The main aspects for the selection of plasma facing materials for ITER are the requirements of plasma performance (minimize impurity contamination), engineering integrity, component lifetime and safety (e.g., minimize tritium and radioactive dust inventories) [7]. Currently, the ITER design uses beryl-... 

J. Roth Review and Status of Physical Sputtering and Chemical Erosion of Plasma Facing Materials. In this volume... 

The review of different erosion processes reveals considerable progress, both in experimental investigation and understanding, of physical sputtering and chemical erosion of plasma facing materials. The review leads to the identification of the following open questions and data needs ... 

In the material modification due to non-recycling ions in a hydrogen plasma the mobility of the constituents will modify the surface concentrations and influence the erosion of the substrate. These effects can only be investigated in a controlled way using dual ion beam experiments. Such a system is being commissioned at IPP and results for the interaction of different plasma facing materials are expected in the near future.
