Etude en faisceau-test de la réponse des calorimètres de l'expérience ATLAS du LHC à des pions chargés d'énergie comprise entre 3 et 350 GeV

Abstract : ATLAS is one of the four experiments in construction at CERN. In order to study the performances of ATLAS detector, a full instrumented slice of the detector has been exposed to a test-beam during 2004. This document presents a study of the electromagnetic (LAr) and hadronic (TileCal) calorimeters to charged pions, measured in test-beam.
The present study begins with a description of the central calorimetry in ATLAS. For TileCal (central hadronic calorimeter), a global analysis of the font-end electronics test results is also presented.
The analysis of the calorimeters response continues with a study of pions that reach TileCal at minimum of ionization. Such a study is useful to check the standalone performances of TileCal. Then, the combined (LAr + TileCal) response is determined for high energy pions (20 to 350 GeV). The study finishes with a combined analysis of the calorimeters response in case of low energy pions (3 to 9 GeV)
