 The Phase-I Trigger Readout Electronics Upgrade of the ATLAS Liquid Argon Calorimeters / Fortin, Etienne (Centre de Physique des Particules de Marseille (CPPM), IN2P3-CNRS) ; ATLAS LAr Collaboration /ATLAS Collaboration Electronics developments are pursued for the trigger readout of the ATLAS Liquid-Argon Calorimeter towards the Phase-I upgrade scheduled in the LHC shut-down period of 2019-2020. Trigger signals with higher spatial granularity and higher precision are needed in order to improve the identification efficiencies of electrons, photons, tau, jets and missing energy, at high background rejection rates, already at the Level-1 trigger [...] ATL-LARG-SLIDE-2020-055.- Geneva : CERN, 2020 - 16 p.

 ATLAS LAr Calorimeter Performance in LHC Run-2 / Mahon, Devin James (Nevis Laboratory, Columbia University) ; ATLAS LAr Collaboration /ATLAS Collaboration Liquid argon (LAr) sampling calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. In the first LHC run a total luminosity of 27 fb−1 has been collected at center-of-mass energies of 7-8 TeV.

 A High-Granularity Timing Detector for the Phase-II upgrade of the ATLAS Calorimeter system: detector concept, description and R&D and beam test results / Castillo Garcia, Lucia (Institut de Fisica d'Altes Energies (IFAE), Barcelona Institute of Science and Technology, Barcelona, Spain) /ATLAS Collaboration The increase of the particle flux (pile-up) at the HL-LHC with luminosities of L ≃ 7.5 × 1034 cm−2s−1 will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected.

 Performance of the ATLAS RPC detector and Level-1 muon barrel trigger at $\sqrt{s}$ = 13 TeV / Li, Heng (University of Science and Technology of China) /ATLAS Collaboration The ATLAS experiment at the Large Hadron Collider utilises a trigger system consisting of a first level hardware trigger and a higher level software trigger. The Level-1 muon trigger system selects muon candidates with six transverse momentum thresholds and associate them with a correct LHC bunch crossing.

 The ATLAS Strip Detector System for the High-Luminosity LHC / Rodriguez Rodriguez, Arturo (Albert-Ludwigs-Universitaet Freiburg) /ATLAS Collaboration The ATLAS experiment at the Large Hadron Collider is currently preparing for a major upgrade of the Inner Tracking for the Phase-II LHC operation, scheduled to start in 2026. The radiation damage at the maximum integrated luminosity of 4000/fb implies integrated hadron fluencies over 2x1016 neq/cm2 requiring a complete replacement of the existing Inner Detector.

 The ATLAS RPC system upgrade for the High Luminosity LHC / Sun, Yongjie (University of Science and Technology of China) /ATLAS Collaboration TITLE: The ATLAS RPC system upgrade for the High Luminosity LHC ABSTRACT: The present RPC trigger system in the ATLAS muon barrel was designed according to a reference luminosity of 10^34 cm-2 s-1 with a safety factor of 5, with respect to the simulated background rates, corresponding to about 300 fb-1 integrated luminosity. HL-LHC will reach a 7.5 times higher luminosity, and correspondingly higher rate, an expected integrated luminosity of 5000 fb-1 and a total duration extended until at least 2040, largely increasing the detector performance and longevity required.

 Design and construction of the mechanical structure for thin-gap RPC triplets for the upgrade of the ATLAS muon spectrometer / Kortner, Oliver (Max-Planck-Institut fuer Physik) /ATLAS Collaboration The advent of thin-gap RPCs with 1 mm gas gaps instead of 2 mm in the present RPCs opened the possibility to instrument the inner barrel layer of the ATLAS muon spectrometer where there is very limited amount of space in radial direction from the beam line. The environment is particularly dense in the barrel end-cap transition region. [...] ATL-MUON-SLIDE-2020-047.- Geneva : CERN, 2020 - 16 p.

 Studies of gas gaps current density in the ATLAS RPC detector during 2018 data taking at Large Hadron Collider / Krasnopevtsev, Dimitrii (University of Science and Technology of China) /ATLAS Collaboration The ATLAS Resistive Plate Chamber (RPC) detector is a tracking trigger, used to primarily select high momentum muons in the ATLAS barrel region (|\eta|<1.05) at the 40 MHz collision rate, and to provide muons azimuthal coordinates. The RPC system consists of about 3700 gas volumes covering a sensitive surface of about 4000 m^2.
