In this scientific instrumentation project, we propose to develop and characterize an innovative photoelectronic device to record Cherenkov photons produced in water. We named this device C-ARAPUCA. This device will be installed on a Water-Cherenkov Detector specially built to study its performance. The operating principle of C-ARAPUCA is similar to that of X-ARAPUCA, that is, trapping ph…
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 maj…
The study of solar activity is a very active area of research due to the increased interest in the relationship between the cycles of sun and weather. The study of solar activity offers the potentiaI for long-range prediction of the behavior of the Sun and associated changes in climate. Many events that initially appeared to be random, for example, global effects such as EI Nino and La Ni…
The Pierre Auger Observatory, located in Argentina, studies cosmic rays with energy above 100 PeV. The Observatory consists of an array of 1660 water-Cherenkov detectors, spread in an area of 3000 squared kilometres, and 27 fluorescence telescopes, which detect extensive air showers produced by cosmic rays. Recent results show that more accurate data about the composition of these particl…
In the search for understanding of the formation and development of the universe cosmic ray detection has a fundamental role. Especially for very high energies, its origin is weakly known. The ultra-energy cosmic rays have energies between 10E17 eV to 10E20 eV, and its study may reveal a nature of yet unknown forces in the universe. High energy muons can provide information about the pro…
This research project includes the study of the cosmic ray flux in the city of São Paulo and the effects of this radiation in gravitational antenna Mario Schenberg. Will be held a Monte Carlo simulation of the passage of cosmic radiation through the building and detector of gravitational waves using the Geant4 toolkit of CERN. The energies of normal modes of resonant sphere will be calc…
A detector with 12,000 liters of water will be used to measure the average life time of muons. This detector uses the Cherenkov effect in water to measure the time decay of muons of cosmic radiation. The distortion in the distribution of decay times of the muons due to the capture of negative muons will be studied to obtain the value of the average life time of muon in the free space. The…

The Pierre Auger Observatory was built in Argentina to investigate the astrophysical origin and characteristics of cosmic rays with energies above 100 PeV. The hybrid design of the Observatory comprises a set of 27 fluorescence telescopes overlooking an area of 3000 km² covered by an array of 1660 water-Cherenkov detectors. The Pierre Auger Collaboration has measured with unprecedented pr…
Charged particles with energies ranging from a few times 10e6 eV up to 10e20 eV are continuously impinging on the Earth's atmosphere. Their study constitutes an important field of research in both astronomy and particle physics, and some cosmic ray related effects even have significance for the public's every-day life. High energy muons can provide information about the processes occurrin…
