The Dynamic Ergodic Divertor (DED) has recently been taken into operation on the TEXTOR tokamak. The main aim in this context is the study of its divertor properties. After an introduction into the theory of ergodization, the design of the DED is presented. The Chirikov parameter describing the level of ergodization reaches a level of up to four if the perturbation current is applied in an optimized way. Finally the rich physics options of the DED are discussed.
