laboratory notes
A first-generation-synchrotron-class X-ray laboratory microsource, coupled to a three-pinhole camera, is presented. It allows (i) small- and wide-angle X-ray scattering images to be acquired simultaneously, and (ii) scanning small- and wide-angle X-ray scattering microscopy to be carried out. As representative applications, the structural complexity of a biological natural material (human bone biopsy) and of a metamaterial (colloidal nanocrystal assembly) are inspected at different length scales, studying the atomic/molecular ordering by (grazing-incidence) wide-angle X-ray scattering and the morphological/structural conformation by (grazing-incidence) small-angle X-ray scattering. In particular, the grazing-incidence measurement geometries are needed for inspecting materials lying on top of surfaces or buried underneath surfaces.
