Development of Large-Size Micromegas Detector for the Upgrade of the ATLAS Muon System

Abstract : With the luminosity upgrade of the LHC machine (SLHC), the Muon System of the ATLAS experiment at CERN will also need a detector upgrade in the highest rapidity region. An R&D activity (MAMMA, for Muon Atlas MicroMegas Activity) has started with the aim to develop large detectors based on the bulk-Micromegas technology to be used in the ATLAS Muon Spectrometer. Micormegas are good candidates to construct large muon chambers that combine trigger and tracking capability and can cope with the high particle rates expected at SLHC. A medium size Micromegas prototype has been built and evaluated in the laboratory and in beam tests at CERN. Results from tests and basic ideas of the ATLAS Muon upgrade using Micromegas are presented.
