During this talk I will present the opportunities for structural characterization of materials at the Brockhouse beamlines at the Canadian Light Source.
The Canadian Light Source has three new hard x-ray beamlines dedicated to diffraction and scattering for materials science. The beamlines have been operation for the past 2 years and have several end-stations covering a wide range of structural characterization techniques. The broad energy range from 5 to 95 keV allows to select the ideal energy for many different techniques, including high resolution x-ray diffraction, small angle x-ray scattering / reflectivity, high energy x-ray diffraction (going through real life samples and environments), total scattering measurements for Pair Distribution Function (PDF) analysis, reciprocal space maps and grazing incidence diffraction. Anomalous and magnetic scattering experiments with element sensitivity are also possible by tuning the beam energy close to an absorption edge. These techniques yield a broad range of structural information from near, medium and long-range order in the sample, giving insight into the structure-property relationship.
We welcome a large number of users in our beamlines, many of them coming to perform in-situ experiments in areas such as catalysis, mineralogy, environment, food science, semiconductors, batteries, alloys, polymers, solar cells, among others. As a Canadian open access research facility, we support our users to enable great science!
Bio:
Beatriz got her B.S and Masters degrees in Havana, Cuba. She finished her Ph.D and post-doc in the National Institute for Space Research in Sao Paulo, Brazil. During this time, she was a frequent user of the Brazilian Light Source diffraction beamlines, where she then worked as a staff scientist. In 2012 she started working at the Canadian Light Source, in the Brockhouse project. Her research interests include applying a variety of synchrotron techniques to solve structural problems in thin films, multilayers, quantum dots, magnetic heterostructures, catalysts, among other materials.
