Getting Ready for Physics: Commissioning of the ALICE Experiment

ALICE at CERN-LHC is an experiment dedicated to the study of high-energy heavy-ion collision. In this paper we will briefly describe the experimental layout and give an overview on the installation status of the ALICE detector components including an outlook towards the completion of the staged detector setup. We will review the commissioning of the detector components with emphasis on the central detectors, in particular the time projection chamber (TPC). The commissioning took place in summer 2008 awaiting the first beams from the LHC in the fall. The result from commissioning are compared with the performance figures, which are outlined in the ALICE Physics Performance Reports.
