Abstract

Tungsten coatings were exposed to He/D2 plasma in the linear plasma machine Pilot PSI. Different He contents were used in the plasma. The sample surface temperature and plasma ion energy were varied. Changes in the surface morphology were studied using scanning electron microscopy (SEM) and x-ray diffraction (XRD). SEM images revealed that compared with the unexposed samples, there were significant changes in the surface morphology. The structures formed were strongly dependent on the experimental conditions. XRD spectra showed that exposure to plasma leads to an increase in the crystallite size and to a decrease in the lattice parameter
