An apparatus for measuring X-Ray small- and wide angle scattering of solid materials and especially of molten metals with temperatures up to 1100 °C is described. Alloys of the eutectic system Al -Sn with tin-contents up to 30 At.-% are investigated. The influence of surface oxide layers on the scattered intensity is discussed. Correlation functions as well as the Guinier approximation yielded inhomogeneities with mean diameters up to 10 Å in the investigated melts. Therefore the dimensions of these so-called short range segregation zones correspond to those of the first coordination sphere

A new construction of a high temperature set-up for small angle X-ray scattering (SAXS) measurements on corrosive and volatile fluid systems is presented. The sample cell from single crystal sapphire is sealed with a special metal wire technique. The cell with the surrounding high temperature furnace is integrated in a homemade SAXS-spectrometer. This technique has been employed up to 1000°C for the example of SAXS-measurements on fluid K

A commercially available small-angle X-ray scattering (SAXS) NanoSTAR instrument (Bruker AXS) with a liquid-metal-jet source (Excillum) has been optimized for solution scattering and installed at iNANO at Aarhus University. The instrument (named HyperSAXS) employs long high-quality parabolic Montel multilayer optics (Incoatec) and a novel compact scatterless pinhole slit with Ge edges, which was designed and built at Aarhus University. The combination of the powerful source and optimized geometry gives an integrated X-ray intensity close to 109 photons s−1 for a standard range of scattering vector moduli q = 0.0098–0.425 Å−1, where q = (4πsinθ)/λ and λ is the Ga Kα wavelength of 1.34 Å. The high intensity of the instrument makes it possible to measure dilute samples of, for example, protein or surfactant with concentrations of 1 mg ml−1 in a few minutes. A flow-through cell, built at Aarhus University, in combination with an automated sample handler has been installed on the instrument. The sample handler is based on the commercial Gilson GX-271 injection system (Biolab), which also allows samples to be stored under thermostatted conditions. The sample handler inserts and removes samples, and also cleans and dries the sample cell between measurements. The minimum volume of the flow-through capillary is about 20 µl. The high intensity additionally allows time-resolved measurements to be performed with a temporal resolution of seconds. For this purpose a stopped-flow apparatus, (SFM-3000, Bio-Logic) was connected to the flow-through cell by high-performance liquid chromatography tubing. This configuration was chosen as it allows vacuum around the sample cell and thus maintains a low background. The instrument can readily be converted into a low-q setup with a q range of 0.0049–0.34 Å−1 and an X-ray intensity of about 5 × 107 photons s−1.
