Abstract	TileCal, the central hadronic calorimeter of the ATLAS detector is a key system to measure jets and the missing energy. It uses plastic scintillators interleaved by steel plates, with optical fibre readout and photomultipliers to detect the scintillating light produced by the passage of particles. The TileCal energy scale was obtained with beam tests and during operation dedicated calibration systems monitor each step of the readout chain to address response fluctuations. The detector performance in Run 2 was studied with isolated particles and data quality was assessed with the large sample of proton collisions. In this presentation, the methods and results of the TileCal Calibration, Operation and Performance in Run 2 are presented.
