Tutorials

Step into the future of scientific discovery with our immersive training designed to help you harness ESRF’s powerful computing and data management environment — all in the spirit of Open Science.

Part 1: Foundations of Open Science and ESRF’s Digital Ecosystem, including the key platforms that enable easy data sharing, reproducible workflows, and efficient collaboration across teams

Part 2: Hands-On Deep Dive for Power Users, an interactive session where you’ll work with your own preferred software or tools on ESRF’s infrastructure (VISA, Jupyter, SLUM, etc.). Dive into job scheduling, advanced data workflows, and optimize your research pipeline with expert guidance from beamline scientists and IT experts.

Disorder is the hallmark of a large variety of systems where fluctuations play the major role in determining and characterizing the (dynamical) properties of the system.
Temporal (electron) density fluctuations are traced by the intermediate scattering function f(Q,t), where Q is the scattering vector or momentum transfer, giving the full description of the dynamics of condensed matter at the microscopic level in the Fourier space. Accessing the f(Q,t) either experimentally or in simulations is of fundamental importance for a whole category of disordered systems like glasses, since the dramatic freezing of the time fluctuations from the super-cooled liquid state is the main structural signature of the glass transition.
Density fluctuations can be measured by coherent light in a scattering experiment where the speckle pattern becomes resolved in the detector. Speckles are ensembles of fine interferences generated by disorder encoding the instantaneous exact structural arrangement of the specimen. They are modulated in space by the size of the coherent probe and in time by the sample fluctuations characterizing its dynamics.
Thanks to the high brilliance of the 4th generation synchrotron sources like the Extremely Brilliant Source (EBS) at the ESRF, X-ray scattering with coherent X-rays can be exploited to measure the f(Q,t) in a larger variety of systems not accessible by visible light (e.g. opaque) over a wider range of length scales from the meso-scale at small Q to the atomic scale at large Q.
X-ray Photon Correlation Spectroscopy (XPCS) is the actual experimental technique that measures the intermediate scattering function. XPCS retrieves the f(Q,t) by quantifying the temporal correlation of the intensity fluctuations in speckle patterns arising from the electronic density fluctuations. Spontaneous and driven dynamics can be retrieved in the temporal domain down to 10-6 s in a large variety of soft and hard condensed matter systems, e.g. colloids, gels and phase-ordering alloys at the meso-scale, deeply super-cooled melts and structural glasses at the atomic scale.
The tutorial covers the fundamental principles of XPCS based on coherent X-ray scattering and details of the data collection. Special emphasis is put on the data analysis practice and interpretation of the results. Finally, we show the large impact of EBS, allowing the extension of XPCS towards faster time scales down to 10 ns and high energies above 20 keV allowing high-pressure studies in diamond anvil cells.

Instructions/Information

Please bring your own laptop and if you wish your own data for analysis.

This is a hands-on tutorial for the analysis and interpretation of data recorded at ID01 by Scanning X-ray Diffraction Microscopy (5D-SXDM). First, the SXDM technique and the beamline will be introduced. Then, the users will be guided through a workflow starting from raw beamline data and arriving at spatially resolved strain maps for a recent use case, utilizing both the python packages and the X-ray Strain Orientation Software (X-SOCS). Lastly, the physical meaning of micro-strain observed by SXDM will be discussed, and different capabilities of the technique will be outlined.
