dc.description.abstractThe ARC-funded Centre for Antimatter-Matter Studies (CAMS) has been running since 2006 and one of its aims is the study of open volume defects in solid materials. The slow positron beamline constructed at the ANU can interrogate microns-thick films and surface layers and observe nano- and mesopores by the lifetime spectra of the positrons implanted into these layers. In addition, the CAMS project has a number of laboratory, or “desktop”, PALS Spectrometers that can detect open volume defects in bulk materials. These defects include cation vacancies in insulating solids (but not anionic vacancies), single vacancies and vacancy complexes in metal alloys, radiation-induced defects and general nano- and mesoporosity and defects, as well as phase separation in polymers. Examples will be given of the application of positron annihilation lifetime spectroscopy to various materials, notably pores in natural zircons, cation vacancies in oxides and silicates, and alteration layers on leached candidate glasses for radioactive waste immobilisation.en_AU
