In the Kyoto University Research Reactor Institute, the development of a nuclear-reactor-based slow-positron beamline and its application have been studied. Positron is the antiparitle of electron and it has some specific properties. The beamline is the apparatus for positron annihilation spectroscopy which is a powerful tool to investigate vacancy-type defects or voids of materials. Now, we’re developing a brightness enhancement section to reduce beam sizes for measurement. In this presentation, we will show the outline of the beamline and current status of development.
