Chemical Sputtering and Radiation Enhanced Sublimation of Carbon

Abstract

The particularities of graphite sputtering at elevated temperatures are presented. Chemical sputtering, i.e. volatile molecule formation with hydrogen isotopes is extensively studied at energies above 100 eV and at thermal energies. Data on radiation enhanced sublimation of carbon are still scarce and available only for ion energies above 100 eV. The current understanding of both processes is summarized and an attempt is made to quantify erosion yields for fusion relevant conditions.
