A proton irradiation site at the Bonn isochronous cyclotron at the Helmholtz Institut für Strahlen- und Kernphysik (HISKP) allows radiation damage studies of prototype silicon detectors for state-of-the-art, high-energy physics experiments such as ATLAS and BELLE 2. Especially pixel detectors, which are typically positioned close to the interaction point to enable high spatial resolution for tracking, are exposed to harsh radiation environments which dictate their lifetime. In order to verify that the detectors meet requirements, radiation damage studies are necessary for prototype detector concepts.
