Description
The large Time-Of-Flight (TOF) array is one of the main detectors devoted to charged hadron identification in the mid-rapidity region of the ALICE experiment at the LHC; it allows separation among pions, kaons and protons up to few GeV/c, covering the full azimuthal angle and -0.9 < η < 0.9. The TOF exploits the innovative MRPC technology capable of an intrinsic time resolution better than 50 ps with an overall efficiency close to 100% and a large operation plateau; the full array consists of 1593 MRPC chambers covering a cylindrical surface of about 150 m2. In this report, the performance achieved by the TOF detector is shown; the results have been obtained during the 2010 and 2011 data taking periods, both with pp and Pb-Pb collisions.
