Expected Performance of the Phase-2 ATLAS Inner Tracker / Swift, Stewart Patrick (University at Albany, SUNY) /ATLAS Collaboration
In the high luminosity era (HL-LHC), the collision rate at the LHC is expected to be such that we expect 200 p-p interactions in a typical bunch crossing. To cope with this high rate, the ATLAS inner tracker is being completely redesigned, and will be replaced by an all-silicon system. [...]

Development and Performance of the Combined Jet Mass - LHCC Poster / Nelson, Michael Edward (University of Oxford, Particle Physics) /ATLAS Collaboration
The jet mass is a crucial discriminating variable in studies involving jet substructure.The calorimeter mass has been the canonical mass definition during the first run of ATLAS. This poster describes how the calorimeter mass can be combined with the track-assisted jet mass (which is obtained by associating inner detector tracks with calorimeter jets), to yield a new jet mass definition, the combined jet mass.

MUON RECONSTRUCTION PERFORMANCE OF THE ATLAS DETECTOR IN 2016 DATA / Marchese, Luigi (University of Oxford, Particle Physics) /ATLAS Collaboration
Muons are of key importance to study some of the most interesting physics topics at the LHC. We show the status of the performance of the muons reconstruction in the analysis of proton-proton collisions at the LHC, recorded by the ATLAS detector in 2016. [...]

Prospects of a search for $t\bar{t}$ resonances at the High Luminosity LHC with an upgraded ATLAS Detector / Duncan, Anna Kathryn (University of Glasgow, SUPA - School of Physics and Astronomy) /ATLAS Collaboration
A study of the expected mass reach of a search for new high-mass resonances decaying to a top quark pair using a simulation of the upgraded ATLAS experiment and using an integrated luminosity of 3000 fb$^{-1}$ from the High Luminosity LHC has been made. The simulation of the upgraded ATLAS experiment under HL-LHC conditions, including pileup, was done using parameterised estimates of the performance. [...]

Consolidation and upgrades of the ATLAS Tile Calorimeter / Cerda Alberich, Leonor (Instituto de Fisica Corpuscular (IFIC), Centro Mixto Universidad de Valencia - CSIC) ; ATLAS Tile Collaboration /ATLAS Collaboration
This is a presentation of the status of the ATLAS Tile Calorimeter during the EYETS and before starting 2017 data-taking. Updates on the upgrade of the readout system such as doubling the RODs output links and the number of processing units (PUs) are being worked on at the moment as well as items concerning the maintenance of the detector which involves issues such as cooling leaks and consolidation of the Low Voltage Power Supplies, which are being replaced if necessary.

ATLAS Electron Identification for the HL-LHC / Reynolds, Elliot (University of Birmingham) ; Nikolopoulos, Konstantinos (University of Birmingham) ; Anastopoulos, Christos (University of Sheffield) /ATLAS Collaboration
Over the next decade the LHC will receive substantial upgrades; increasing its luminosity by around a factor of 10, allowing it to collect 3000 $\mathrm{fb^{-1}}$ of data over its lifetime. This will increase the pileup from around 20 to 200, making particle identification (pID) much more challenging. [...]

ATLAS b-tagging efficiency measurements using a $t\bar{t}$ sample in pp collisions at $\sqrt s$=13 TeV / Li, Changqiao (University of Science and Technology of China) /ATLAS Collaboration
The $b$-tagging efficiency of the MV2c10 discriminant for track-jets and calorimeter-jets containing $b$-hadrons is measured using 36.5~fb$^{-1}$ of $pp$ collisions collected in 2015 and 2016 by ATLAS at $\sqrt{s}$=13~TeV. The measurements are performed using a tag-and-probe method to select a control sample of jets enriched in $b$-jets, by keeping events with a final state consistent with the process $pp\to t\bar{t}\to W^+bW^-\bar{b} \to e^\pm \mu^\mp \nu \bar\nu b \bar b$.

The Muon subsystem is comprised of four detector types: Resistive Plate Chambers (RPC) and Thin Gap Chambers (TGC) for trigger purposes, and Cathode Strip Chambers (CSC) and Muon Drift Tubes (MDT) for muon track reconstruction. The MDTs cover a large area at the outer part of the detector. [...]

Detector Control System for the ATLAS Forward Proton detector / Czekierda, Sabina (Institute of Nuclear Physics Polish Academy of Sciences, Krakow) /ATLAS Collaboration
The ATLAS Forward Proton (AFP) is a forward detector using a Roman Pot technique, recently installed in the LHC tunnel. It is aiming at registering protons that were diffractively or electromagnetically scattered in soft and hard processes. [...]

Real-time flavour tagging selection in ATLAS / Varni, Carlo (INFN Genova and Universita' di Genova, Dipartimento di Fisica) /ATLAS Collaboration
The ATLAS experiment includes a well-developed trigger system that allows a selection of events which are thought to be of interest, while achieving a high overall rejection against less interesting processes. An important part of the online event selection is the ability to distinguish between jets arising from heavy-flavour quarks (b- and c-jets) and light jets (jets from u-, d-, s- and gluon jets) in real-time.
