Abstract
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter that covers the central region of the ATLAS experiment at the Large Hadron Collider (LHC). The LHC will undergo a series of upgrades leading to the High-Luminosity LHC (HL-LHC). The TileCal Phase-II Upgrade will accommodate the detector readout electronics to meet the challenges of a 1 MHz trigger rate, higher ambient radiation levels, and increased pile-up conditions. The TileCal Phase-II upgrade project has undertaken an extensive R&D program.
The Demonstrator Phase-II Upgrade module was built in 2014 with upgraded readout electronics and backward compatibility with the ATLAS Trigger and Data Acquisition system. Its electronics were evaluated during test beam campaigns using the CERN SPS fixed target facility. The Demonstrator Phase-II Upgrade module operated under real detector conditions during Run 3. This contribution describes the hardware and software upgrades of the Demonstrator Phase-II Upgrade module and discusses the operational experience with this module within ATLAS, as well as the latest performance results.
