Abstract.  Abstract: The focus of the JET programme is to investigate issues that may affect ITER design and operation. From that point of view, there has been progress in: the consolidation of the ELMy H-mode scenario, achieving stationary conditions with simultaneous high confinement, density and beta; in NTM and ELM studies; in LHCD coupling, producing plasmas with strongly reversed shear, leading to high performance ITBs, and to quasi-stationary conditions, with real time control of the plasma; and in further understanding of material migration amongst plasma facing components. Related investigations have brought a wealth of information on tokamak plasma behaviour: plasmas with ``current holes'' were observed for the first time in JET; analysis of electron runaway production after disruptions shows that avalanche processes are important; Alfvén cascades were studied in reversed shear plasmas; investigation of ICRH induced rotation challenges theory; ICRH heating of beam injected 4He provided a new tool for simulation of fusion alphas; modelling and simulation of microturbulence, transport, SOL and MHD are exploited to understand internal and edge barriers, cold pulses, ELM power loads.
