Abstract (englisch):

Despite enormous efforts in the last several decades, the origin of ultra-high-energy cosmic rays (UHECRs) -- their acceleration sites and acceleration mechanism(s) -- remains unidentified and is subject of active research. The progress made during that time, in particular by the Pierre Auger Observatory, established that significant advances in our understanding of the nature of UHECRs are only achieved with a better knowledge of their mass composition, i.e., through more precise measurements. To this end, the Pierre Auger Observatory is upgrading its large-aperture Surface Detector (SD) to enhance its mass sensitivity for the detection of the highest-energy cosmic rays ($E \gtrsim 4 \times 10^{19}\,$eV). As part of this effort, the AugerPrime Radio Detector (RD) will consist of over 1600 dual-polarized radio antennas mounted on top of each of the SD's water-Cherenkov detector (WCD) stations. The RD will be measuring the electromagnetic radiation in the 30$\,$MHz to 80$\,$MHz frequency band produced by highly inclined air showers with zenith angles $\gtrsim\,$65$^\circ$. Thus, the RD will allow us to determine the cosmic-ray energy by measuring the shower's electromagnetic component, which is largely independent of the cosmic-ray mass. ... mehr
