New simulations confirm efficiency of waste-removal process in plasma device

Princeton Plasma Physics Laboratory

PPPL scientists have found evidence suggesting that a process could remove the unwanted ash produced during fusion reactions and make the fusion processes more efficient within a type of fusion facility known as a field-reversed configuration device.

No Longer Whistling in the Dark: Scientists Uncover a Little-Understood Source of Waves Generated Throughout the Universe

Princeton Plasma Physics Laboratory

Scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and other laboratories, using data from a NASA four-satellite mission that is studying reconnection, have developed a method for identifying the source of waves that help satellites determine their location in space.

Separating the Sound from the Noise in Hot Plasma Fusion

American Institute of Physics (AIP)

For fusion power plants to be effective, scientists must find a way to trigger the low-to-high confinement transition, or “L-H transition” for short. Scientists have observed that the L-H transition is always associated with zonal flows of plasma. Theoretically, zonal flows in a plasma consist of both a stationary flow with a near-zero frequency and one that oscillates at a higher frequency called the geodesic acoustic mode. For the first time, researchers have detected GAM at two different points simultaneously within the reactor. This new experimental setup will be a useful diagnostic tool for investigating the physics of zonal flows, and their role in the L-H transition. The researchers report these findings in a new paper published in Physics of Plasmas.
