NanoFab Tool: Rigaku SmartLab X-Ray Diffraction
The Rigaku SmartLab X-ray diffraction system (XRD) is a fully automated, modular system for advanced x-ray diffraction measurements on a wide range of materials including thin films and powders. The system uses a high power, 9 kW rotating anode X ray generator which allows faster collection times with less background noise and is optimized for advanced thin film measurements. This XRD system can be used to determine the crystal structure and identify the phases of thin films and bulk materials. The SmartLab is easy to use and is fully equipped with modules for performing a variety of advanced X ray diffraction measurements such as X ray reflectivity, grazing incidence diffraction, reciprocal space maps, rocking curves, and small angle X ray scattering (SAXS). The SmartLab Guidance software guides the user through alignments and experimental setups, making the system very easy to use.
