Joint European Torus

JET, the Joint European Torus, is the world's largest magnetic confinement plasma physics experiment, located at Culham Science Centre in Oxfordshire, UK. Based on a tokamak design, the fusion research facility is a joint European project with a main purpose of opening the way to future nuclear fusion grid energy. More advanced facilities are being developed to follow on the JET research, including ITER and :DEMO.
==Construction==
The JET facilities are situated on a former Navy airfield near Culham, Oxfordshire – RNAS Culham (HMS Hornbill), in the UK. They are located alongside Culham Centre for Fusion Energy (the UK's fusion research laboratory, which opened in 1965). The construction of the buildings which house the project was undertaken by Tarmac Construction,〔Berry Ritchie, ''The Story of Tarmac'' Page 100, Published by James & James (Publishers) Ltd, 1999〕 starting in 1978 with the Torus Hall being completed in January 1982. Construction of the JET machine itself began immediately after the completion of the Torus Hall, with the first plasma experiments in 1983.
The components for the JET machine came from manufacturers all over Europe, with these components transported to the site.
Because of the extremely high power requirements for the tokamak, and the fact that power draw from the main grid is limited, two large flywheel generators were constructed to provide this necessary power. Each 775 ton flywheel can spin up to 225 rpm. One generator provides power for the 32 toroidal field coils, the other for inner poloidal field coils. The outer field coils draw their power from the grid.
