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.

Rob Goldston wins 2015 Nuclear Fusion Award for best paper published in 2012

The editorial board of the journal Nuclear Fusion has selected Rob Goldston, a fusion researcher and Princeton University professor of astrophysical sciences, as winner of the 2015 Nuclear Fusion Award. The award recognizes Goldston’s paper describing a new model for estimating the width of the scrape-off layer — the hot plasma that is exhausted in fusion facilities called tokamaks — as the most outstanding paper published by the journal in 2012.

Using powerful computers, physicists uncover mechanism that stabilizes plasma within tokamaks

A team of physicists led by Stephen Jardin of the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has discovered a mechanism that prevents the electrical current flowing through fusion plasma from repeatedly peaking and crashing. This behavior is known as a "sawtooth cycle" and can cause instabilities within the plasma's core. The results have been published online in Physical Review Letters. The research was supported by the DOE Office of Science.

PPPL scientists unveil their latest results at the 57th Annual Meeting of the American Physical Society Division of Plasma Physics

More than 1,750 researchers from around the world, including scientists from the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), have gathered in Savannah, Georgia, this week for the 57th Annual Meeting of the American Physical Society’s Division of Plasma Physics. Researchers at the five-day conference, which ends Nov. 20, will attend nine half-day sessions featuring nearly 1,000 talks on subjects ranging from space and astrophysical plasmas to the challenges of producing magnetic fusion energy.

design a high-resolution diagnostic system for the National Ignition Facility

Two U.S. Department of Energy (DOE) laboratories working on very different types of fusion experiments have begun a novel collaboration. Under the arrangement, the DOE’s Princeton Plasma Physics Laboratory (PPPL) will design a diagnostic system to provide high-resolution analysis of research on the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL). This work is supported by the DOE Office of Science and LLNL.

PPPL physicists find clue to formation of magnetic fields around stars and galaxies

An enduring astronomical mystery is how stars and galaxies acquire their magnetic fields. Physicists Jonathan Squire and Amitava Bhattacharjee at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have found a clue to the answer in the collective behavior of small magnetic disturbances. In a paper published in October in Physical Review Letters, the scientists report that small magnetic perturbations can combine to form large-scale magnetic fields just like those found throughout the universe. This research was funded by the DOE Office of Science.
