The McMaster Analytical X-Ray Diffraction Facility (MAX) is a service, research, and teaching laboratory operated by the Department of Chemistry and Chemical Biology and the Brockhouse Institute for Materials Research. It is a leader in materials characterization by x-ray diffraction in Canada. The most unique feature of MAX is the regular use of visualization of experimental 3-dimensional diffraction patterns from single crystals, nanocrystal thin films, or polycrystalline solids using technology developed at McMaster. This capability vastly improves our ability to identify and interpret the structural and orientational features of the materials being studied. It has enabled us to contribute internationally to the development of texture analysis of materials and to reciprocal space mapping techniques.
