Testing the Limits of ITkPixV2 / Le Pottier, Luc Tomas (University of California Berkeley (US)) ; Garcia-Sciveres, Maurice (Lawrence Berkeley National Lab. (US)) ; Heim, Timon (Lawrence Berkeley National Lab. (US)) ; Mironova, Maria (Lawrence Berkeley National Lab. (US)) ; Foster, Liam (University of California Berkeley (US)) /ATLAS Collaboration
The ITkPixV2 readout chip is the production readout chip for the ATLAS Phase 2 upgrade for the High-Luminosity LHC of the ATLAS inner detector, scheduled for commissioning at the start of 2029. The innermost layers of the ATLAS ITk pixel detector are expected to reach maximum hit rates of 3GHz/cm$^2$, a total radiation dose of 1 GRad, and data readout rates of 5Gbps, with an operational lifetime of over a decade.

Performance of the High-Level Trigger System at CMS in LHC Run-2 / Choudhury, Somnath (Bangalore, Indian Inst. Sci.) /CMS Collaboration
The CMS experiment at the LHC selects events with a two-level trigger system, the Level-1 (L1) trigger, and the high-level trigger (HLT). The HLT reduces the rate from 100 to about 1 kHz and has access to the full detector readout and runs a streamlined version of the offline event reconstruction. [...]

Evolution from Run 2 to Run 3 / Kazarov, Andrei (NRC Kurchatov Institute PNPI (RU)) /ATLAS Collaboration
The ATLAS experiment at the Large Hadron Collider (LHC) operated very successfully in the years 2008 to 2018, in two periods identified as Run 1 and Run 2. ATLAS achieved an overall data-taking efficiency of 94\%, largely constrained by the irreducible dead-time introduced to accommodate the limitations of the detector read-out electronics. [...]

The LHCb DAQ Upgrade for LHC Run3 / Colombo, Tommaso (CERN) ; Durante, Paolo (CERN) ; Galli, Domenico (INFN, Bologna) ; Marconi, Umberto (INFN, Bologna) ; Neufeld, Niko (CERN) ; Pisani, Flavio (CERN ; INFN, Bologna ; Bologna U.) ; Schwemmer, Rainer (CERN) ; Valat, Sébastien (CERN) ; Voneki, Balazs (CERN)
In order to optimize the physics reach in the large hadron collider (LHC) Run3, foreseen in the years 2021 and beyond, the LHC beauty experiment collaboration has decided to re-design its detector and the data acquisition system (DAQ). The new detector will operate at the LHC bunch-crossing frequency of 40 MHz without hardware trigger. [...]

Commissioning of L1Calo Phase I Upgrade at ATLAS: development and testing of eFEX and FTM modules / ATLAS Collaboration
The ATLAS level-1 calorimeter trigger (L1Calo) is a hardware system that identifies events containing calorimeter-based physics objects. In preparation for Run 3 with increased pileup ($\mu\sim65$), L1Calo is currently implementing a significant programme of planned upgrades. [...]

ATLAS Tile Calorimeter Conditions Database architecture and operations in Run-2 / Smirnov, Yuri (Northern Illinois University) ; Chakraborty, Dhiman (Northern Illinois University) ; Solodkov, Alexander (Institute for High Energy Physics of the National Research Centre Kurchatov Institute, Protvino) ; Harkusha, Siarhei (Institute of Physics, National Academy of Sciences) /ATLAS Collaboration
An overview of the Conditions Database (DB) structure for the hadronic Tile Calorimeter (TileCal), one of the ATLAS Detector sub-systems, is presented. ATLAS Conditions DB stores the data on the ORACLE backend, and the design and implementation has been developed using COOL (Conditions Objects for LCG) software package as a common persistency solution for the storage and management of the conditions data.

EUDAQ2 -- A Flexible Data Acquisition Software Framework for Common Test BeamsEUDAQ2—A flexible data acquisition software framework for common test beams / Liu, Y. (DESY) ; Amjad, M.S. (University Coll. London) ; Baesso, P. (Bristol U.) ; Cussans, D. (Bristol U.) ; Dreyling-Eschweiler, J. (DESY) ; Ete, R. (DESY) ; Gregor, I. (DESY) ; Huth, L. (DESY) ; Irles, A. (Orsay, LAL) ; Jansen, H. (DESY) et al.
The data acquisition software framework, EUDAQ, was originally developed to read out data from the EUDET-type pixel telescopes. This was successfully used in many test beam campaigns in which an external position and time reference were required. [...]

Software based control and monitoring of a hardware based track reconstruction system for the atlas experiment / Sottocornola, Simone (INFN Pavia and Universita' di Pavia, Dipartimento di Fisica)
During the Run-2 of the Large Hadron Collider (LHC) the instantaneous luminosity exceeds the nominal value of $10^{34}$ cm$^{-2}$ s$^{-1}$ with a 25 ns bunch crossing period and the number of overlapping proton-proton interactions per bunch crossing increases up to about 80. [...]
