X-ray Techniques for Materials Research - From Laboratory Sources to Free Electron Lasers
| - |
In Nice
Scope:
Great progress is currently being made in the application of X-ray methods to materials science due to an improved control of the space-time structure of the probing X-ray photons and the development of sophisticated experimental set-ups and data analysis schemes. Ever decreasing small areas like single grains from a polycrystal sample may be investigated by beam sizes in the µm range and below. Also studies on thin film growth, chemical reaction kinetics and other dynamical processes have become possible thanks to the availability of time-resolved radiation facilities. Great progress in source characteristics and X-ray instrumentation has enabled a new level in the quality of research.Materials microstructure: X-ray diffraction and subsequent line profile analysis is the only non-destructive technique giving estimates of crystallite size, size distribution function, defects and microstrains; these all have a large impact on materials functionality. Moreover, X-ray diffraction has become one of the most powerful tools to study the structural properties of nanocomposites, which nowadays receive a great interest for their numerous potential applications.
Texture and residual stress both introduce pronounced anisotropy in the properties of polycrystals. The physical causes for these phenomena are intensively under discussion in the community and offer a pathway to improve our understanding of materials processing.
The availability of micron and sub-micron beams makes possible micro-diffraction and nano-spectroscopy with unprecedented resolution, which is important in nano and surface science as well as in many industrial and environmental issues. Furthermore, such small beams allow one to probe very small sample volumes under extreme conditions of pressure and temperature.
The coherence of synchrotron X-ray beams enables use of phase sensitive techniques. Phase imaging is providing new insight in structures which have limited, or similar, absorption contrast. The development of fast 3D imaging techniques with synchrotron radiation allows real time experiments for example in the field of metal solidification. Diffraction based imaging gives access to 3D crystallographic arrangements of grains in undeformed materials opening vast avenues of research.
Established techniques such as photoemission, absorption and diffraction are taking advantage of the properties of advanced synchrotron radiation sources by improving resolution and detection limits (e.g. in fluorescence X-ray absorption or trace element analysis applied to impurities, defects and dopants or surfaces).
X-ray Free Electron Laser sources are currently in construction in a number of laboratories world-wide. These sources will provide unprecedented possibilities in x-ray science and this symposium aims at discussing their application to materials science.
The proceedings of the symposium will be published in a special issue of Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms by Elsevier.

XTOP 2014. 12th Biennial Conference on High-Resolution X-Ray Diffraction and Imaging
| - |
In Grenoble and Villard-de-Lans
History and scope
The first XTOP conference ("X-ray Topography and High Resolution Diffraction") took place in Marseille in 1992. The original topics covered were topography, double- and triple-crystal diffractometry of epitaxial layers, reflectometry and standing waves technique, with other added at later meetings. Topics for XTOP '2014 hold to the traditions of all the previous conferences.
XTOP brings together scientists from the fields of X-ray diffractometry, reflectometry, standing waves, coherent and conventional X-ray diffraction imaging and topography, as well as X-ray phase contrast imaging (radiography and micro-tomography). XTOP is thus one of the central scientific conference concerning methods and instrumentation in synchrotron-based high-resolution X-ray diffraction methods, phase contrast imaging, and micro-tomography.
Previous XTOP conferences:
- 1992: Marseille (France)
- 1994: Berlin (Germany)
- 1996: Erice (Italy)
- 1998: Durham (United Kingdom)

Science@FELs 2014. 2nd international Science at FELs Conference
| - |
In PSI Villigen
The Collaboration of European FELs and SPS Facilities announces the Science@FELs 2014.
The 2nd international Science at FELs Conference, organized by the Paul Scherrer Institute, will take place in the Auditorium of the Paul Scherrer Institute in Villigen, Switzerland.
This conference is a follow up of the Science@FELs 2012 jointly organized by DESY and the European XFEL in Hamburg, Germany, in July 2012 and will henceforth be organized regularly as an activity of the Collaboration of European FEL and SPS Facilities.
Science@FELs 2014 will focus on the scientific highlights achieved during the recent years in the fast evolving development and operation of free electron lasers. The scientific programme of the conference will consist of invited talks and contributed presentations, either in the form of oral presentations or posters.
The conference sessions will be held from Monday to Wednesday, with the Tuesday afternoon of the conference dedicated for a tour to PSI's large scale facilities and the SwissFEL construction site.

Emerging Photon Technologies for Chemical Dynamics - Faraday Discussion 171

Faraday Discussion 171: Emerging Photon Technologies for Chemical Dynamics
9 - 11 July 2014, Sheffield, UKIntroduction
Understanding the mechanism of physical, chemical and biological change at the microscopic scale is critical for a broad range of science and technology. A common goal is to develop this understanding to the point where it becomes possible to tailor functionality through material design, or by the application of electric, magnetic or optical fields. Across a broad range of disciplines the scientific community is currently frustrated by its inability to dynamically image matter down to the atomic scale. We can at present only observe relatively slow motion changes to structure, or infer dynamical effects via indirect measurements. Yet many critically important processes evolve on the femtosecond timescale and at the molecular and sub-cellular level requiring nanometre and sub-nanometre scale spatial resolution. The properties of light from newly developing photon sources such as free electron lasers (FELs) are dramatically different from those of storage rings (in terms of spectral brightness), and from conventional lasers (in terms of wavelength range). In the course of the last few years FELs and other sources have emerged as exceptionally exciting tools for new science. For example, new results from FLASH (Hamburg) and LCLS (Stanford) are already revealing prospects for remarkable future impact which is expected to revolutionize our understanding of mechanisms in, for example, solution phase chemistry, enzyme and surface catalysis and DNA photo-induced radiation damage. Other machines in Germany (European XFEL), Italy, Japan, and Korea are progressing rapidly towards the first generation of light and UK physicists and chemists are starting to establish a strong presence at these facilities.Aims
It is timely to hold a Faraday Discussion which focuses on the potential impact in chemistry. Because the subject by its very nature is highly inter-disciplinary we anticipate strong participation from physicists as well as chemists. Indeed, many of the initial studies have focused on atoms, rather than molecules, but the techniques used are directly transferable.Format
The Faraday Division have been organising high impact Faraday Discussions in rapidly developing areas of physical chemistry and its interfaces with other scientific disciplines for over 100 years. Faraday Discussions have a special format where research papers written by the speakers are distributed to all participants before the meeting, and most of the meeting is devoted to discussing the papers. Everyone contributes to the discussion - including presenting their own relevant research. The research papers and a record of the discussion are published in the journal Faraday Discussions.Themes
- Â Chemical reaction dynamics
- Â Electron dynamics in atoms, molecules and clusters
- Â Correlated systems, surfaces and catalysis
