, a physicist at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory. The highly competitive award allows 270 million core hours on two powerful supercomputers that will enable researchers to continue staging complex simulations of how charged particles behave in the tokamak edge. The award was the second highest in the INCITE program.

PPPL researchers present cutting edge results at APS Plasma Physics Conference

Some 135 researchers, graduate students, and staff members from PPPL joined 1,500 research scientists from around the world at the 56th annual meeting of the American Physical Society Division of Plasma Physics Conference from Oct. 27 to Oct. 31 in New Orleans. Topics in the sessions ranged from waves in plasma to the physics of ITER, the international physics experiment in Cadarache, France; to women in plasma physics. Dozens of PPPL scientists presented the results of their cutting-edge research into magnetic fusion and plasma science.

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.
