Beam tests on the ATLAS tile calorimeter demonstrator module

The Large Hadron Collider (LHC) Phase-II upgrade aims to increase the accelerator luminosity by a factor of 5–10. Due to the expected higher radiation levels and the aging of the current electronics, a new read-out system of the ATLAS experiment hadronic calorimeter (TileCal) is needed. A Demonstrator prototype of the electronics has been tested during different testbeam campaigns at the Super Proton Synchrotron (SPS) accelerator of CERN with the purpose of checking the calibration and determining the performance of the detector by exploiting the features of the interactions of different particles with matter. We present the current status and results where the Demonstrator new electronics were situated in calorimeter modules and data were collected by exposing it to beams of muons, electrons and hadrons, at various incident energies and impact angles.
