The ATLAS Tile Calorimeter (TileCal) is the central part of the hadronic calorimeter of the ATLAS experiment and provides important information for reconstruction of hadrons. jets. hadronic decays of tau leptons and missing transverse energy. The readout is segmented into nearly 10000 channels that are calibrated by means of Cesium source. https://www.roneverhart.com/Cocomelon-Outdoor-Adventures-with-JJ-Audio-Play-Character/
