Measurement of the relative $B^{\pm}_c$/$B^{\pm}$ production cross section at ATLAS / Toms, Konstantin (University of New Mexico) /ATLAS Collaboration
The total cross section and differential cross sections for the production of $B_{c}^{\pm}$ mesons, times their branching fraction to $J/\psi \pi^{\pm}$, are measured relative to those for the production of $B^{\pm}$ mesons, times their branching fraction to $J/\psi K^{\pm}$. The data used for this study correspond to an integrated luminosity of $20.3\,\mathrm{fb}^{-1}$ of $pp$ collisions recorded by the ATLAS detector at the Large Hadron Collider in 2012 at a center-of-mass energy of $\sqrt{s} = 8$\,\TeV.

Measurements of $K^{0}_{S}$ and $\Lambda^0$ production in $t \bar{t}$ dileptonic events in $pp$ collisions at $\sqrt{s}=7~TeV$ with the ATLAS detector. / Calvente Lopez, Sergio (Physics Department, Universidad Autonoma de Madrid) /ATLAS Collaboration
Measurements of $K_S^0$ and $\Lambda^0$ production in $t\bar{t}$ final states have been performed. They are based on a data sample with integrated luminosity of 4.6 $\mathrm{fb}^{-1}$ from proton--proton collisions at a centre-of-mass energy of 7 TeV, collected in 2011 with the ATLAS detector at the Large Hadron Collider. [...]

The phase-1 upgrade of the ATLAS level-1 calorimeter trigger / Ermoline, Iouri (Michigan State University, Department of Physics and Astronomy) /ATLAS Collaboration
The ATLAS level-1 calorimeter trigger (L1Calo) is a hardware-based system that identifies events containing calorimeter-based physics objects, including electrons, photons, taus, jets, and missing transverse energy. In preparation for Run 3, when the LHC will run at higher energy and instantaneous luminosity, L1Calo is currently implementing a significant programme of planned upgrades. [...]

The ATLAS Electron and Photon Trigger Performance in Run 2 / ATLAS Collaboration /ATLAS Collaboration
ATLAS electron and photon triggers covering transverse energies from 5 GeV to several TeV are essential to record signals for a wide variety of physics: from Standard Model processes to searches for new phenomena in both proton-proton and heavy ion collisions. Main triggers used during Run 2 (2015-2018) for those physics studies were a single-electron trigger with ET threshold around 25 GeV and a diphoton trigger with thresholds at 25 and 35 GeV. [...]

The Micromegas chambers for the ATLAS New Small Wheel upgrade / Gnesi, Ivan (INFN Gruppo Collegato di Cosenza and Universita' della Calabria, Dipartimento di Fisica) /ATLAS Collaboration
The ATLAS collaboration at LHC has chosenthe resistive Micromegas technology, along withthe small-strip Thin Gap Chambers (sTGC), for the high luminosity upgrade of the first muonstation in the high-rapidity region, the so called New Small Wheel (NSW) project. After theR&D;, design and prototyping phase, the series production Micromegas quadruplets are beingconstructed at the involved construction sites in France, Germany, Italy, Russia and Greece.AtCERN, the final validation and the integration of the modules in Sectors are in progress.Theseare big steps forward for the installation of the first NSW, the NSW-A foreseen for the LHClong shutdown in 2020.

ATLAS Forward Proton Time-of-Flight Detector - the LHC Run2 performance and experiences / Sykora, Tomas (Charles University, Faculty of Mathematics and Physics, Prague) /ATLAS Collaboration
The performance of the ATLAS Forward Proton Time-of-Flight (ToF) Cherenkov detector is shown using the ATLAS collaboration data collected in the 2017 running period of the LHC Run2. The detailed analysis of the results, including detector efficiency and time resolution of the ToF is performed. [...]

Precision survey of the readout strips of small-strip Thin Gap Chambers using X-rays for the muon spectrometer upgrade of the ATLAS experiment / Lefebvre, Benoit (TRIUMF) /ATLAS Collaboration
The instantaneous luminosity of the Large Hadron Collider (LHC) will be increased by a factor of 5 following a series of upgrades of the CERN accelerator complex. In anticipation to the increased collision rate at the interaction point, the muon end-cap inner station of the ATLAS detector will be replaced by the so-called New Small Wheels (NSWs) during the LHC shutdown of 2019/2020.

Performance of the ATLAS Tile Calorimeter / Gololo, Mpho Gift Doctor (School of Physics, University of the Witwatersrand) /ATLAS Collaboration
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The scintillators are read out by wavelength shifting fibres to photomultiplier tubes (PMTs) at the back of each wedge-shaped calorimeter module. [...]
