Slicing – a new method for non destructive 3D elemental sensitive characterization of materials

Abstract

The measurement of thin slices with a color X-ray camera allows the 3D reconstruction of elemental distributions with X-ray fluorescence.

2D and 3D Imaging of Li-Ion Battery Materials Using Synchrotron Radiation Sources

“…CCD energy dispersive array detectors have been used for full field micro-XRF for different applications [25]. A prototype pnCCD form IFG/pnSensor is may be the most advanced instrumentation available to date.…”

Fast X-ray microfluorescence imaging with submicrometer-resolution integrating a Maia detector at beamline P06 at PETRA III

“…Full XRF raster scanning in three dimensions is rarely applied due to the long measuring times. In contrast to confocal XRF (Fittschen & Falkenberg, 2011) or color X-ray cameras (Scharf et al, 2011;Garrevoet et al, 2014;Radtke et al, 2014), the best achievable resolution is limited by the beam size rather than capillary detector optics (! 10 mm).…”

X-Ray Imaging

“…The so-called 'Colour X-ray Camera' (CXC) is based on the combination of an energy-dispersive array detector for X-rays, in this case a pn-CCD, with polycapillary optics. For a full review on X-ray detectors we refer to Strüder et al [14], for elemental characterisation and metrological applications to Radtke et al [15]. Imaging is then achieved using multiframe recording of the energy and the point of impact of single photons.…”

“…Bent mirrors, crystals and multilayers, tapered glass monocapillaries, complex polycapillary lens systems, Bragg-Fresnel lens (BFL), 1-D and 2-D waveguides and refractive lenses have been developed and tested for use in micrometre to sub-micrometre focussing at synchrotron beamlines. 3-D elemental information is then obtained by consecutive layer-per-layer measurements of the sample which is moved perpendicular to the beam with steps corresponding to the thickness of the beam [15]. In a number of μ-XRF installations capillary optics are used as focussing devices, where they provide good lateral resolution but suffer from the short space (typically < 100 μm) between capillary tip and the sample.…”
