JET

JET, the Joint European Torus, is the world's largest operational magnetically confined plasma physics experiment, located at Culham Centre for Fusion Energy 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. Four coils have been built and installed in 1992 by the Company in the JET vacuum vessel for the plasma containment. The coils are made of copper with glass epoxy insulation and are enclosed in vacuum tight Inconel case. At the Company’s factory, the coil parts were manufactured and process techniques qualified. In the JET vacuum vessel the conductors bars were brazed to form the coils, which were inserted in the casings and impregnated and cured with epoxy resin. Such operations were performed in radioactive ambient.
