A key challenge to capturing and controlling fusion energy on Earth is maintaining the stability of plasma—the electrically charged gas that fuels fusion reactions—and keeping it millions of degrees hot to launch and maintain fusion reactions. This challenge requires controlling magnetic islands, bubble-like structures that form in the plasma in doughnut-shaped tokamak fusion facilities. These islands can grow, cool the plasma and trigger disruptions—the sudden release of energy stored in the plasma—that can halt fusion reactions and seriously damage the fusion facilities that house them.
