Figure 4
Three Ewald constructions show three different diffraction experiments in the qxqz plane of reciprocal space and illustrate (in red) the part of the reciprocal space which can be recorded by a static set-up. (a) White-beam incident spectrum with λmin < λ < λmax and energy-dispersive point detector at fixed scattering angle 2θ. Scan along a straight line in the qxqz plane of reciprocal space. The dotted lines show the scan orientation for different incident beam directions (for that case no additional Ewald spheres are shown). (b) Monochromatic incident radiation with wavelength λ and a line detector measuring the angular region 2θmin < 2θ < 2θmax. Scan along a curved line in the qxqz plane of reciprocal space. The dotted lines show the orientation of the scan for different directions of the incident beam (for that case no Ewald spheres are shown). (c) White incident spectrum with λmin < λ < λmax and energy-dispersive line detector measuring the angular region 2θmin < 2θ < 2θmax. Simultaneous scan of an area in the qxqz plane of reciprocal space between the two limiting Ewald spheres. |
