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.
