This paper reports the first Deuterium-Tritium (D-T) fusion experiments in the geometry of the International Thermonuclear Reactor (ITER) (R. Aymar, V. Chuyanov, M. Huguet, R. Parker, Y. Shimamura, and the ITER Joint Central Team and Home Teams, Proceedings of the 16th International Conference on Fusion Energy (International Atomic Energy Agency (IAEA), Vienna), Fusion Energy 1 ( 1996) 3 ), with long pulse length and an ITER-like divertor. Physics aspects, such as the isotope dependence of confinement, the H-mode threshold, shear optimisation, heating methods, high fusion performance and alpha particle heating, are discussed together with their implications. The technology aspects of tritium wall loading and clean-up, the close coupled tritium plant and the future remote handling divertor target exchange are also mentioned.
