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.

Small but mighty: A mini plasma-powered satellite now under construction may launch a new era in space exploration

A tiny satellite under construction at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) could open new horizons in space exploration.  Princeton University students are building the device, called a cubic satellite, or CubeSat, as a testbed for a miniaturized rocket thruster with unique capabilities being developed at PPPL.

Seeing more clearly: Revised computer code accurately models an instability in fusion plasmas

Subatomic particles zip around ring-shaped fusion machines known as tokamaks and sometimes merge, releasing large amounts of energy. But these particles — a soup of charged electrons and atomic nuclei, or ions, collectively known as plasma — can sometimes leak out of the magnetic fields that confine them inside tokamaks. The leakage cools the plasma, reducing the efficiency of the fusion reactions and damaging the machine. Now, physicists have confirmed that an updated computer code could help to predict and ultimately prevent such leaks from happening.

Physicist Rajesh Maingi heads nationwide liquid metal strategy program for fusion devices

Rajesh Maingi, a world-renowned expert on the physics of plasma, has been named to co-lead a national program to unify research on liquid metal components for future tokamaks, doughnut-shaped fusion facilities. Maingi, who heads research on boundary physics and plasma-facing components at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), will coordinate the three-year project in conjunction with Oak Ridge National Laboratory and the University of Illinois at Urbana-Champaign.

Scientists deepen understanding of the magnetic fields that surround the Earth and other planets

Vast rings of electrically charged particles encircle the Earth and other planets. Now, a team of scientists has completed research into waves that travel through this magnetic, electrically charged environment, known as the magnetosphere, deepening understanding of the region and its interaction with our own planet, and opening up new ways to study other planets across the galaxy.

Discovered: A new way to measure the stability of next-generation magnetic fusion devices

Scientists seeking to bring to Earth the fusion that powers the sun and stars must control the hot, charged plasma — the state of matter composed of free-floating electrons and atomic nuclei, or ions — that fuels fusion reactions. For scientists who confine the plasma in magnetic fields, a key task calls for mapping the shape of the fields, a process known as measuring the equilibrium, or stability, of the plasma. At the U.S.
