“…The TilePPr receive digital data from the on-detector electronics at the accelerator frequency. Each TilePPr reads out and operates up to eight TileCal modules where each Compact Processing Module (CPM) [14] reads out 2 modules. The CPM serves as the core element of TilePPr reading out and operating the TileCal modules.…”

The Tile PreProcessor (TilePPr) is the core element of the Tile Calorimeter (TileCal) off-detector electronics for High-luminosity Large Hadron Collider (HL-LHC). The TilePPr comprises FPGA-based boards to operate and read out the TileCal on-detector electronics. The Tile Computer on Module (TileCoM) mezzanine is embedded within TilePPr to carry out three main functionalities. These include remote configuration of on-detector electronics and TilePPr FPGAs, interface the TilePPr with the ATLAS Trigger and Data Acquisition (TDAQ) system, and interfacing the TilePPr with the ATLAS Detector Control System (DCS) by providing monitoring data. The TileCoM is a 10-layer board with a Zynq UltraScale+ ZU2CG for processing data, interface components to integrate with TilePPr and the power supply to be connected to the Advanced Telecommunication Computing Architecture carrier. A CentOS embedded Linux is deployed on the TileCoM to implement the required functionalities for the HL-LHC. In this paper we present the hardware and firmware developments of the TileCoM system in terms of remote programming, interface with ATLAS TDAQ system and DCS system.

“…The CPM is responsible for distributing the LHC bunch-crossing clock to the detector, configuration of the on-detector electronics, data acquisition, cell energy reconstruction, and data transmission to the TDAQi. The interface FELIX for data readout will be implemented in the CPMs, whereas the TDAQi will provide the trigger primitives readout and monitoring [6].…”

The Large Hadron Collider (LHC) is undergoing a series of upgrades towards a High Luminosity LHC (HL-LHC) that will deliver five times the LHC nominal instantaneous luminosity. The ATLAS experiment is one of the experiments at the LHC that investigates elementary particle interactions in collisions of high-energy proton beams. To prepare for data taking in high-luminosity conditions, the ATLAS Tile Hadronic Calorimeter (TileCal) will replace completely on- and off-detector electronics using a new read-out architecture. The TileCal detector signals will be digitized by on-detector electronics and transferred to the TileCal PreProcessors (TilePPr), which comprise the main component of the off-detector electronics. In the TilePPr, the digitized data will be stored in pipeline buffers and be packed and read out to the Front-End LInk eXchange (FELIX) system upon the reception of a trigger decision. FELIX is a new detector readout component being developed as part of the ATLAS upgrade effort. FELIX is designed to act as a data router between the data acquisition detector control and TTC (Timing, Trigger and Control) systems and the new or updated trigger and detector front-end electronics. Whereas previous detector readout implementations relied on diverse custom hardware platforms, the idea behind FELIX is to unify all readout across one well supported and flexible platform.

“…The new readout strategy will make it possible for the on-detector electronics to digitize detector data and send it to the off-detector electronics at a bunch crossing frequency of 40 MHz, higher than 100 kHz of the present system. In the off-detector electronics, the Tile PreProcessor (TilePPr) [6] modules will reconstruct cell energies per bunch crossing and transfer the data to the Trigger and Data Acquisition Interface (TDAQi) boards [7]. The TDAQi boards will use the reconstructed cell energies to build trigger objects for the ATLAS calorimeter trigger system.…”

The electronics of the Tile Calorimeter at the ATLAS experiment will be replaced for the HL-LHC. The TileCal Phase-II upgrade project has undertaken an extensive R&D program. A Demonstrator module containing the upgraded on-detector readout electronics was built in 2014, evaluated in seven test beam campaigns, and inserted into one of the Tile Calorimeter modules at the ATLAS experiment in 2019. The module also provides backward compatibility of the Demonstrator module with the present ATLAS systems. We present the current status and test results from the Demonstrator module currently running at ATLAS.
