MASSIF-1 has led the charge in fully automated data collection from cryo-cooled samples and is now branching out to automate in situ and plate to beam experiments. This tutorial will detail the new in plate and CrystalDirect Harvester capabilities on MASSIF-1 and will demonstrate how to get the best out of these new experiments. From in situ data collection from very fragile samples to high throughput ambient temperature data collection and fragment screening we will explain how to get the best out of this new level of automation in MX.

Introduction to the basic principles and concepts of (volume) image analysis followed by practicals. Software packages and methods will be presented.

Your research is finally out? Congratulations! Now, let’s not forget that the research publication is not the end of the process but the beginning of another important one: communication. Mastering communication and all communication tools, especially social media, is now crucial to promote your research. Scientists themselves are embracing more and more roles that were conventionally taken on by trained science communicators.

So how do you stand out from the huge flow of communication generated on social media? How do you engage with your audience? Let’s talk about science, communication and social media.

SCOPE

Introduction to pyFAI with emphasis on recent developments (statistical analysis in rings, outlier rejection ...)
* Calibration of an experimental setup, hands-on SAXS and WAXS examples
* Data-reduction for mapping or XRD-CT experiments
* Peak-finding for raster-scanning experiment and application to crystal-centering.

This tutorial provides an introduction on how to carry out a quantitative analysis for XAS data. A first part will be devoted to data reduction on the beamline and a second part on strategies of data fitting. Single shell and multishell analyses will be presented using the DEMETER (https://bruceravel.github.io/demeter/) program suite.

SCOPE

After a short introduction on XANES, X-ray Raman, and valence-to-core X-ray Emission spectroscopy, and the specificities of FDMNES, most of the tutorial will be devoted to:
   * Learn the basic use of fdmnes
   * Make a series of numerical experiments to see the sensitivity of the spectroscopies to the material geometry and the beam polarization
   * Study specific cases with participants

Coherent X-rays are a unique tool to access dynamics in condensed matter at the length scale probed by the scattering vector Q. This is achieved by quantifying the temporal correlation of the intensity fluctuations in a speckle patterns. Spontaneous and driven dynamics can be retrieved in the temporal domain down to 10-6 s in a large variety of soft and hard matter systems, e.g. from the meso-scale in colloids, gels and phase-ordering alloys, down to the atomic length scale in deeply super-cooled melts and structural glasses.
The tutorial covers the fundamental principles of the coherence-based technique and details of the data collection. Special emphasis is put on the data analysis practice and interpretation of the results. Finally, we will show the first results with the increased brilliance and coherence at ID10 with the ESRF-EBS, enabling new exciting scientific prospects in the field.
