ATLAS Inner Detector: Commissioning with Cosmics Data

The ATLAS experiment at the CERN Large Hadron Collider (LHC) has started taking data in Autumn 2008 with the inauguration of the LHC. The determination of vertex position and charged particle tracks is performed in the Inner Detector which consists of pixel and microstrip silicon sensors and of straw drift tubes with transition radiation detector capability. All three subdetectors were run in standalone and also in a combined mode with other ATLAS subsystems. The current status of the three subsystems is reviewed, including results from recent data-taking periods, and from the detector alignment. Particular emphasis is given to the results obtained from cosmic muon runs in preparation for collision data.
