Performance of the ALICE Time-Of-Flight detector at the LHC

The Time-Of-Flight (TOF) detector of the ALICE experiment at the CERN LHC is based on Multi-gap Resistive Plate Chambers (MRPCs) technology. During the 2009-2013 data taking the TOF system had very stable operations with a total time resolution of 80 ps. Details of the different calibration procedures and performance with data from collisions at the LHC will be described.
