Abstract

The main thrust of JET operation during 1990 was to exploit further the different regimes of plasma behaviour previously observed in JET, to explore the superposition of these to maximise fusion performance, and to elucidate the physical processes underlying this performance. The operation was preceded by a shut-down during which major up-grades were implemented and new systems installed. The experimental objectives, therefore, were to exploit the new systems and enhancements and to expose to experimental test critical choices such as materials for the X-point targets, as well as to maximise fusion performance. Enhancements of machine and in-vessel systems, heating, fuelling and diagnostic systems, and greater operational reliability, together resulted in the improvements in plasma performance reported.
