Accelerator-based ion beam analysis (IBA) techniques and capabilities can be applied across a range of imvestigations.
Some recent research includes monitoring ambient air pollution at sites across Australia and Asia known as the aerosol sampling program (ASP), determining heavy metal pollutants in biological systems, studying the composition of archaeological artifacts and soil specimens, analysing thin films for photovoltaic (solar cell) applications, and probing materials engineering problems such as corrosion and coating delamination. A range of ASP publications is available online.

Partners and collaborators
The IBA facilities are offered to 37 universities through AINSE and members of the group are involved in significant research projects that impact Australia and the wider global community. The IBA has partnerships with several environmental protection agencies, the Australian Coal Association, private industry, the CSIRO and International Atomic Energy Agency in Vienna (IAEA), among others.
Australian and international researchers and industry can request access to IBA facilities through ANSTO's Research Portal for users.
