Electrons! High speeds! Intense beams of light! Claire Concannon takes a tour of our nearest particle accelerator – the Australian Synchrotron in Melbourne. Designed to create high-energy x-ray light useful for science, the synchrotron enables an incredible diversity of research. And, because of long-standing funding support, New Zealand scientists can also use it. Claire finds out what interesting research questions some visiting New Zealanders are shining a light on.
