16th XTOP Biennial Conference on High-Resolution X-Ray Diffraction and Imaging
-
In Karlsruhe
The first XTOP conference was held in Marseille in 1992. With an initial focus on X-ray topography andhigh-resolution X-ray diffraction, the conference has always combined aspects of X-ray scattering and X-ray imaging. Over time, other related topics such as X-ray phase-contrast imaging, tomography and microscopy, and various scanning X-ray imaging techniques have been added.
Today, XTOP brings together scientists working on X-ray diffraction, reflection, grazing-incidence scattering, standing-waves, coherent diffraction, and ptychography techniques, as well as X-ray microtomography, microscopy and other imaging techniques based on phase, diffraction, scattering, or spectroscopic contrasts.
XTOP is a leading scientific conference on instrumentation, methods, and applications of laboratory and synchrotron-based X-ray diffraction and imaging techniques.

School and Conference on Analysis of Diffraction Data in Real Space
-
In Grenoble
The ADD2026 School and Conference aim to deepen the understanding and to further the training of the various communities working with real-space data analysis methods in neutron and x-ray diffraction. The Fourier transformation of total-scattering diffraction data from reciprocal space into real space produces a Pair-Distribution Function (PDF) that represents a model-independent "snapshot" of the short-range atomic structure within the sample. The PDF(r) thus probes both static and dynamic local atomic correlations (as well as local magnetic spin correlations in the case of neutron diffraction). The measured PDF(r) can then be modelled or simulated using various software packages. These so-called "PDF-analysis" methods are therefore complementary to the well-known Rietveld method of refining diffraction data in Q-space that however provides only a space-time averaged picture of the sample's structure.

35 European Crystallographic Meeting
|
In PoznaÃ...„
 At the XXV Congress and General Assembly of the International Union of Crystallography in Prague, it was decided that the 35th edition of the European Crystallographic Meeting would be held in Lviv, Ukraine, in 2025.
 Unfortunately, there is a war in Ukraine, and it is not reasonable to organize a great scientific event in Lviv in 2025. An alternative was thus elaborated where, thanks to a collaboration between the Ukrainian Crystallographic Committee and the Polish Crystallographic Association, the conference site will be Poznan, a city in neighbouring Poland.
Synclight 2024 - São Paulo School of Advanced Science on 4th Generation Synchrotron Techniques
|
In Campinas
Promoted by CNPEM and funded by São Paulo Research Foundation (FAPESP), SyncLight 2024 aims to gather young researchers from Brazil and around the world to discuss the recent opportunities offered by advanced experimental synchrotron techniques available at Sirius, the Brazilian 4th generation light source.
Over the past decades, synchrotron light sources have played a significant role in the development of modern natural sciences and engineering. With a wide range of experimental techniques available, synchrotron light sources have revolutionized the way scientists study and characterize materials in the fields of Physics, Chemistry, Biology, Health, Energy, New Materials, Environmental Sciences, and many others.
The interdisciplinary nature of the event, combined with the collaboration of the LNLS User Committee, which includes researchers from various institutions across Brazil, will contribute to the exchange of experiences among young researchers, professors, and experienced researchers. The event's program includes lectures, poster sessions, and guided tours at the facilities will also be organized. Tutorials on experiments conducted, demonstrations on the control of the accelerators, as well as data analysis and simulations taught by LNLS researchers, at the laboratory's beamlines, are also planned.
The theme is particularly relevant to the Brazilian scientific scenario, as Sirius is one of the most modern and brilliant synchrotron light sources in the world. Currently, ten beamlines are open to the scientific and technological community, out of a set of 14 initially planned to cover a wide range of scientific programs. One of the objectives of SyncLight 2024 is precisely to assist in the training and formation of a new generation of user-researchers, capable of benefiting from this large scientific infrastructure in operation in Brazil.
SyncLight 2024 is part of the São Paulo School of Advanced Science (SPSAS) modality, funded by FAPESP, which provides resources to promote short courses in different areas of knowledge in the State of São Paulo.
