Joint European Torus (JET)

The Joint European Torus (JET) is a large scientific device located in the UK designed to study nuclear fusion—the process that powers the Sun. It uses powerful magnetic fields to contain and control a super-hot plasma of hydrogen isotopes, enabling researchers to replicate and study fusion reactions on Earth. The goal is to develop a clean, abundant energy source by harnessing fusion power safely and efficiently, providing insights that could help pave the way for future fusion reactors. JET is one of the most advanced machines of its kind, contributing valuable data toward achieving sustainable fusion energy.
