Announcement and Call for Papers
A. BACKGROUND
X-ray spectrometry (XRS) techniques have an instrumental role amongst available analytical tools required for an advanced characterization not only of modern technological but also of Cultural Heritage related materials. The capabilities of X-ray spectrometry techniques fulfil a broad range of requirements related to the type of analytical information (elemental, chemical, structural, dynamic and crystalline), the spatial resolution/range of analysis (from few tens of nanometre to macro-areas, ~m2), and the capability to overcome limitations commonly imposed by the sample physicochemical state (liquid, frozen or heated samples state analysis) and/or analysis environment (atmospheric pressure, anaerobic conditions, field/in-situ measurements, etc.). Summarizing the progress from early 1970s up to modern times, the various developments in the analytical performance and utilization of XRS techniques for interdisciplinary applications have been always motivated and driven by advances in relevant X-ray instrumentation (sources, detectors, x-rays focusing devices) and from the analytical requirements to provide a more integrated characterization of complex and 3D heterogeneous materials. For example, with the introduction of liquid nitrogen cooled semiconductor detectors (Si(Li), Ge(Li)), the X-ray Fluorescence (XRF) analysis was gradually established as an excellent analytical technique for the quantitative elemental analysis of a great variety of samples. Later on, in mid-1990s the components miniaturization and detector’s thermoelectrical cooling allowed the portability of the related instruments and thus paved the way for field analyses and planetary explorations. Most notably, with the worldwide installation and operation of plenty synchrotron radiation facilities, a plethora of XRS techniques and applications has been developed taking advantage of their unique and unprecedented properties.
The trend in X-ray spectrometry over the last few years is the development of larger area X-ray detection systems having higher throughput and being customized for the given type of application. Silicon drift detectors (SDDs) represent the best choice for high resolution, large dynamic range and high-speed detection of X-rays up to 20 keV energy when coupled with latest technology read-out electronics; large arrays of small area SDDs can now offer megapixel elemental maps in few hours supported by novel data acquisition and analysis strategy. For large area detection of hard X-rays (>40KeV), cadmium telluride (Cd-Te) based sensor arrays have been also developed and tested for various purposes including security and medical applications. The detection systems made by large arrays of sensors are used to improve considerably the throughput in laboratory and especially synchrotron radiation based experiments employing micro- or nano-focused excitation X-ray beams. In this field considerable progress has been attained using new generation polycapillary X-ray lenses (with few tens of micrometre spatial resolution) or more efficient optics devices such as Kirkpatrick-Baez mirrors, Fresnel zone plates, multilayer Laue lenses (MLLs) or compound refractive lenses (CRLs) which are able to focus X-ray beams close to the diffraction limit, in the region of few tens of nm. A different, but emerging, methodology called Full-Field X-ray Fluorescence Analysis offers micrometer spatial resolution by using novel pixelated X-ray detectors combined with pinhole geometry or sophisticated polycapillary structures. Among the pixelated detectors a particular generation of charge-coupled devices (CCDs) called pnCCDs offers energy and position resolution at a high quantum efficiency from the near infrared up to 20 keV with a high frame rate collection (~ 400 Hz).
Beyond the solid-state energy dispersive detection systems, High Resolution (HR) X-ray spectrometry supports a wide range of applications related to the materials science, (bio)chemistry, solid state physics (study of phase transitions in particular), physical chemistry as well as fundamental atomic and molecular physics studies. Cryogenic detectors such as Super Tunnel Junctions (STJ), Micro-bolometers or transition edge sensors (TES), and Bragg optics based spectrometers using bent analyzers offer certain advantages and disadvantages. For example, a resolving power of 10000 is aimed and 1000 can be attained in the soft X-ray region, whereas in the mid-energy regime, crystals are the best dispersive elements providing a resolving power even better than 10000. Moreover, crystal-based HR spectrometers in conjunction with position sensitive detectors offer high resolution (~.5 eV @ 5keV) time-resolved one-shot experiments at X-ray FEL facilities.
In this landscape of X-ray instrumentation developments and analytical performance merits, the trend is that various techniques and methodologies are integrated in the same set-up and are exploited in new applications. Grazing incidence XRF (GIXRF) analysis in combination with X-ray reflectometry (XRR) and absorption techniques are developed for the characterization of heterogeneous micro- and nano-scaled materials (for energy storage and conversion: batteries, fuel cells, photovoltaics, among other applications), 3D confocal set-ups in combination with X-ray transmission micro-tomography (CT) and X-ray fluorescence micro-tomography (XRF-CT) investigate 3D elemental distribution and structure of a broad range of 3D heterogeneous materials or of single microscopic inclusions with importance in biology, biomedicine, geology and cultural heritage. Modern HR techniques such as X-ray Emission Spectroscopy (XES), Resonance Inelastic X-ray Scattering (RIXS) and X-ray Raman Scattering provide unique information related to the local electronic structure, the chemical environment, bonding to the ligands, delocalization of valence electrons in modern materials or in the surface/interface related science.
