Phase-space analysis of neutron optics has revealed that neutron imaging by Bragg reflection from thick bent perfect crystals can be non-dispersive (independent of the neutron wavelength), like with an optical mirror. The corresponding devices, called Bragg mirrors (BM), can be used for neutron imaging at pulsed neutron sources. Using a position sensitive detector (PSD) and time-of-flight analysis (TOF), a BM imaging system will make it possible to collect both real space mapping data and scattering space data simultaneously. Each pixel of PSD will correspond to a point in the sample and will contain a segment of the diffraction pattern (useful for strain, text ure or phase analysis), or of an inelastic spectrum. In this paper the resolution and efficiency of BM in TOF diffraction experiments are calculated and compared with the usual sequential method of mapping. Experimental tests performed at steady state neutron sources showed sub-millimeter spatial resolution in the onedimensional case.

“…Incident beam cross-sections less than 1 × 1 mm 2 can be achieved without sacrificing significant incident intensity using Kirkpatrick-Baez focusing mirrors. [56] For beam-sensitive samples, the balance between beam size and power density on the sample is an important consideration. For the diffracted beam, optics are chosen to improve the limited signal to background ratio in CTR measurements.…”

In crystalline materials, the presence of surfaces or interfaces gives rise to crystal truncation rods (CTRs) in their X‐ray diffraction patterns. While structural properties related to the bulk of a crystal are contained in the intensity and position of Bragg peaks in X‐ray diffraction, CTRs carry detailed information about the atomic structure at the interface. Developments in synchrotron X‐ray sources, instrumentation, and analysis procedures have made CTR measurements into extremely powerful tools to study atomic reconstructions and relaxations occurring in a wide variety of interfacial systems, with relevance to chemical and electronic functionalities. In this review, an overview of the use of CTRs in the study of atomic structure at interfaces is provided. The basic theory, measurement, and analysis of CTRs are covered and applications from the literature are highlighted. Illustrative examples include studies of complex oxide thin films and multilayers.

“…[5,8,[10][11] Synchrotron radiation X-ray fluorescence (SRXRF) spectroscopy, also known as synchrotron radiation induced X-ray emission (SRIXE) spectroscopy, has become competitive with the earlier microprobe and nanoprobe techniques following the development of X-ray focusing devices, such as the KirkpatrickBaez (KB) mirror and the zone plate, that are capable of micron and submicron resolution, respectively. [12][13][14][15] There are two important features that contribute to the superb elemental sensitivities of microprobe SRXRF: (i) the absence of the continuum (bremsstrahlung) background radiation that is a feature of spectra obtained from charged particle beams, and…”

Synchrotron radiation spectroscopic techniques as tools for the medicinal chemist: microprobe X-Ray fluorescence imaging, X-Ray absorption spectroscopy, and infrared microspectroscopy AbstractThis review updates the recent advances and applications of three prominent synchrotron radiation techniques, microprobe X-ray fluorescence spectroscopy/imaging, X-ray absorption spectroscopy, and infrared microspectroscopy, and highlights how these tools are useful to the medicinal chemist. A brief description of the principles of the techniques is given with emphasis on the advantages of using synchrotron radiation-based instrumentation rather than instruments using typical laboratory radiation sources. This review focuses on several recent applications of these techniques to solve inorganic medicinal chemistry problems, focusing on studies of cellular uptake, distribution, and biotransformation of established and potential therapeutic agents. The importance of using these synchrotron-based techniques to assist the development of, or validate the chemistry behind, drug design is discussed.
