This Conference was made particularly memorable in that experimental results from a new generation of fusion devices, the large tokamaks TFTR and JET, were reported for the first time in this series of conferences. It was also stimulated by its timeliness since many of the existing tokamak devices have reached an elevated state of machine capability and operational efficiency and have succeeded in raising their productivity. Thus, the achieved level of plasma performance parameters such as T, nτ, and nτT has readily surpassed the level of the preceding conferences, and the extent of experimental research carried out has allowed an improvement of plasma understanding and an exploration of the possibilities of new concepts.
