The European Joint Fusion Experimental Facility (JET) in Oxfordshire, UK, has generated 59 megajoules of energy in a five-second nuclear fusion experiment, smashing its previous record, the Cullum Fusion Energy Centre under the UK Atomic Energy Authority announced On Tuesday.The experiment, which took place on December 21, 2021, produced more than twice as much sustained energy as a similar experiment carried out in 1997, when the device set a record of 21.7 megajoules.”This is a landmark achievement and a significant boost to the International Thermonuclear Fusion Experimental Reactor,” the Callum Fusion Energy Center said in a statement.The International Thermonuclear Fusion Experimental Reactor (ITER) Project is jointly implemented by China, the European Union, India, Japan, the Republic of Korea, Russia and the United States.The plan is to build the world’s largest tokamak installation in the south of France.The Tokamak device is a circular device that uses magnetic confinement to achieve controlled nuclear fusion.JET is located at the Callum Fusion Energy Centre and its scientific operations are run by the European Federation for the Development of Fusion Energy.It is the world’s largest tokamak installation and is seen as an important test bed for ITER.During the experiment, the donut shaped JET heated a gas composed of hydrogen isotopes to 150 million degrees Celsius and used a magnetic field to trap the hot plasma it formed.At high temperatures and pressures, isotopes of hydrogen fuse to form helium, releasing energy in the form of neutrons.To break the energy record, the experiment used a mixture of deuterium and tritium, two isotopes of hydrogen.”Deuterium-tritium fusion” produces far more neutrons than pure deuterium fusion, increasing energy release.The ITER device, which is still under construction, also plans to use a mixture of deuterium and tritium as fusion fuel.Anne White, a plasma physicist at the Massachusetts Institute of Technology, said the experiment was the result of nearly 20 years of work and was important in helping to predict and guide ITER’s operation.Nuclear fusion is expected to provide mankind with almost unlimited clean energy and is crucial to solving the global energy crisis.The success of the experiment is a step towards harnessing fusion energy in the future.Ian Chapman, chief executive of the UK Atomic Energy Authority, said: “It is clear that we must make major changes to tackle climate change and fusion offers such huge potential.”
