The Joint European Torus (JET), one of the world's largest and most powerful fusion machines, has made history by demonstrating the reliable generation of fusion energy while setting a world-record in energy output. In its final deuterium-tritium experiments (DTE3), JET consistently produced high fusion power for 5 seconds, achieving a groundbreaking record of 69 megajoules with just 0.2 milligrams of fuel.

JET, a tokamak design utilizing powerful magnetic fields to confine plasma in a doughnut shape, showcased the potential of fusion energy by utilizing deuterium and tritium to produce helium and vast amounts of energy. This breakthrough represents a significant milestone in the field of fusion science and engineering.

The success of JET's operational scenarios for future fusion machines like ITER and DEMO, coupled with the validation of the new energy record, instills confidence in the development of fusion energy. The collaborative efforts of over 300 scientists and engineers from EUROfusion at the UK Atomic Energy Authority site in Oxford have been instrumental in advancing safe, low-carbon, and sustainable fusion energy.

The achievements at JET highlight its crucial role in accelerating the development of fusion technology, paving the way for a future energy supply that is safe, low-carbon, and sustainable. As JET transitions into the next phase of its lifecycle, its legacy in fusion science and engineering remains unparalleled.
