Abstract

This paper presents the rationale behind the JET Joint Undertaking since 1978. JET, the Joint European Torus, is the largest machine in operation using the toroidal tokamak configuration of magnetic confinement as the basis for controlled thermonuclear fusion. Recent work on impurities and density control have improved the performance of JET, mainly by the introduction of beryllium as a material for first wall components and coatings. The underlying JET results are significant for the formulation of a model of transient and steady state plasmas that can be used for moderate extrapolation to a Next Step tokamak. The paper concludes with an analysis of the issues to be resolved, which are identified as long burn ignition, concept optimisation and materials testing, before the construction of a first reactor.
