New Clues to Improving Fusion Confinement

Nuclear fusion — when two nuclei combine to form a new nucleus, thereby releasing energy — may be the clean, reliable, limitless power source of the future. But first, scientists must learn how to control its production. Building on decades of prior research, scientists have developed sophisticated techniques to improve…

Closing In on Fusion

The same process that fuels stars could one day be used to generate massive amounts of power here on Earth. Nuclear fusion—in which atomic nuclei fuse to form heavier nuclei and release energy in the process—promises to be a long-term, sustainable, and safe form of energy. But scientists are still trying to fine-tune the process of…

Weighing up Plasma Particles

The sun’s energy is the result of a continuous series of nuclear fusion reactions in which ionized hydrogen in the form of plasma collides at high speeds and releases helium and energetic neutrons—producing enormous bursts of energy in the process. For years, researchers have sought a way to harness this…
