As we hail and say a fond farewell to JET, and to celebrate all its landmark progress throughout the decades, we have complied a selection of some images.
Do you have a favourite memory of JET? Let us know in the comments.
Some of JET’s milestones, include:
• 1983: First plasma
• 1984: Official opening by Her Majesty Queen Elizabeth II, M. François Mitterrand (President of the French Republic) and M. Gaston Thorn (President of the European Commission)
• 1991: First deuterium-tritium plasma created; record 1.8 megawatts reached
• 1997: First deuterium-tritium experiments and world record 16.1 megawatts and 21.7 megajoules
• 2011: ITER-like metal wall installation completed
• 2021: Second deuterium-tritium experiments and world record for sustained fusion energy at high power producing 59 megajoules over 5 seconds, demonstrating fusion power plant potential
• 2023: JET DT3 campaign produced a world record for most fusion energy released in a single pulse - 69 megajoules in a 6-second long pulse.

UKAEA’s mission is to deliver sustainable fusion energy and maximise scientific and economic impact. Fusion, the process that powers the sun, can play a big part in our carbon-free energy future.
UKAEA leads the world in fusion research with a wide range of programmes covering robotics, materials testing and development, and tritium science. Our scientists and engineers are working with partners around the globe to develop fusion as a new source of clean energy for tomorrow’s power stations.
