摘要：

Ergodic divertor (ED) experiments in helium plasmas with carbonized and boronized wall conditions have been performed in Tore Supra. The intrinsic impurity decontamination effect (as well as the screening of purposely injected nitrogen impurities), previously observed in deuterium plasmas, has been confirmed also for conditions where the electron density in the confined (unperturbed) bulk plasma remains practically constant. Inward displacements of the plasma 0.10-0.15 m away from the ED modules result in the magnetic perturbation having little or no effect on impurities.
