Closer look at nuclear and accelerator techniques

ANSTO

In Part 2 of our series exploring the world of nuclear science and technology at ANSTO, we share more detailed information about the nuclear scientist’s toolkit.

Revealing the atomic-scale secrets of materials requires a variety of cutting-edge imaging and analytical instruments that use beams of different types of particles. Beams of x-rays, neutrons, and ions provide complementary information about various aspects of a material’s structure at the molecular and atomic levels. When combined, these techniques reveal insights that enable us to understand and ultimately control the properties of materials.

ANSTO today provides the research community with a suite of scientific user facilities-x-ray light sources, neutron sources, and ion accelerators – to explore the atomic world.

Our user facilities enable experimental studies that cannot be done in ordinary laboratories, and these facilities have created a new style of research in which scientists conduct investigations that benefit from a merging of ideas and techniques from different disciplines.

Together many thousands of researchers pursue investigations at ANSTO’s facilities that improve the economy, energy options, medical treatments, and technologies and improve our fundamental understanding of the materials that make up our world.

X-ray light sources

Atom-Sychrotron-Interaction

Millions of times brighter than the sun, light sources such as ANSTO’s Australian Synchrotron generate high-quality, stable beams of x-rays and other electromagnetic radiation that can be used for numerous experimental techniques.

Electrons are deflected as they travel past bending magnets along the circular track of a synchrotron or through other specially designed magnetic devices. This creates a continuous spectrum of radiation with various wavelengths and strengths (such as infrared light and hard or soft x-rays) that scientists select to suit their particular experiments.

These rays are then sent down beamlines to sophisticated instruments in work areas or end stations where studies are conducted.

Using synchrotron light to interact with the electrons in an atom, scientists reveal the structure, chemical composition, electronic properties, and other features that are critical to materials science, chemistry, archaeology, molecular electronics, and a host of other disciplines.
