The Materials Cluster is a multi-function and multi-purpose Research Support Facility providing a wide spectrum of services and apparatus for materials testing, preparation, and characterization. The Cluster also provides tools that can generate images of surface or near-surface characteristics, such as topography or electronic structure, at length scales from microns down to nanometers in environments ranging from ultra-high vacuum to fluids. The CCMR facilities are run by expert staff who provide training and technical assistance. We welcome outside users from both industry and academia.
