This study overturns a dominant six-decade old notion that the giant magnetic field in a high intensity laser produced plasma evolves from the nanometre scale. Instead the field actually originates at macroscopic scales defined by the boundaries of the electron beam that is propagating in the plasma. This could alter our understanding of magnetic fields in astrophysics and laser fusion and may help in designing next generation high energy particle sources for imaging and therapies.

Infinitesimally low levels of radiation, such as from incoming cosmic rays, may soon stymie progress in quantum computing.

Researchers led by PPPL have upgraded a key computer code for calculating forces acting on magnetically confined plasma in fusion energy experiments. The upgrade will help scientists further improve the design of breakfast-cruller-shaped facilities known as stellarators.

Physicists at PPPL discover a new trigger for edge localized modes (ELMs) -- instabilities that can halt fusion reactions and damage the tokamaks that house such reactions.

Researchers discover a technique for widening the windows of plasma current to enhance suppression of edge localized modes (ELMs) that can damage tokamak facilities.

University of Cincinnati physicists, as part of an international research team, are raising doubts about the existence of an exotic subatomic particle that failed to show up in twin experiments.
