The proposed Micro Computed Tomography device should be able to obtain high-quality images of a sample on the micro level (with a spatial resolution of structures > 5 micro meters). Moreover, a large process space (1 m3) for quasi-dynamic in-situ measurements, for example the particle loading within a tension-compression loading setup. Since often the areas of interest of a sample to be resolved are not known prior to recording, an efficient local enhancement of the resolution during recording should be possible. The Micro Computed Tomography needs to have maximum flexibility and versatility in terms of the media densities and sample thicknesses to be examined. A design as full сlosed device according to the X-ray protection ordinance is required. The Micro Computed Tomography is mainly used for studies of particulate materials and porous media in the research area of Particle Technology, such as mechanisms of shape and microstructure formation, deformation and breakage mechanisms of agglomerates, flow and compression behavior of cohesive bulk materials as well as mechanisms of the particle separation with filter media. microstructure of the porous filter media for the coupled flow, particle and deformation simulation models. Micro-computed tomography will provide the key measuring data for generating the real microstructure of the materials using the Discrete Element Method, as well as for validating simulations of particle systems, flows, and filter media.Moreover, the proposed Micro Computed Tomography device will be used in the areas of materials science (characterization of the microstructure, deformation and damage mechanisms of construction materials), measurement technology (metrological development of computer topography measuring devices), and materials testing (relationships between the microstructure and mechanical properties of materials, their failure mechanisms).
