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.

PPPL physicists simulate innovative method for starting up tokamaks without using a solenoid

Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have produced self-consistent computer simulations that capture the evolution of an electric current inside fusion plasma without using a central electromagnet, or solenoid. The simulations of the process, known as non-inductive current ramp-up, were performed using TRANSP, the gold-standard code developed at PPPL. The results were published in October 2015 in Nuclear Fusion. The research was supported by the DOE Office of Science.

Discovering a previously unknown mechanism that halts solar eruptions before they blast into space

Among the most feared events in space physics are solar eruptions, massive explosions that hurl millions of tons of plasma gas and radiation into space. These outbursts can be deadly: if the first moon-landing mission had encountered one, the intense radiation could have been fatal to the astronauts. And when eruptions reach the magnetic field that surrounds the Earth, the contact can create geomagnetic storms that disrupt cell phone service, damage satellites and knock out power grids.

PPPL physicists win Torkil Jensen Award to conduct key experiments on DIII-D

Physicists Luis Delgado-Aparicio and Egemen Kolemen of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have won a national scientific competition to conduct a full day of experiments on the DIII-D National Fusion Facility that General Atomics operates in San Diego for the DOE. The honor, known as the Torkil Jensen Award, is named after the late and internationally recognized scientist who was a member of the General Atomics Fusion Group for 44 years.

COLLOQUIUM: Frontiers in Plasma Science: A High Energy Density Perspective

The potential for ground-breaking research in plasma physics in high energy density (HED) regimes is compelling. The combination of HED facilities around the world spanning microjoules to megajoules, with time scales ranging from femtoseconds to microseconds enables new regimes of plasma science to be experimentally probed. The ability to shock and ramp compress samples and simultaneously probe them allows dense, strongly coupled, Fermi degenerate plasmas relevant to planetary interiors to be studied.

Bernard named communications director of the Princeton Plasma Physics Laboratory

Larry Bernard, a proven developer of strategic communications programs, has been named director of communications for the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), effective December 14. PPPL is the nation’s leading center for the exploration of plasma science and magnetic fusion energy.
