8. Use of Coherence Methods in X-ray Powder Diffraction

Multibend Achromat Upgrades are being developed at a number of Synchrotron Radiation facilities, including ALBA. By greatly reducing the beam emittance, the coherent fraction of the X-rays produced by the undulators is correspondingly increased. The “diffraction limit” is reached where all X-rays up to a certain energy cutoff are fully coherent. This energy is expected to move into the hard...

9. Exploiting brilliance at cSAXS, the small-angle X-ray scattering beamline at the Swiss Light Source

Located at about 1 hour from Zurich, the Swiss Light Source is a 3rd generation synchrotron quite comparable in size with Alba. The coherent small-angle X-ray scattering (cSAXS) beamline exploits the brilliance of its undulator source to perform experiments such as scanning SAXS, in which the beam is focused to a spot of about 10 microns and the specimen is raster scanned. By collecting SAXS...

10. Time resolved computed tomography/tomoscopy

Time-resolved in-situ and operando tomography is increasingly moving into the focus of materials research. Improvements in time and spatial resolution will be presented, which allow for an analysis of fast phenomena and detailed 3D process imaging. We apply real-time in-situ tomography with acquisitions rates of up to 1000 tomograms per second, which we call “tomoscopy”. The sample environment...

11. Probing structure development during “in-operando” processes by time resolved simultaneous Small and Wide Angle X-ray Scattering with synchrotron radiation

Since the earliest application of synchrotron radiation to the investigation of soft condensed matter it became clear that time resolved Small Angle X-ray Scattering (SAXS) experiments enabled plenty of opportunities for precise “in-situ” structural characterization[1-3]. The simultaneous use of Wide Angle X-ray Scattering with SAXS (SAXS/WAXS) paved the way for an extensive plethora of...

12. Complex Systems and Coherent X-rays: A perfect match

Beatrice Ruta

X-ray Photon Correlation Spectroscopy (XPCS) is a spatio-temporal coherent X-ray scattering technique that probes slow collective dynamics at the nanometric and atomic scale based on the ob-servation of fluctuating far-field speckle patterns [1].
This technique has been successfully applied to the investigation of the slow relaxation processes occurring in disordered materials undergoing...

13. Quantitative and chemical nanoimaging of heterogeneous materials by 3D X-ray ptychography

Julio César da Silva

The properties of functional composite materials are heavily a↵ected by the arrangement of the different material phases within their 3D structure. The ability of visualizing their structures with high sensitivity and nanometric spatial resolution can improve the engi- neering of these composites. Ptychography is coherent X-ray imaging technique that has revolutionized this type of...
