(a) Image of the detector and sample stage positioned about 5 m behind the focus of the KB-mirrors. b) Technical drawing of the tomography stage used for KB-illumination. The sample stage (yellow) including two compact linear piezo positioners for alignment of the axis of rotation, one rotation and a linear triaxial translation system for sample positioning, is placed on a kinematic mount of an aluminum plate which can manually be tilted by four adjusting screws in order to align the nick angle. The imaging system (Optique Peter with a PCO edge camera, black) was placed at distance behind the sample.
