Abstract :
Micromegas is one of the detector technologies (along with small-gap Thin Gap Chambers) that has been chosen for the upgrade of the forward muon detectors of the ATLAS experiment, due to its precision tracking and trigger capability, covering an area of more than 1200m2. The design layout, the current status of the project and the necessary steps towards a complete operational system, ready to be installed in ATLAS in 2018, are reported. Performance studies of several micromegas prototypes are also presented, including spatial resolution for normal and inclined tracks, efficiency as well as studies of micromegas chambers inside a magnetic field. Finally, we report on the operation of prototype micromegas detectors installed in the ATLAS detector during LHC running at √s = 8 TeV.
