Fusion breakthrough: improved control of plasma

Futuretime.net 14th September 2018 Researchers have predicted the entire set of beneficial 3-D distortions for controlling edge localised modes (ELMs) in tokamak plasma. A long-time puzzle in the effort to capture the power of fusion is how to lessen or eliminate a common instability that occurs in the plasma called edge localised modes (ELMs). Just … Read moreFusion breakthrough: improved control of plasma

Extreme-Scale Code Models Extremely Hot Plasma to Explain Spontaneous Transition

DOE For the first time, scientists modeled the spontaneous bifurcation of turbulence to high-confinement mode, solving a 35-year-old mystery. Image courtesy of Princeton Plasma Physics Laboratory (Left) A typical plasma-density-fluctuation pattern from edge turbulence in a realistic tokamak geometry. The black line shows the magnetic separatrix surface with the magnetic X-point at the bottom. (Right) … Read moreExtreme-Scale Code Models Extremely Hot Plasma to Explain Spontaneous Transition

Scientists tame damaging plasma instabilities in fusion facilities

Space Daily Aug 23, 2018 Before scientists can capture and recreate the fusion process that powers the sun and stars to produce virtually limitless energy on Earth, they must first learn to control the hot plasma gas that fuels fusion reactions. In a set of recent experiments, scientists have tamed a plasma instability in a … Read moreScientists tame damaging plasma instabilities in fusion facilities
