JET sets record in final round of experiments

In the Joint European Torus (JET)'s final deuterium-tritium experiments (DTE3), high fusion power was consistently produced for five seconds, resulting in a record of 69MJ using 0.2mg of fuel.

Over 300 scientists and engineers from EUROfusion – a consortium of researchers across Europe - contributed to these plasma science, materials science and neutronics-focussed experiments that took place between 31st August and 14th October, 2023 at the UK Atomic Energy Authority (UKAEA) site in Oxford.

In a statement, Professor Ambrogio Fasoli, programme manager (CEO) at EUROfusion, said: “Our successful demonstration of operational scenarios for future fusion machines, validated by the new energy record, instil greater confidence in the development of fusion energy. Beyond setting a new record, we achieved things we’ve never done before and deepened our understanding of fusion physics.”

Most approaches to creating commercial fusion favour the use of deuterium and tritium, two heavier variants of ordinary hydrogen that offer the highest reactivity of all fusion fuels.
