Positron annihilation lifetime spectroscopy serves as an excellent tool for studies of open-volume defects in solid materials such as vacancies, vacancy agglomerates, dislocations, pores and voids. The intense mono-energetic positros beamline (MePS) at the ELBE accelerator developed for positron life-time and conventional Doppler Broadening experiments offers a non-destructive investigation method to study of porous media as well as thin film as a function of thickness.
