Abstract

The Pierre Auger Observatory is the largest facility worldwide designed and built to study ultra-high energy cosmic rays. Operated by an international collaboration of researchers from seventeen countries, its primary goal is the study of cosmic rays of the highest energies observed so far, in the region of 1017 eV and above. Data taken with it over the last decade have already led to major breakthroughs in the field of ultra-high energy cosmic rays. In the last two years, the Auger Collaboration has begun an effort of a significant upgrade of its capabilities, with an emphasis on an improved mass composition determination using the surface detectors of the Observatory. Known as AugerPrime, the upgrade will include new detectors, updated and more flexible surface detector electronics, a dedicated array of buried muon detectors, and an extended duty cycle for operations of the fluorescence detectors. The upgraded AugerPrime Observatory is foreseen to operate at least until 2025. This thematic project is nested in the broader effort of the upgrade of the Pierre Auger Observatory and aims the support for research activities of scientists from São Paulo at AugerPrime. The project extends the work already supported by FAPESP in previous thematic projects (1999/05404-3 and 2010/07359-6) and regular projects (2014/19946-4). The activities include the installation and characterization of new detectors, the replacement and maintenance of equipment at the site, the installation and operation of a remote-control room of the fluorescence telescopes at UNICAMP, the participation in data analyses going on in various tasks inside the collaboration, shifts of data taking, and meetings. AugerPrime is the unique cosmic-ray facility worldwide capable of assessing and answering fundamental questions about the origin of ultra-high energy cosmic rays in the next decade. (AU)
