Simulation of the Electrical Performance of the ITk ATLAS18 Test Diode and Main Sensors Before and After Irradiation / Zhao, Yuzhan (Carleton University (CA)) ; Dandoy, Jeff (Carleton University (CA)) ; Klein, Christoph Thomas (Carleton University (CA)) ; Keller, John Stakely (Carleton University (CA)) ; Staats, Ezekiel (Carleton University (CA)) ; Fadeyev, Vitaliy (University of California,Santa Cruz (US)) ; Ullan, Miguel (Consejo Superior de Investigaciones Cientificas (CSIC) (ES)) ; Unno, Yoshinobu (KEK High Energy Accelerator Research Organization (JP)) /ATLAS Collaboration
The ATLAS experiment will be replacing the current inner detector with the Inner Tracker (ITk) to accommodate the increased occupancy and radiation levels anticipated at the High-Luminosity LHC (HL-LHC). The ITk system consists of silicon-based pixel and strip sub-detectors. [...]

Proton Irradiation for Quality Assurance of ATLAS18 Strip Sensors with Birmingham MC40 Cyclotron / Thory-Rao, Thomas Merlin (University of Birmingham (GB)) ; Chisholm, Andrew Stephen (University of Birmingham (GB)) ; Kopsalis, Ioannis (National Technical Univ. of Athens (GR)) ; Fadeyev, Vitaliy (University of California,Santa Cruz (US)) ; Unno, Yoshinobu (KEK High Energy Accelerator Research Organization (JP)) ; Ullan, Miguel (Consejo Superior de Investigaciones Cientificas (CSIC) (ES)) /ATLAS Collaboration
The Birmingham MC40 Cyclotron is used to perform proton irradiations of silicon detector devices as part of the ongoing ATLAS ITk Strip Quality Assurance program. It provides a dedicated beamline delivering 27 MeV protons at currents up to a few μA, collimated to a square beam profile of 10 mm x 10 mm of roughly uniform intensity. [...]

New results on performance studies of the 3D modules ​ in tests beam for the ATLAS ITk detector / Ravera, Simone (INFN e Universita Genova (IT)) /ATLAS Collaboration
For the High Luminosity upgrade of the Large Hadron Collider, the current ATLAS Inner Detector will be replaced by an all-silicon Inner Tracker (ITk). The installation is foreseen during the next LHC Long Shut Down 3 (2026-2030). [...]

Evaluation of post-irradiation performance of ATLAS18 strip sensors affected by low p-stop issue / ATLAS Collaboration
During the production of the new ATLAS Inner-Tracker (ITk) strip sensors for the forthcoming High-Luminosity Large Hadron Collider (HL-LHC) upgrade, the collaboration observed indications of low p-stop doping in a few sensor batches. Quality Control measurements of full-size sensors from these batches showed indications of sensor areas with low inter-strip isolation. [...]

Analysis of unstable leakage current in ATLAS18 Strip Sensors after long-term tests / ATLAS Collaboration
With the upgrade of the LHC to the High-Luminosity LHC (HL-LHC), the Inner Detector will be replaced with the new all-silicon ATLAS Inner Tracker (ITk) to maintain tracking performance in a high-occupancy environment and to cope with the increase in the integrated radiation dose. Comprising an active area of 165m$^2$, the outer four layers in the barrel and six disks in the endcap region will host strip modules, built with single-sided micro-strip sensors and glued-on hybrids carrying the front-end electronics necessary for readout.

Quality Assurance During Production of ATLAS18 ITk Strip Sensors / Orr, Robert (University of Toronto (CA)) /ATLAS Collaboration
We describe the extensive quality assurance programme undertaken during the production of the ATLAS ITk strip sensors. Quality Assurance (QA) is the systematic process of preventing defects during production, rather than identifying them after the fact. [...]

Investigation of interstrip resistance and charge collection properties of the ATLAS18 strip sensor for HL-LHC ATLAS using 1 cm2 mini-strip sensors / ATLAS Collaboration
Towards high-luminosity operation of the Large Hadron Collider, starting in 2030, the Inner Detector of the ATLAS detector will be replaced by a fully-silicon-based Inner Tracker (ITk). The outer part consists of ~ 20,000 strip modules using a production version of the $9.8 \times 9.8~\mathrm{cm}^2$ sensors (ATLAS18 design version) with a strip pitch of $\sim 76~\mathrm{\mu m}$.

Measurement of Threshold Voltages in PTP Structures and Estimation of P-stop Densities Across an ATLAS18 Silicon Strip Sensor Wafer Using TCAD Simulations / Unno, Yoshinobu (KEK High Energy Accelerator Research Organization (JP)) /ATLAS Collaboration
A total of 24,010 AC-coupled silicon strip sensors, consisting of n-type strips in p-type silicon and referred to as ATLAS18, are currently in production for installation in the upgraded ATLAS Inner Tracker (ITk). In n-in-p strip sensors, a dense p-type region (e.g., p-stop implant) is essential for electrically isolating the n-type strips from a conductive inversion layer between the strips, caused by positive interface charges.

Violation of fundamental symmetries with B mesons at ATLAS - overview / Novotny, Radek (Czech Technical University in Prague (CZ)) /ATLAS Collaboration
The ATLAS experiment has developed a broad flavour-physics programme that exploits the large heavy-flavour yields produced at the LHC and the excellent tracking and muon performance of the detector. This talk will review recent ATLAS results based on the Run 2 data set and provide an outlook for Run 3 performance. [...]
