COLLOQUIUM: Motivations for Spherical Torus research and initial results from NSTX Upgrade

The Spherical Torus/Tokamak (ST) is being explored as a possible means of accelerating the development of magnetic fusion energy. The ST offers access to a higher ratio of plasma pressure to magnetic field pressure and extends toroidal confinement physics understanding including support for ITER burning plasma physics. The ST may also provide an attractive configuration for fusion applications including plasma-material-interface solution development, fusion nuclear component testing, and a net-electricity producing Pilot Plant. The NSTX Upgrade (NSTX-U) facility at PPPL supports all of t

PPPL senior physicist Wei-li Lee honored at week-long symposium

Physicists from around the world gathered at the University of California, Irvine this past summer for a symposium in honor of Wei-li Lee, a senior physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL). The week-long event, held from July 18-22, focused on gyrokinetic simulation — a technique Lee invented in the 1980s to model the behavior of particles within plasma, the ultrahot gas composed of electrons and atomic nuclei that fuels fusion reactions.

PPPL physicists build diagnostic that measures plasma velocity in real time

Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a diagnostic that provides crucial real-time information about the ultrahot plasma swirling within doughnut-shaped fusion machines known as tokamaks. This device monitors four locations in a plasma, enabling the diagnostic to make rapid calculations of how the velocity profiles of ions inside the plasma evolves over time.

PPPL physicists win funding to lead a DOE exascale computing project

A proposal from scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) has been chosen as part of a national initiative to develop the next generation of supercomputers. Known as the Exascale Computing Project (ECP), the initiative will include a focus on exascale-related software, applications, and workforce training.

First results of NSTX-U research operations presented at the International Atomic Energy Agency Conference in Kyoto, Japan

Researchers from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratories (PPPL) and collaborating institutions presented results from research on the National Spherical Torus Experiment Upgrade (NSTX-U) last week at the 26^th International Atomic Energy Agency Conference (IAEA) in Kyoto, Japan. The four-year upgrade doubled the magnetic field strength, plasma current and heating power capability of the predecessor facility and made the NSTX-U the most powerful fusion facility of its kind.
