Resumo:One current debate in the field of high energy cosmic rays is the so called "muon puzzle". Recent studies showed that there is a muon excess of data over simulations. This, allied with the fact that the nature of the primary cosmic ray is sensitive to the muon number, requires a better understanding of the muon component of extensive air showers. In order to have a more precise measurement of this muon component, two RPCs were added below a tank located in the Pierre Auger Observatory, in the In ll array. The objective of this thesis is to obtain an averagemuonLDFin 10¹⁷ eVextensive air showers using those RPCs below the tank. To understand its feasibility and limiting factors, an HeitlerbasedMonte- Carlo toolwas built using a muon LDF parametrization of CORSIKA simulations. To use data measured by the RPCs, their state had to be validated. For this, the background frequencies in each pad of theRPCwere studied. The measured hits are a function of the efficiency of the RPCs.Monitoring data of the RPCs were analyzed to obtain their efficiency over time. To help differentiate between muon hits and EM hits, CORSIKA simulations were analyzed. Since this is a non-standard experimental setup, the state of the data acquisition system had to be validated.
