High-resolution X-ray imaging for lab-based materials research
The extension of limits of X-ray imaging techniques – in terms of spatial and temporal resolution as well as of material contrast – in the energy range from 5 to 70 keV has long exclusively taken place at third generation synchrotron beamlines. Yet, by using the latest generation of lab-sources together with novel X-ray detectors, results from microas well as sub-micrometer imaging are obtained...
متن کاملMultiple-wave diffraction in high energy resolution back-reflecting x-ray optics.
We have studied the effects of multiple-wave diffraction in a novel optical scheme recently published by Shvyd'ko et al. utilizing Bragg diffraction of x rays in backscattering geometry from asymmetrically cut crystals for achieving energy resolutions beyond the intrinsic width of the Bragg reflection. By numerical simulations based on dynamic x-ray diffraction and by experimentation involving ...
متن کاملBeam collimation with polycapillary x-ray optics for high contrast high resolution monochromatic imaging.
Monochromatic imaging can provide better contrast and resolution than conventional broadband radiography. In broadband systems, low energy photons do not contribute to the image, but are merely absorbed, while high energy photons produce scattering that degrades the image. By tuning to the optimal energy, one can eliminate undesirable lower and higher energies. Monochromatization is achieved by...
متن کاملHigh-energy x-ray micro-mapping of materials: engineering applications
Introduction and organization The use of synchrotron based high-energy x-ray scattering in materials/engineering programs is relatively new to both the synchrotron and engineering communities in the United States. In Europe such efforts are more advanced with engineering beam lines existent or under construction at ESRF in France, at PETRA III in Germany, and at Diamond in England. The industri...
