Operating the 200 Gbps IRIS-HEP Demonstrator for ATLAS / Gardner Jr, Robert William (University of Chicago (US)) ; Vukotic, Ilija (University of Chicago (US)) /ATLAS Collaboration
The ATLAS experiment is currently developing columnar analysis frameworks which leverage the Python data science ecosystem. We describe the construction and operation of the infrastructure necessary to support demonstrations of these frameworks, with a focus on those from IRIS-HEP. [...]

Building Scalable Analysis Infrastructure for ATLAS / Gardner Jr, Robert William (University of Chicago (US)) ; Lancon, Eric (Brookhaven National Laboratory (US)) ; Vukotic, Ilija (University of Chicago (US)) ; Bryant, Lincoln (University of Chicago (US)) ; Golnaraghi, Farnaz (University of Chicago (US)) ; Stephen, Judith Lorraine (University of Chicago (US)) ; Taylor, Ryan (University of Victoria (CA)) ; Hu, Fengping (University of Chicago (US)) /ATLAS Collaboration
We explore the adoption of cloud-native tools and principles to forge flexible and scalable infrastructures, aimed at supporting analysis frameworks being developed for the ATLAS experiment in the High Luminosity Large Hadron Collider (HL-LHC) era. The project culminated in the creation of a federated platform, integrating Kubernetes clusters from various providers such as Tier-2 centers, Tier-3 centers, and from the IRIS-HEP Scalable Systems Laboratory, a National Science Foundation project. [...]

ATLAS analysis workflows using the EventIndex and the Event Picking Server for massive event picking and enhanced processing / Barberis, Dario (INFN e Universita Genova (IT)) ; Alexandrov, Evgeny (Joint Institute for Nuclear Research (RU)) ; Alexandrov, Igor (Joint Institute for Nuclear Research (RU)) ; Dimitrievska, Aleksandra (University of Birmingham (GB)) ; Iakovlev, Aleksandr (Joint Institute for Nuclear Research (RU)) ; Pagan Griso, Simone (Lawrence Berkeley National Lab. (US)) ; Turchikhin, Semen (INFN e Universita Genova (IT)) /ATLAS Collaboration
The ATLAS detector produces a wealth of information for each recorded event. Standard calibration and reconstruction procedures reduce this information to physics objects that can be used as input to most analyses; nevertheless, there are very specific analyses that need full information from some of the ATLAS subdetectors, or enhanced calibration and/or reconstruction algorithms. [...]

Investigating Data Access Models for ATLAS: A Case Study with FABRIC Across Borders and ServiceX / Vukotic, Ilija (University of Chicago (US)) ; Bryant, Lincoln (University of Chicago (US)) ; Gardner Jr, Robert William (University of Chicago (US)) ; Mc Kee, Shawn (University of Michigan (US)) ; Stephen, Judith Lorraine (University of Chicago (US)) ; Jordan, David Allen (University of Chicago (US)) /ATLAS Collaboration
This study explores enhancements in analysis speed, WAN bandwidth efficiency, and data storage management through an innovative data access strategy. The proposed model introduces specialized ‘delivery’ services for data preprocessing, which include filtering and reformatting tasks executed on dedicated hardware located alongside the data repositories at CERN’s Tier-0, Tier-1, or Tier-2 facilities.

Computing activities at the Spanish TIER-1 & TIER-2s for the ATLAS Experiment in the LHC Run-3 period and towards High Luminosity / ATLAS Collaboration
The Spanish cloud contributes 4% of ATLAS' computing resources both in terms of TIER-1 and TIER-2 sites. This talk delves into the specific architectures of the different sites contributing to our TIER-1 and federated TIER-2 site whilst also offering a wealth of figures quantifying their performance.

Building a Columnar Analysis Demonstrator for ATLAS PHYSLITE Open Data using the Python Ecosystem / Feickert, Matthew (University of Wisconsin Madison (US)) /ATLAS Collaboration
The ATLAS experiment is in the process of developing a columnar analysis demonstrator, which takes advantage of the Python ecosystem of data science tools. This project is inspired by the analysis demonstrator from IRIS-HEP. [...]

Enhancement of System Observability During System-Level Radiation Testing Through Total Current Consumption Monitoring / Slipukhin, Ivan (CERN) ; Coronetti, Andrea (CERN) ; Alía, Rubén García (CERN) ; Saigné, Frédéric (IES, Montpellier) ; Boch, Jérôme (IES, Montpellier) ; Dilillo, Luigi (IES, Montpellier) ; Aguiar, Ygor Q (CERN) ; Cazzaniga, Carlo ; Kastriotou, Maria ; Dodd, Torran
System-level testing of electronics is an affordable method of assessment of the performance of complete electronic systems designed for applications in the radiation environment. Compared to component-level testing, system-level test offers a much smaller degree of observability about the performance of particular system elements. [...]

Radiation Monitoring With Radiosensitive Pure-Silica Core Ultralow Loss Optical Fiber / Weninger, Luca (Lab. Hubert Curien, St. Etienne) ; Morana, Adriana (Lab. Hubert Curien, St. Etienne) ; Campanella, Cosimo (Lab. Hubert Curien, St. Etienne) ; Vidalot, Jeoffray (Lab. Hubert Curien, St. Etienne) ; Marin, Emmanuel (Lab.

Hubert Curien, St. Etienne ; IUF, Paris)
This article presents a new prospect for radiation detection exploiting the high radiation sensitivity of an ultralow-loss pure-silica core optical fiber (ULL-PSCF). This fiber exhibits very high transient X-ray radiation-induced attenuation (RIA) levels from UV to IR during irradiation, while its RIA quickly returns to a low permanent level after irradiation.

This study evaluates the lifetime and aging process of the aluminium electrolytic capacitors to be used in the new protection systems of the High Luminosity LHC superconducting magnets. The accelerated testing and analysis of several groups of capacitors aged for more than one year provided insights into their expected lifespan and aging process. [...]
