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. [...]

Investigation of the Current-Generation Mechanisms in the Edge Region of Planar Silicon Sensors using TCAD and TCT / Scharf, Christian (Humboldt University of Berlin (DE)) ; Lacker, Heiko Markus (Humboldt University of Berlin (DE)) ; Bloch, Ingo (Deutsches Elektronen-Synchrotron (DE)) ; Bruers, Ben (Deutsches Elektronen-Synchrotron (DE)) ; Ninca, Ilona-Stefana (Deutsches Elektronen-Synchrotron (DE)) ; 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
Radiation-hard silicon sensors used in high-energy physics experiments require a high electric field and are susceptible to surface breakdown at the edges of the planar sensors, especially at the tips of metal contacts or implants, where field peaks develop. These high-field regions, which are influenced by defects at the oxide interface and the geometry of the sensor, can give rise to avalanche breakdown. [...]

Current and low-field carrier mobility in silicon sensors irradiated to extreme fluences / Scharf, Christian (Humboldt University of Berlin (DE)) ; Lacker, Heiko Markus (Humboldt University of Berlin (DE)) ; Bloch, Ingo (Deutsches Elektronen-Synchrotron (DE)) ; Bruers, Ben (Deutsches Elektronen-Synchrotron (DE)) ; Fadeyev, Vitaliy (University of California,Santa Cruz (US)) ; Cindro, Vladimir (Jozef Stefan Institute (SI)) ; Mandic, Igor (Jozef Stefan Institute (SI)) ; Mikuz, Marko (Jozef Stefan Institute (SI)) ; Ullan, Miguel (Consejo Superior de Investigaciones Cientificas (CSIC) (ES)) ; Unno, Yoshinobu (KEK High Energy Accelerator Research Organization (JP)) /ATLAS Collaboration
We present a study of the forward and reverse current in silicon pad diodes irradiated to extreme neutron fluences of up to $5 \times 10^{17}\,n_{eq}/$cm$^2$, corresponding to expected fluences at the innermost radii of tracking detectors at a future circular hadron collider. At such fluences, the low-doped silicon bulk and the highly doped implant no longer behave like a typical pn diode. [...]

The upgrade of the ATLAS detector for HL-LHC / Metcalfe, Jessica (Argonne National Laboratory (US)) /ATLAS Collaboration
The Large Hadron Collider at CERN will undergo a luminosity upgrade increasing the number of particle interactions in the accelerator and its experiments. In order to optimize the potential physics reach, the ATLAS experiment will upgrade its detector including an all-new tracker, a forward high-granularity timing detector, and other systems for the trigger and data acquisition.

Solving the Sensor Cracking in ITK Strips / Blue, Andrew James (University of Glasgow (GB)) /ATLAS Collaboration
ATLAS is currently preparing for the HL-LHC upgrade, with an all-silicon Inner Tracker (ITk) that will replace the current Inner Detector. The ITk will feature a pixel detector surrounded by a strip detector, with the strip system consisting of 4 barrel layers and 6 endcap disks. [...]

Evaluation of Performance of the p-stop Process Splits in ATLAS18 strip sensors, Pre- and Post-Irradiation / Kozakova, Jana (Czech Academy of Sciences (CZ)) /ATLAS Collaboration
The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC), foreseen for 2030, requires the replacement of the ATLAS Inner Detector with a new all-silicon Inner Tracker (ITk). Radiation-hard $n^+$-in-$p$ micro-strip sensors developed for use in the ITk will be exposed to a total radiation fluence of up to $\Phi_{eq} = 1.6 \times 10^{15}$ 1 MeV $n_{eq}/cm^2$ and a total ionizing dose (TID) of 66 Mrad, both including a safety factor of 1.5.
