Abstract

In 1985 a laser blowoff system was installed on the ASDEX Tokamak and in the following period a number of experiments were performed. The idea of these investigations was to study the impurity behaviour under different plasma conditions. New and unexpected results were obtained: considerable improvement of the impurity confinement time in OH plasmas near to the density limit influence on ELMs by impurities strong dependence of the purity confinement time on the gradient of the plasma current different impurity confinement under various heating conditions.
