Determination of beam intensities from proton scattering experiments between 2 MeV and 15 MeV — •Marco Menen, Felix Heim, Sarah Prill, Philipp Scholz, Michael Weinert, and Andreas Zilges — Institute for Nuclear Physics, University of Cologne

Cross section measurements are of great importance for nuclear astrophysics and our understanding of the structure of atomic nuclei. At the University of Cologne, we use two different target chambers dedicated to special types of experiments: The particle-γ spectrometer SONIC@HORUS is used to examine nuclear structure and determine branching ratios, while the target chamber dedicated for nuclear astrophysics is used to measure cross sections for astrophysically important nuclear reactions. Both target chambers will be presented with focus on their ability to determine precisely the number of impinging particles, which are needed to calculate absolute cross sections.
