Isotope movement holds key to the power of fusion reactions

(National Institutes of Natural Sciences) Controlling the uniformity of hydrogen isotope density ratio in fusion plasma is a problem for realizing fusion energy. The researchers have reached a key understanding of the process to make the hydrogen isotope ratio uniform using the Large Helical Device at the National Institute for Fusion Science. The uniformity is determined by isotope movement under the influence of plasma turbulence. This understanding would help researchers to increase the power...
