The Run Control System and the Central Hint and Information Processor of the Data Acquisition System of the ATLAS Experiment at the LHC / Anders, G (CERN) ; Avolio, G (CERN) ; Lehmann Miotto, G (CERN) ; Magnoni, L (CERN)
The Trigger and Data Acquisition (TDAQ) system of the ATLAS detector is composed of a large number of distributed hardware and software components (about 3000 machines and more than 15000 concurrent processes at the end of LHC’s Run I) which in a coordinated manner provide the data-taking functionality of the overall system. The Run Control (RC) system steers the data acquisition by starting and stopping processes and by carrying all data-taking elements through well-defined states in a coherent way (finite state machine pattern). [...]

Intelligent operations of the data acquisition system of the ATLAS experiment at the LHC / Anders, G (CERN) ; Avolio, G (CERN) ; Lehmann Miotto, G (CERN) ; Magnoni, L (CERN)
The ATLAS experiment at the Large Hadron Collider at CERN relies on a complex and highly distributed Trigger and Data Acquisition (TDAQ) system to gather and select particle collision data obtained at unprecedented energy and rates. The TDAQ system is composed of a large number of hardware and software components (about 3000 machines and more than 15000 concurrent processes at the end of LHC’s Run 1) which in a coordinated manner provide the data-taking functionality of the overall system.

The Central Hint and Information Processor system for automation, error detection and recovery in the ATLAS TDAQ Controls framework / Avolio, Giuseppe (European Laboratory for Particle Physics, CERN) /ATLAS Collaboration
The ATLAS experiment at the Large Hadron Collider at CERN relies on a complex and highly distributed Trigger and Data Acquisition (TDAQ) system to gather and select particle collision data obtained at unprecedented energy and rates. The TDAQ Controls system is the component that guarantees the smooth and synchronous operations of all the TDAQ components and provides the means to minimize the downtime of the system caused by run-time failures.

Commissioning of the FASER Trigger and Data Acquisition Prior to Proton-proton Collision Data-taking at the LHC / Antel, Claire /FASER Collaboration
FASER is a newly installed experiment at the LHC designed to search for long lived particles produced in high energy proton collisions and decaying several 100 meters downstream. As the experiment aims to measure a rare hypothetical process, it is crucial that the experiment’s trigger and data acquisition (TDAQ) system runs reliably and with minimal deadtime, quick to catch errors and raise alerts. [...]

Implementation of the DAQ software in the ALTI Module of the ATLAS TileCal / Tlou, Sijiye Humphry (School of Physics, University of the Witwatersrand) /ATLAS Collaboration
The Tile Calorimeter (TileCal) is the central hadronic calorimeter (|eta|<1.7) of the ATLAS experiment, made out of iron plates and plastic scintillators. The TileCal is divided into three cylinders along the beam axis, each of which is azimuthally segmented into 64 wedge-shaped modules, staggered in the ϕ direction. [...]

Overview of the ATLAS Fast Tracker Project / Ancu, Lucian Stefan (Section de Physique, Universite de Geneve) /ATLAS Collaboration
The next LHC runs, with a significant increase in instantaneous luminosity, will provide a big challenge for the trigger and data acquisition systems of all the experiments. An intensive use of the tracking information at the trigger level will be important to keep high efficiency for interesting events despite the increase in multiple collisions per bunch crossing.

APPLICATIONS OF EXPERT SYSTEM TECHNOLOGY IN THE ATLAS TDAQ CONTROLS FRAMEWORK / Kazarov, A ; Corso-Radu, A ; Lehmann, G ; Magnoni, L ; Murillo Garcia, R ; Sloper, JE
The ATLAS Trigger-DAQ system is composed of O(10000) of applications running ~1500 computers distributed over a network. To maximize the experiment run efficiency, the Trigger-DAQ control system includes advanced verification, diagnostics and complex dynamic error recovery tools, based on an expert system. [...]
