Commissioning of the ALICE Time Projection Chamber

The Time Projection Chamber (TPC) is the main tracking detector of the heavy-ion experiment ALICE at the CERN Large Hadron Collider (LHC). The detector covers the pseudo-rapidity range | η | < 0.9 and is optimized to be operated in a high-multiplicity environment. The TPC has now been fully assembled and is undergoing commissioning with cosmic rays and tracks produced by a UV laser system. We will report on the status of commissioning including analysis of the quality of track reconstruction as well as on the overall performance parameters of the detector.
