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 26th 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.

COLLOQUIUM: What is the Fusion Nuclear Science Facility, What Does it Do, Why do We Need It...the Critical First Step Toward Power Plants

For fusion research to take the step beyond ITER it will have to embrace the fusion nuclear science along with fusion plasma science.   The hardware that surrounds and supports the plasma will become part of the challenge for research and development since fusion power plants will rely on these structures to recover the power emitted, breed the tritium fuel, provide neutron and gamma shielding, and provide the magnetic fields and the vacuum environment the plasma requires.  The Fusion Nuclear Science Facility (FNSF) is a fusion nuclear device that is considered as the first step in a

Steven Sabbagh leads study to predict and avoid disruptions on KSTAR plasmas

Steven Sabbagh, a senior research scientist at Columbia University on long-term assignment to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), has been named lead principal investigator for a multi-institutional project on the Korea Superconducting Tokamak Advanced Research (KSTAR) facility. The three-year, $3.3 million collaboration will study methods of predicting and avoiding disruptions on KSTAR, a long-pulse tokamak that produces plasmas that can last from 30 seconds to a design value of more than five minutes.

PPPL researchers successfully test new device that analyzes the surfaces of tokamak components within a vacuum

Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have successfully tested a new device that will lead to a better understanding of the interactions between ultrahot plasma contained within fusion facilities and the materials inside those facilities. The measurement tool, known as the Materials Analysis Particle Probe (MAPP), was built by a consortium that includes Princeton University and the University of Illinois at Urbana-Champaign (U. of I.).
