The ATLAS muon micromegas R&D project: towards large-size chambers for the s-LHC

Detectors based on the bulk-Micromegas technology exhibit position resolution better than 100 m m at counting rates of up to several tens of kHz/cm(2), along with trigger capabilities. These characteristics, combined with the detector's mechanical robustness and the possibility for cost-effective industrial production, makes them a promising candidate for the ATLAS Muon Spectrometer upgrade in a future luminosity enhancement of the LHC. The R&D project status will be presented together with the obtained results in the effort to define the baseline system specifications

Development of large size micromegas detector for the upgrade of the ATLAS muon system

With the luminosity upgrade of the LHC machine (SLHC, Super-LHC), the Muon system of the ATLAS experiment at CERN will also need a detector upgrade in the highest rapidity region. MAMMA, Muon ATLAS Micromegas Activity, is an ongoing R&D activity with the aim to develop large detectors based on the bulk-Micromegas technology for use in the ATLAS Muon Spectrometer. Micromegas is a good potential candidate for the construction of large muon chambers that combine trigger and tracking capability and can sustain high particle rates expected at the SLHC. A medium size Micromegas prototype, in scale 1:10 of the final chambers, has been built and evaluated in the laboratory and in beam tests at CERN. Results from the analysis of test-beam data are presented. The results indicate that large size Micromegas is a viable candidate for ATLAS Muon upgrade

Development of large size Micromegas detector for the upgrade of the ATLAS Muon system

International audienceWith 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
