Figure 1
Height of the gauge volume (hgv) immersed in the sample compared with the information depth in real space 〈z〉R and in Laplace space 〈z〉Lap. Different modes of X-ray and synchrotron diffraction are shown: (a) the narrow-slit configuration with small gauge and (b) wide-slit configurations (AD – angular dispersion; ED – energy dispersive) for which the information depth 〈z〉Lap is defined by equation (3) and D denotes the thickness of the sample. |
