Single X-ray pulse reveals plasma nanostructures across scales with one camera
Researchers have developed a new X-ray scattering method to observe plasma nanostructures in high-energy-density environments. This technique allows for single-shot measurements that capture rapid changes in plasma turbulence and instability.
Why it matters
Improving the ability to measure plasma dynamics is critical for advancing research in nuclear fusion, astrophysics, and laser-plasma physics.

Credit: National Institute for Fusion Science Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In plasmas, slight disturbances can grow due to instabilities, and energy is transferred between structures of various sizes due to turbulence. These phenomena give rise to structures ranging from very small to large, which significantly influence the overall motion and energy flow of the plasma.
