In the past decade we have seen very important developments in the field of accelerator based X-ray user facilities, with the advent of 4th generation synchrotron sources and MHz rate free electron lasers. The first hard X-ray free-electron laser, LCLS (US) became operational in 2009 and over the…
Read MoreHeterogeneous Catalysis is one of the key fields of physical sciences that is attracting attention of both fundamental and applied research. Use of X-rays is particularly important in the studies of catalytic phenomena due to non-destructive nature of analysis, high sensitivity to various physical…

Speaker: Ian Robinson, University College London and Brookhaven National Lab, USA. The webinar is part of the LINXS webinar series, CoWork…
Read MoreThe ID01 beamline is a diffraction microscope used to probe the structure of crystalline materials. The recent upgrade of the ESRF - The European Synchrotron to an extremely brilliant source (EBS) has increased the coherent flux available for experiments by a factor 28. Speaker: Steven Leake…
Read MoreThe imminent upgrade of the Advanced Photon Source at Argonne National Laboratory to a diffraction limited storage ring will revolutionize coherent imaging capabilities. To take maximum benefit of the new source, new beamlines and instruments are currently being designed. An instrument named Atomic…
Read MoreThree dimensional magnetic systems promise significant opportunities for applications, for example providing higher density devices and new functionality associated with complex topology and greater degrees of freedom [1,2]. For the experimental realisation of these new properties, appropriate…
Read MoreThis talk presents some key concepts of FEL operation, and highlights from the first years of FEL science: mostly in the field of condensed matter physics, but with a broad overview of other research fields as well. The goal is to give simple guidelines that will hopefully help to broaden the…
Read MoreThis webinar reviews table-top x-ray spectroscopy setups. Second, it focuses on the discussion of time-resolved table-top setups as developed at Chemical Physics in Lund. In the third part, the webinar extends the discussion on the proposal writing process with a more detailed section on how to…
Read MoreX-ray coherence-based imaging comprises several powerful techniques which allow investigations in the different scientific fields, including biology and life sciences. The non-crystalline nature of such samples can be explored by coherent diffractive imaging (CDI) and ptychography and cellular…
Read MoreRecent progress in 3D coherent x-ray diffraction imaging methods can enable high resolution structural imaging of nano-structured crystalline materials. In this talk, I discuss developments in Bragg coherent diffraction imaging (BCDI) and Bragg ptychography that aim to broaden the envelope of…
Read MoreIn this presentation, I will first review the principles of the Bragg ptychography approach, before detailing a selection of scientific results obtained with this novel crystalline microscopy. I will finally discuss some exciting perspectives opened by the advent of the fourth generation…
Read MoreThere has been much interest in topological defects of spontaneous polarization as templates for unique physical phenomena and in the design of electronic devices. Experimental investigations of the complex topologies of polarization have been limited to surface phenomena, which has restricted the…
Read MoreCoherent Diffraction Imaging in Bragg geometry is used to study crystalline samples to access, along with morphology, also information on strain fields, defects and other atomic -scale features. This webinar will focus on the following points..... * the basic concepts of the technique and data…
Read MoreFlocculants are usually polymeric molecules which cause the aggregation of particles in suspensions and will modify the sedimentation of particles. The gravitational field and the hydrodynamics of the aggregates result in a situation where larger aggregates sediment more quickly for less efficient…
Read MoreNeutrons are powerful probes for the study of biological samples as they are very sensitive to hydrogen(H)-rich materials and can discriminate between isotopes of the same element. Due to this property of neutrons, they can be used to observe hydrogen and it’s isotope, deuterium in materials. To…
Read MoreX-rays are excellent probes for studying many different types of matter ranging from biological macromolecules to porous rocks at resolutions far beyond what is possible using optical wavelengths. However, when it comes to imaging, X-rays have one glaring weakness: it’s very hard to make a good…
Read MoreVideo lecture on LINXS YouTube - watch the video at YouTube.com Speaker: Cinzia Giannini, National Research Council, Bari This webinar is part of LINXS webinar series, Let's Dive into the Atoms. The aim is to create a fundamental understanding of how you as a researcher can use x-rays and neutrons…
Read MoreThis webinar presents the fundamentals behind coherent X-ray imaging techniques that exploit the high-brilliance provided by X-ray free-electron lasers and diffraction-limited storage rings. For such purpose, we will introduce the fundaments of i) interactions of X-rays with matter, ii) coherence…
Read MoreThe efficient use of X-ray and neutron diffractometers is often hindered by complicated data analysis software that creates barriers to entry for novice users and may even reduce efficiency for advanced users. The talk presents easyDiffraction, a software developed to interface with a very wide…
