The SAXSLab Ganesha system is a point collimated pinhole system with a 2D configurable detector that allows for X-Ray scattering studies of isotropic and non-isotropic liquid and solid samples in SAXS, MAXS, WAXS, and GI-SAXS modes.
Small Angle X-Ray Scattering (SAXS) is an analytical method for nano-structure analysis. When X-Rays penetrate the sample in the SAXS system, they are scattered by the nano-structures within the sample at small angles, since these structures are large compared to the X-Ray's wavelength. The resulting scattering patterns are characteristic of the nano-structure's size, shape, and internal structure. Wide Angle and Mid Angle X-ray Scattering (WAXS & MAXS) are also methods employable on the Ganesha for measuring q-ranges larger than detectable using a SAXS configuration. Grazing Incidence SAXS & WAXS (GI-SAXS & GI-WAXS) utilizes the reflection and refraction patters of produced when an incident x-ray beam interacts with the outer most layer (~10Å) of a sample surface to give insight into the sample's surface typography and repeating structures.
