Slide2The ATLAS ExperimentA Toroidal
LHC ApparatuSOne of two general-purpose detectors at the LHC (Large Hadron Collider)Will investigate a wide range of physics: Higgs boson, extra dimensions and particles that could make up dark matterMore than 1700 scientists from 37 countries involved

Slide20Muon Spectrometer Commissioning Status
Commissioning with cosmic rayLast MDT chambers are needed to be installed in endcap outer wheelAll installations and commissioning are needed to be finished before August 1 when the tunnel will be closed and beam collisions startCommissioning is important: checking both hardware and software for the ATLAS experiment
