Figure 6
Compact MAD analyser block with a thin LogSpiral curved analyser crystal perpendicular to its Si(111) diffraction planes and working at a distance D = 150 mm in Laue transmission mode with X-rays having the Cu Kα1 energy. (a) Photograph of this setup during a laboratory experiment (beam paths are in green). (a′) Enlarged photograph of such a compact MAD block working in Laue transmission mode (beam paths are in green). (b) Schematic representation of beam paths filtered by this curved MAD filter and then cleaned/separated by a Soller collimator having long blades (60 mm) located and optimized for the distance Ds = 210–270 mm. |
