A nuclear fusion reactor in which a magnetic field keeps charged, hot plasma moving in a doughnut-shaped vacuum container.

New computer model helps bring the sun into the laboratory

Every day, the sun ejects large amounts of a hot particle soup known as plasma toward Earth where it can disrupt telecommunications satellites and damage electrical grids. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University’s Department of Astrophysical Sciences have made a discovery that could lead to better predictions of this space weather and help safeguard sensitive infrastructure.

Fooling fusion fuel: How to discipline unruly plasma

The process designed to harvest on Earth the fusion energy that powers the sun and stars can sometimes be tricked. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics laboratory have derived and demonstrated a bit of slight-of-hand called “quasi-symmetry” that could accelerate the development of fusion energy as a safe, clean and virtually limitless source of power for generating electricity.

Found: A fast and accurate way to optimize fusion energy devices

A model once thought to be nearly impossible for quickly and accurately designing radio frequency (RF) waves needed to fire up doughnut-shaped tokamak fusion facilities has been developed by a graduate student at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The student, Nick Lopez, has innovated a fast and accurate way to calculate the energy and path of RF waves that are distorted by roadblocks called “caustics” that make the behavior of the waves highly complex.

Research confirms ingredient in household cleaner could improve fusion reactions

Want to improve your chances of making electricity from fusion? Look no further than the cleaners under your kitchen sink.

Research led by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) provides new evidence that particles of boron, the main ingredient of Borax household cleaner, can coat internal components of doughnut-shaped plasma devices known as tokamaks and improve the efficiency of the fusion reactions.

Scientists find clues to a process occurring throughout the universe that affects fusion energy

New research reveals a surprising insight into the physics behind magnetic reconnection, a process occurring through the universe that converts magnetic to kinetic energy. The findings, by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) together with other physicists, could lead to a greater ability to predict space weather — fast particles from the sun that can disrupt communications satellites and electrical networks.

Exploring Women’s History Month: A PPPL researcher discusses her perspective

As the Princeton Plasma Physics Laboratory celebrates International Women’s Day March 8 and Women’s History Month throughout March, we asked some of our staff members to tell us what Women’s History Month means to them. This is the first of a weekly series throughout March.

New high-performance computing cluster will greatly enhance PPPL and Princeton University research

Stellar, a computing cluster that Princeton University is installing in its High-Performance Computing Research Center, will sharply advance research at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) to bring to Earth the fusion energy that powers the sun and stars. The computer, which the Laboratory will share with a broad range of University departments, will be available to the entire PPPL scientific community including engineers.
