Description
The Pierre Auger Observatory is the largest observatory in the world for the detection of ultrahigh-energy cosmic rays. The Auger Collaboration started collecting data in 2004. In this period many significant discoveries were made, but some observations are still puzzling.
To improve the capability of the Observatory to identify the mass of the primary particles, the Observatory has started a major upgrade, called AugerPrime. The key points of the upgrade are the extension of the dynamic range of the surface detector (SD), the improvement of the data quality using a faster acquisition electronic, and the installation of new scintillator detectors on top of the 1660 water-Cherenkov detectors of the SD. After introducing the physics motivation of AugerPrime, technical details of the upgrade will be described, and the status of the deployment and the expected performance of the Observatory will be discussed.
