The electronics of the hadronic calorimeter of the ATLAS detector (TileCal) is being redesigned as part of the works that will lead to the High Luminosity Large Hadron Collider (HL-LHC). TileCal electronics is divided in front and back-end subsystems. While the front-end will be inside the detector, the back-end is planned to be off-detector inserted in an ATCA shelf. The main objective of this paper...
The Large Hadron Collider has envisaged a series of upgrades towards a High Luminosity LHC delivering five times the LHC nominal instantaneous luminosity. The ATLAS Phase II Upgrade will accommodate the detector and data acquisition system for the HL-LHC. In particular, the Tile Hadronic Calorimeter will completely replace front-end and back-end electronics using a new read-out architecture. The digitized...
This work presents the first prototype of the super Read-Out Driver (sROD) demonstrator board for the Tile Calorimeter Demonstrator project. This project aims to test the new readout electronics architecture for the Phase II Upgrade of the ATLAS Tile Calorimeter, replacing the front-end electronics of one complete drawer with the new electronics during the shutdown at the end of 2015, in order to...
The stand-alone test-bench deployed in the past for the verification of the Tile Calorimeter (TileCal) front-end electronics is reaching the end of its life cycle. A new version of the test-bench has been designed and built with the aim of improving the portability and exploring new technologies for future versions of the TileCal read-out electronics. An FPGA-based motherboard with an embedded hardware...
A potential upgrade for the front-end electronics, signal digitization, and data acquisition system of the ATLAS central hadron calorimeter for the High Luminosity Large Hadron Collider (HL-LHC) is described. A Demonstrator is being built to readout a slice of the TileCal detector with this system. The on-detector electronics includes up to 48 analog Front-end Boards for processing the PMT signals,...
This work presents the implementation of a functional super Read-Out Driver (sROD) demonstrator for the Phase II Upgrade of the ATLAS Tile Calorimeter (TileCal) in the LHC experiment. The proposed front-end for the Phase II Upgrade communicates with back-end electronics using a multifiber optical connector with a data rate of 57.6 Gbps using the GBT protocol. This functional sROD demonstrator aims...
TileCal is the central hadronic calorimeter of the ATLAS experiment at the LHC collider at CERN. The Read-Out Drivers (ROD) are the core of the off-detector electronics. The main components of the RODs are the Digital Signal Processor (DSP) placed on the Processing Unit (PU) dautherboards. This paper describes the DSP code and its performance with calibration and real data. The code is divided into...
