 Measuring luminosity with track counting in the ATLAS experiment / Moder, Paul (DESY, Hamburg and Zeuthen) /ATLAS Collaboration The precise measurement of the luminosity is one of the key requirements for every ATLAS analysis at the Large Hadron Collider (LHC) at CERN. Particularly in high precision experiments, the uncertainty on the luminosity can be one of the main limitations. [...] ATL-DAPR-SLIDE-2021-041.- Geneva : CERN, 2021 - 1 p.

 Luminosity measurement with the ATLAS experiment at the LHC / Carter, Joseph William (Department of Physics, University of Toronto) /ATLAS Collaboration Many physics measurements made by the ATLAS experiment at the LHC require a precise measurement of the integrated luminosity of the data sample. This talk will describe the ATLAS luminosity measurement for the full Run-2 dataset, including the absolute calibration of the luminosity scale using the van der Meer scan technique in dedicated LHC running, the extrapolation of this calibration to high-luminosity data-taking, and studies of the stability throughout the year.

 Luminosity determination in $pp$ collisions at $\sqrt{s} = 13\;\mbox{TeV}$ using the ATLAS detector at the LHC / Carter, Joseph William (Department of Physics, University of Toronto) /ATLAS Collaboration This poster describes the preliminary determination of the integrated luminosity for $pp$ collisions at $\sqrt{s} = 13\;\mbox{TeV}$ recorded by the ATLAS detector during Run 2 of the LHC in the years 2015-2018. The absolute luminosity scale was determined using van der Meer scans during dedicated running periods in each year, and extrapolated to the physics data-taking regime using complementary measurements from several luminosity-sensitive detectors.

 Luminosity Monitoring in $pp$ collisions using $Z\rightarrow \ell \ell$ events at $\sqrt{s} = 13$ TeV with the ATLAS detector / O'Keefe, Michael William (University of Liverpool) ; Klein, Uta (University of Liverpool) ; Lyons, Harry (University of Liverpool) ; Kretzschmar, Jan (University of Liverpool) ; Onyisi, Peter (University of Texas at Austin) ; Brock, Ian (University of Bonn) /ATLAS Collaboration The luminosity recorded by ATLAS can be monitored by measuring the production rate of the $Z$ boson by selecting events with two electrons or muons. The $Z$ production rate is corrected using trigger and reconstruction efficiencies determined from data, as well as a Monte Carlo correction for residual detector effects.

 Luminosity determination in pp collisions at $\sqrt{s}$ = 13 TeV using the ATLAS detector at the LHC / Wang, Hulin (University of Alberta) /ATLAS Collaboration An accurate measurement of the delivered luminosity is a key component of the ATLAS physics programme. The preliminary calibration of the integrated luminosity for the Run-2 ATLAS data sample of pp collisions at $\sqrt{s}$ =13 TeV is described.

 ATLAS Inner Tracker Pixel Outer Barrel Demonstrator / Zambito, Stefano (European Laboratory for Particle Physics, CERN) /ATLAS Collaboration For the high luminosity era of the Large Hadron Collider (HL-LHC) it is foreseen to replace the current inner tracker of the ATLAS experiment with a new detector to cope with the occurring increase in occupancy, bandwidth and radiation damage. It will consist of an inner pixel and outer strip detector aiming to provide tracking coverage up to |η|<4.

 A High-Granularity Timing Detector for the Phase-II upgrade of the ATLAS Calorimeter system: beam test results / Trincaz-Duvoid, Sophie (Laboratoire de Physique Nucleaire et de Hautes Energies (LPNHE), Sorbonne Universite, Universite de Paris, CNRS/IN2P3) /ATLAS Collaboration The expected increase of the particle flux at the high luminosity phase of the LHC (HL-LHC) with instantaneous luminosities up to L ≃ 7.5×10^34 cm−2 s-1 will have a severe impact on the ATLAS detector performance. The pile-up is expected to increase on average to 200 interactions per bunch crossing. [...] ATL-HGTD-SLIDE-2021-035.- Geneva : CERN, 2021 - 18 p.

 Measurements of Sensor Radiation Damage in the ATLAS Inner Detector using Leakage Currents / Grummer, Aidan (University of New Mexico) /ATLAS Collaboration Non-ionizing energy loss causes bulk damage to the silicon sensors of the ATLAS pixel and strip detectors.This damage has important implications for data-taking operations, charged-particle track reconstruction, detector simulations, and physics analysis. This talk presents simulations and measurements of the leakage current for the ATLAS pixel detector as a function of location in the detector and time, using data collected in Run 1 (2010-2012) and Run 2 (2015-2018) of the Large Hadron Collider.

 Measurement of the effective silicon band gap energy with the ATLAS Pixel detector / Grummer, Aidan (University of New Mexico) /ATLAS Collaboration Silicon sensor leakage currents are often used as a diagnostic tool for monitoring the bulk damage caused by non-ionizing energy loss. One of the key inputs to interpreting leakage current data is the effective band gap energy, which is used to correct for temperature variations in the current.

 Operational Experience and Performance with the ATLAS Pixel detector at the LHC / Bindi, Marcello (Georg-August-Universitat Goettingen, II. Physikalisches Institut) /ATLAS Collaboration The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector, that has undergone significant hardware and readout upgrades to meet the challenges imposed by the higher collision energy, pileup and luminosity that are being delivered by the Large Hadron Collider (LHC), with record breaking instantaneous luminosities of 2 x 1034 cm-2 s-1 recently surpassed. The key status and performance metrics of the ATLAS Pixel Detector are summarised, and the operational experience and requirements to ensure optimum data quality and data taking efficiency will be described, with special emphasis to radiation damage experience [...] ATL-INDET-SLIDE-2021-032.- Geneva : CERN, 2021 - 20 p.
