FUSION ENERGY: HOW SCIENTISTS ARE CREATING PLASMA HOTTER THAN THE SUN IN QUEST FOR LIMITLESS CLEAN ENERGY

Newsweek BY HANNAH OSBORNE ON 10/23/17 Scientists believe that fusion energy—which generates electricity in the same way that the sun creates energy—has the potential to provide the world with an almost limitless, clean source of power. But while it is known that fusing two lighter atomic nuclei to form a heavier nucleus releases energy, it … Read more

World’s Biggest Science Project Feels the Heat From Renewables

Washington Post Anna Hirtenstein | Oct 20, 2017 (Bloomberg) — The world’s biggest scientific experiment is on course to become the most expensive source of surplus power. Components of the 20 billion-euro ($24 billion) project are already starting to pile up at a construction site in the south of France, where about 800 scientists plan … Read more

Multiscale simulations help predict unruly plasma behavior

Phys.org September 21, 2017 by Kathy Kincade Visualization of temperature fluctuations from a high-resolution simulation of a plasma discharge in the DIII-D tokamak. The DIII-D plasma was designed to match many of the plasma parameters targeted in ITER operation. Credit: Chris Holland Decades of fusion research have brought many advances in our understanding of the … Read more

The blob that ate the tokamak: Physicists gain understanding of how bubbles at the edge of plasmas can drain heat and reduce fusion reaction efficiency

PPPL By Raphael Rosen | October 19, 2017 PPPL Physicist Michael Churchill To fuse hydrogen atoms into helium, doughnut-shaped devices called tokamaks must maintain the heat of the ultrahot plasma they control. But like boiling water, plasma has blobs, or bubbles, that percolate within the plasma edge, reducing the performance of the plasma by taking … Read more

Meet the scientists who want to harness the power of the Sun

The Weather Network by Scott Sutherland | September 19, 2017 Fusion is the power source of the future, according to science fiction, but did you know that scientists have been working on this for decades, and are drawing ever closer to harnessing the power of the Sun? What is Fusion Power? When we look up … Read more

Loops of liquid metal can improve future fusion power plants, scientists say

Phys.org October 17, 2017 Physicist Masa Ono with images reported in Nuclear Fusion paper. Credit: Elle Starkman/PPPL Office of Communications Researchers led by the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have proposed an innovative design to improve the ability of future fusion power plants to generate safe, clean and abundant energy … Read more

Generalised ballooning theory of two dimensional tokamak modes

arcXiv P. A. Abdoul, D. Dickinson, C. M. Roach, H. R. Wilson (Submitted on 12 Oct 2017) In this work, using solutions from a local gyrokinetic flux-tube code combined with higher order ballooning theory, a new analytical approach is developed to reconstruct the global linear mode structure with associated global mode frequency. In addition to … Read more

PPPL takes detailed look at 2-D structure of turbulence in tokamaks

PPPL October 13, 2017 Correlation analysis of three plasma discharges on NSTX for each of five different radial locations near the plasma edge. The red regions marked with a blue cross have high positive correlation around the origin point, while the blue regions marked with a yellow cross have high negative correlation.
