An increasing lack in neutron irradiation facilities has spurred a revived interest in using accelerator-based ion irradiation to study radiation effects in materials. One well-known issue within the ion beam community is that ion beam can cause carbon contamination on the surface of target materials. However the extent of this contamination has not been well characterized nor quantified for irradiation effects studies of candidate materials for nuclear core applications. Due to the high mobility of carbon in ferritic/martensitic steels and its importance as an alloying element, carbon contamination can potentially affect microstructural evolution during ion irradiation. In this study, the effectiveness and short-comings in determining carbon contamination using three common techniques, ToF-SIMS, APT and TEM, will be presented and discussed. The corresponding microstructural changes related to carbon contamination in ion irradiated F/M steels are also presented. In addition, several potential carbon contamination mitigation approaches and their effectiveness will be discussed.
