Dissertação (Mestrado em Fisica) - Universidade Federal de Goiás, Goiânia, 2018.http://repositorio.bc.ufg.br/tede/handle/tede/8821Liquid Argon Time Projection Chambers (LArTPCs) are ideal detectors for precision neutrino physics, but their technology is not completely mastered so far. In order to achieve a complete domain over the technology, the Liquid Argon In A Testbeam (LArIAT) experiment was built. LArIAT consists of a LArTPC placed at a dedicated calibration test beamline at Fermilab. In 2016 LArIAT performed the first pion-argon cross section measurement in history. The Aerogel Cherenkov detectors and the Muon Range Stack (MuRS) detector are auxiliary detectors whose purpose is to separate incoming pions and muons at the Time Projection Chamber (TPC) and separate the through-going muons and pions from the TPC, respectively. These detectors' data were not used on this first analysis due to the lack of people working on their data reconstruction. Therefore, on this work we used as tool the Geant4 Monte Carlo software to characterize the MuRS detector and quantify its purity and efficiency on muon/pion separation.application/pdfAcesso AbertoLArIATNeutrinoFermilabSimulação de Monte CarloMonte Carlo SimulationCIENCIAS EXATAS E DA TERRA::FISICADissertação
