ABSTRACT

The unprecedented coherent flux of 4th-generation synchrotron sources demands equally advanced detection and data analysis tools. DECTRIS addresses this challenge with high-speed, noise-free photon-counting detectors — PILATUS4...

20. Coherent DiffractionImaging at the CRISTAL beamline

Poster

CRISTAL is a hard X-ray diffraction beamline dedicated to the study of the structural properties of matter at different length scales, ranging from sub angstromic to millimetric lengthes, possibly in non-ambient conditions.

Coherent Diffraction Imaging in Bragg conditions (BCDI) is one of the techniques proposed to the users among a large panel. A dedicated setup displayed on Figure 1 is...

19. Implementation of Ptychography Workflow at the HERMES Beamline

Poster

Since 2019 HERMES beamline [1] implemented and is continuously optimizing a dedicated setup to perform ptychography experiments and such push the spatial resolution limit beyond the present Fresnel zone plates limitations, i.e. 30 nm. Here we present the mechanical, optical, hardware and software integration of the setup in the STXM instrument, along with the functional workflow from a user...

9. PUSHING THE LIMITS OF EELS WITH THE NEW ILIAD EELS SPECTROMETER

Poster

Electron energy-loss spectroscopy (EELS) in a transmission electron microscope (TEM) is an exceptionally versatile technique that goes far beyond its well-known application in elemental analysis. Analogous to X-ray absorption spectroscopy (XAS) at synchrotron facilities, EELS is based on the ionization of core electrons and provides similar information, while offering the significant advantage...

24. Soft x-ray coherent scattering for magnetic studies at the Sextants beamline

Poster

Many current forthcoming applications of magnetic materials involve heterostructures or alloys containing magnetic and non-magnetic elements. X-ray Resonant (Coherent) Scattering is the technique of choice to probe such phenomena thanks to its element-selectivity and spatial sensitivity.
In this poster I will introduce the experimental set-up that we developed at SOLEIL and illustrate their...

23. Synchrotron-based studies of self-assembled biogenic photonic crystals

Poster

Colors in animals can be produced either chemically by pigments or physically by the constructive interference of light scattered by photonic nanostructures and sometimes as a combination. Fade-proof, saturated structural colors have evolved convergently in diverse animal taxa, including birds1,3, insects and spiders2,4. However, given that the underlying nanostructures are overwhelmingly...
