Nowadays the fundamental understanding of granular materials (a finite amount of macroscopic fragmented matter that interacts mainly by dissipative collisions and friction) flowing is one of the most exciting challenges. We could find these systems present in nature as in industry; i. e., in a rock avalanche or in silo downloading corn grains. Given that there are in the literature many theoretical studies done in order to understand its underlying rules an experimental setup capable to corroborate it is needed.
In the last years the X-ray tomography appeared to let us able to have an insight in granular materials at static conditions, as a non-invasive technique. But given that we could find a granular system in a fluid-like state the present tools used to study granular materials at static conditions are not suitable. In this way the present research is aimed in order to establish the main ideas concerning the features needed in an X-Ray machine capable to track the trajectories in a granular system at non-static conditions.
