Status and Performance of the Radio Detector of the Pierre Auger Observatory

Original language description

The Pierre Auger Observatory is a ground-based hybrid detector that measures cosmic rays above 10(17) eV with an array of 1661 water-Cherenkov detector (WCD) stations spread over 3000 km(2) and overlooked by 27 fluorescence telescopes. Over the last two decades, it has contributed significantly to our understanding of cosmic rays and multi-messenger astroparticle physics. However, fundamental questions about the origin, composition, acceleration mechanism, and propagation of ultra-high energy cosmic rays remain unanswered. The ongoing AugerPrime upgrade will improve the estimation of the mass composition of cosmic rays at the highest energies, which is closely related to other open questions and will improve multi-messenger capabilities. For inclined air showers with zenith angles greater than 65 degrees, this will be achieved by using the newly added Radio Detector (RD) antenna array. The RD consists of an antenna installed on top of each WCD to measure the radio emission from the air showers in the 30-80 MHz band. For inclined showers, the WCD predominantly measures the muonic component, and the RD measures the electromagnetic component. Over 700 fully upgraded stations are now taking data in the field, and the upgrade is expected to be completed this year. Currently, the RD collects data when triggered by the WCD. For inclined showers induced by neutral particles, especially photons, the muon content is often insufficient to trigger the WCD. Therefore, an RD trigger is also under development to enhance sensitivity to neutral particles. In this contribution, we present an overview of the RD upgrade and its expected performance for cosmic rays and photons. The significance of the RD in the current era of multi-messenger astroparticle physics is also discussed.
