Quick Summary

The Joint European Torus (JET) is a significant nuclear physics facility focused on nuclear fusion. Nuclear fusion is the process where light atomic nuclei combine to form heavier ones, releasing substantial energy. This process is the source of power for stars.

JET is a tokamak, a type of experimental machine that uses magnetic fields to confine a high-temperature plasma. The goal is to replicate the conditions necessary for sustained fusion reactions, aiming to harness this energy for power generation. JET has achieved significant milestones, including producing over 10 megawatts of fusion power in experiments using deuterium and tritium. Research at facilities like JET is crucial for developing practical fusion reactors.12
