description The Tile Calorimeter (TileCal) is the hadronic calorimeter of ATLAS covering the central region of the ATLAS experiment. TileCal will undergo a major replacement of its on- and off-detector electronics in 2024 for the high luminosity program of the LHC. The calorimeter signals will be digitized and sent directly to the off-detector electronics, where the signals are reconstructed and transmitted to the first level of trigger at a rate of 40 MHz. This will provide a better precision of the calorimeter signals used by the trigger system and will allow the development of more complex trigger algorithms. Three different options are presently being investigated for the front-end electronic upgrade. Extensive test beam studies are being employed to determine which option will be selected. The off-detector electronics are based on the Advanced Telecommunications Computing Architecture (ATCA) standard and are equipped with high performance optical connectors. The system is designed to operate in a high radiation environment and has a high level of redundancy. Field Programmable Gate Arrays (FPGAs) are extensively used for the logic functions of the off- and on-detector electronics in data processing. One hybrid demonstrator prototype module with the new calorimeter module electronics, but still compatible with the present system, is planned to be inserted in ATLAS in one of the next winter shutdowns. This contribution presents the components of the Tile Calorimeter upgrade for the high luminosity LHC, the production and performance of the prototype of the read-out electronics, the results of the beam tests at CERN and the plans for the next years.

The TileCal will undergo a major replacement of its on- and off-detector electronics in 2024 for the high luminosity program of the LHC. The TileCal signals will be digitized and sent directly to the off-detector electronics, which will store them in fixed-latency buffers and digitally construct and transmit trigger sums for the Level-1 trigger at a rate of 40 MHz. The improved signal resolution and precision will allow more complex and effective algorithms to be implemented in the Level-1 trigger hardware. Three different front-end options are currently being investigated for the TileCal upgrade with extensive test beam studies to determine which option will be selected. The off-detector electronics are based on the Advanced Telecommunications Computing Architecture (ATCA) standard and are equipped with large, modern FPGAs and high-performance optical links. The on-detector electronics are designed to operate in a high radiation environment and has a high level of redundancy. The large scale, high performance FPGAs are also extensively used for the logic functions and data links in data acquisition for on-detector electronics. A hybrid Demonstrator prototype with the new calorimeter module electronics, but still compatible with the present system, is planned to be inserted in ATLAS in one of the next winter shutdowns. We present the components of the Tile Calorimeter upgrade for the high luminosity LHC, the production and performance of the readout electronics prototypes, the results of the beam tests at CERN and the plans for the next years.ATL-TILECAL-PROC-2017-011oai:cds.cern.ch:22732922017-07-05
