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.

PPPL Physicist Richard Hawryluk to chair the Nuclear Fusion editorial board

Richard Hawryluk, a distinguished physicist who heads the ITER and Tokamaks department at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has been named chair of the board of editors of Nuclear Fusion, the leading monthly journal in the field of controlled fusion energy. Announcement of the appointment came during the 2016 International Atomic Energy Agency (IAEA) Nuclear Fusion Energy Conference in Kyoto, Japan.

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.

PPPL inventors honored for device that creates medical isotope vital for diagnosing diseases

A team of scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has won the 2016 Edison Patent Award for inventing an on-demand method to create a badly needed isotope used routinely in medical imaging devices to diagnose diseases such as cancer and heart disease.

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.

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 and Princeton demonstrate novel technique that may have applicability to future nuclear disarmament agreements

A system that can compare physical objects while potentially protecting sensitive information about the objects themselves has been demonstrated experimentally at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). This work, by researchers at Princeton University and PPPL, marks an initial confirmation of the application of a powerful cryptographic technique in the physical world.
