Both for widening the understanding of the physics involved in the exhaust issue and for exploring possible alternative or complementing methods of exhausting particle and power, studies are also being undertaken on other concepts, in particular limiter concepts, the ergodic divertor, and the island divertor foreseen for Stellarators (see e.g. W7-X). An additional advantage of this programme strategy is the fact that (i) synergisms exist between different approaches and concepts and (ii) most methods and processes (like diagnostics, wall treatment, modelling, heating) which are developed on one system can be transferred to the others. The stimulating results from the $\textbf{Ergodic Divertor (ED)}$ of TORE SUPRA (Association EURATOM-CEA Cadarache), as well as the ideas and experiments of Takamura et al. have inspired KFA-Jülich and its partners to develop the concept of the $\textbf{Dynamic Ergodie Divertor (DED)}$. The Association EURATOM-KFA Jülich, therefore, proposes to build and install such a system in TEXTOR-94 as an integral part of the research programme of the Trilateral Euregio Cluster (TEC). The beneficial effects of an $\textbf{ED}$, among which improved radiation efficiency of impurities and better impurity screening (TORE SUPRA) are the most significant ones, are due to the combined effects of increased electron density and decreased electron temperature at the plasma boundary in conjunction with enhanced radial transport and reduced sputtering ofimpurities. In the "near field" region ofthe helical coils (creating the multipolar perturbation field) the magnetic field lines are displaced radially even without resonances and ergodization.
