Description
The Tile Calorimeter (TileCal) is the central hadronic calorimeter of the ATLAS experiment and is being upgraded for the High-Luminosity Large Hadron Collider (HL-LHC). The new TileCal electronics for the HL-LHC upgrade is validated using the test beam setup with beams of different particles species and energies in the SPS North Experiment Area. Muon test beams deposit a small but measurable energy in the calorimeter and the muon signal can be used to study the calibration of the different layers and cells.
This contribution presents a study of the muon response at different muon energies using the test beam data and Monte-Carlo simulations. The study was performed for the legacy electronic readout and the new upgrade readouts, as performance comparison is an important step in the preparation of the HL-LHC. In addition, the muon tagging capability of the upgrade electronics tested with Receiving Operating Characteristic curves will be discussed for possible implementation in the ATLAS muon trigger.
