From June to November of 2018 I did a research internship at the Institut für Geophysik und extraterrestrische Physik (IGeP) in Braunschweig (Germany), carrying out impact experiments in their laboratories under the direction of Dr. Jürgen Blum. The research project consisted of two stages, the first one was to generate compact dust samples by high speed impacts and the second stage consisted in performing the 'Brazilian Disk Test' with these samples. With the first experiment we calculated the relation between the impact velocity and the compaction of the samples and with the second one, the relation between the tensile strength of the samples and their compaction. The main objective of this work is to find a relationship between the speed at which the samples were compacted and the energy that characterizes the collisions to be able to implement it in the future to the model of formation of giant planets.
