The Bragg Institute is a neutron and X-ray scattering group in Australia. It is part of the Australian Nuclear Science and Technology Organisation's (ANSTO) site outside Sydney, in New South Wales, Australia. The Institute was named as a tribute to the father-and-son team Sir William Henry Bragg and son William Lawrence Bragg, who were jointly awarded the Nobel Prize for Physics in 1915 for pioneering the analysis of crystal structures by means of X-rays.
The Institute was formed in December 2002, in preparation for the start-up of the Open-pool Australian lightwater reactor in 2006. The Institute operates the user facility associated with OPAL, including 10 operational neutron beam instruments, and 3 more currently in commissioning. It is also home to the National Deuteration Facility, which runs a user service providing both bio-synthesis and bottom-up organic synthesis of molecules for use in neutron scattering, triple-labelled NMR, and other studies, and operates two small-angle X-ray scattering instruments and an X-ray reflectometer.
The Institute's main research themes are in food science, energy materials, magnetism, cultural heritage and engineering materials.
The Institute has been led since its inception by Robert Robinson, and employs approximately 100 staff.
