Atlas Test Beam And MicroMegas Detectors

MicroMegas is one of the detector technologies (along with the small Thin Gap Chambers) that has been chosen for precision tracking and triggering purposes of the ATLAS muon forward detectors in the view of LHC luminosity increase. To fulfill the requirements of such upgrade, several prototype MicroMegas detectors were tested in recent test beam campaigns with high energy hadron beams at CERN. The following report describes the way that the MicroMegas detectors work and the procedure of the test beam at Atlas experiment at Cern .
