Advances in storage technology for low energy positrons in the past 10 years have produced a wealth of new and exciting advances in
antimatter-matter interactions involving positrons and positronium. New generation buffer gas traps have enabled the storage, and cooling, of large numbers of positrons
which have been used for a range of experimental breakthroughs - from the production and storage of antihydrogen, to the formation of di-positronium.
This talk will outline these technological developments and the way in which we have used them at the ANU for studies of positron interactions with atoms, molecules and materials, and the potential applications of these studies in biomedical and materials science.
