Tutorials

Scope

At this year BAG meeting, the morning presentations will focus on the latest software developments and especially on DRAC: the new ISPyB. This will be followed by an open discussion to collect feedback on the user experience.

In the afternoon, you will be able to directly exchange with the Structural Biology group staff during a “meet the scientists” session. This will be followed by a tutorial on ID29 and a tour of the structural biology labs and beamlines.

SCOPE

This session will introduce users to the recommendations of the European Synchrotron and FEL User Organisation (ESUO) on Open Science and Open Data and how to apply these to data taken at the ESRF. The session will present and explain the principles of Open Science and why they must be adopted. The session will include practical demonstrations of how to cite data correctly in publications and in different domain databases like the PDB, COD, NOMAD, etc. The session will conclude with a discussion on the roles of the ESRF and Scientists and what challenges Users still face in adopting Open Science.

SCOPE

• This hands-on tutorial will introduce the capabilities of the new Nuclear Resonance beamline (ID14) at the ESRF with a special emphasis given on Mössbauer spectroscopy with the synchrotron Mössbauer source (SMS) at the nanoscale.

•  An introduction to data evaluation software and instructions on how to conduct an experiment at the beamline will be given.

A couple of test measurements in transmission geometry (57^Fe, sub-micron focused beam size in diameter) will be done during the tutorial. Interested users may contact the organizers to arrange for the test measurement. 

SCOPE

This is a hands-on tutorial for the analysis and interpretation of data recorded at ID01 by five-dimensional 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 the SXDM Python package 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.

SCOPE

This tutorial aims to give participants the bases for carrying out in autonomy a complete XAS experiment at the LISA beamline. As a first step, we will briefly recall the bases of XAS theory and data analysis. Then, we will introduce the principles and practical aspects of sample preparation and spectra will be collected at the beamline on the samples prepared by the participants. Finally, a complete quantitative analysis will be carried out on the collected spectra.

It is recommended that participants come with their laptops with the XAS data analysis codes installed. It could be either:

DEMETER ( https://bruceravel.github.io/demeter/ )  or

LARCH ( https://xraypy.github.io/xraylarch/ )
