Description

The Tile Calorimeter (TileCal) is the central hadronic calorimeter of the ATLAS experiment at the Large Hadron Collider (LHC). It is a sampling calorimeter made of steel plates and plastic scintillators, read out by approximately 10,000 photomultipliers. In 2024, the LHC will be upgraded to the High Luminosity LHC (HL-LHC) allowing it to deliver up to 7 times the nominal instantaneous design luminosity. The Phase-II TileCal Upgrade will accommodate the detector and data acquisition system to the HL-LHC requirements. The on- and off-detector electronics will be completely redesigned, using a new readout architecture with a full-digital trigger system.
The upgraded on-detector electronics will transfer digitized data for every bunch crossing (~25 ns) to the Tile PreProcessor system (TilePPr) in the counting rooms, with a total data bandwidth of 40 Tbps. The TilePPr will store the detector data in pipeline memories to accommodate the new ATLAS Trigger and Data Acquisition architecture requirements, and will interface with the FELIX system and the first trigger level. A total of 32 TilePPr modules will be needed to read out the entire detector. The TilePPr module is composed of a full-size ATCA carrier blade equipped with four FPGA- based Compact Processing Modules with single-width AMC form factor.
This contribution presents the hardware and firmware developments, results and experiences for the final design of the Tile PreProcessor for the ATLAS Phase II Upgrade.
