Test-beam results & performance studies of the ATLAS Micromegas production modules / Scholer, Patrick Gerhard (Albert-Ludwigs-Universitaet Freiburg) /ATLAS Collaboration
The LHC at CERN plans to have a series of upgrades to increase its instantaneous luminosity to 7.5×10$^{34} cm^{−2}s^{−1}$.  The ATLAS experiment will upgrade its inner end-cap muon chambers to cope with the increased collision rate expected from the High-Luminosity-LHC. This project, called New Small Wheel, includes resistive Micromegas chambers together with small-strip Thin Gap Chambers (sTGC), conforming a system of ~2.4 million readout channels in total. [...]

Large Area Precision Cathode Boards for ATLAS Muon Upgrades / Shaked, Dan (Department of Particle Physics, The Weizmann Institute of Science) ; Sheppard, Damian Joseph (TRIUMF) /ATLAS Collaboration
The largest phase-1 upgrade project for the ATLAS Muon System is the replacement of the present first station in the forward regions with the so-called New Small Wheels (NSWs) during the long-LHC shutdown in 2019/20. The NSWs will be equipped with eight layers of small-strip thin gap chambers (sTGC) arranged in multilayers of two quadruplets, for a total active surface area of more than 2500 m^2. [...]

Using ALFA detectors for the LHC Beam Background Measurements / Dziedzic, Bartosz Sebastian (Institute of Nuclear Physics Polish Academy of Sciences, Krakow) /ATLAS Collaboration
This paper presents background measurements performed during special runs with high $\beta^\ast$ optics at injection energy using ALFA detectors in the ATLAS experiment. Such special runs require specific collimation scheme which allows to reduce beam induced background. [...]

Production of Micromegas and progress on the HV stability issues / Mancini, Giada (INFN e Laboratori Nazionali di Frascati) /ATLAS Collaboration
The ATLAS collaboration at LHC has endorsed the resistive Micromegas technology, along with the small-strip Thin Gap Chambers (sTGC), for the high luminosity upgrade of the first muon station in the high-rapidity region, the so called New Small Wheel (NSW) project. After the R&D;, design and prototyping phase, the first series production Micromegas quadruplets have been constructed at all involved construction sites: in France, Germany, Italy, Russia and Greece [...]

Searches for Heavy Resonances with the ATLAS detector / Stelzer-Chilton, Oliver (TRIUMF) /ATLAS Collaboration
Abstract: Many theories beyond the Standard Model predict new heavy resonances which would be accessible at the LHC. Searches for these new particles are performed in a range of decay channels using the ATLAS experiment at the LHC, including dilepton, dijet and diboson final states. [...]

Dark Matter searches with the ATLAS Detector / Balunas, William Keaton (University of Oxford, Particle Physics) /ATLAS Collaboration
The presence of a non-baryonic dark matter component in the Universe is inferred from the observation of its gravitational interaction. If dark matter interacts weakly with the Standard Model it could be produced at the LHC. [...]

Anomalous gauge couplings: Status of triple and quartic anomalous gauge couplings / Chau, Chav Chhiv (Carleton University) /ATLAS Collaboration
The talk summarizes the status of anomalous triple and quartic gauge couplings, covering the results reported by ATLAS and CMS. Some systematic uncertainties common to recent measurements are discussed. [...]

Effect of mesh geometry on resistive Micromegas for the ATLAS experiment / Sidiropoulou, Ourania (European Laboratory for Particle Physics, CERN) /ATLAS Collaboration
The ATLAS Experiment will use resistive Micromegas detectors for the upgrade of the forward Muon System (NSW, for New Small Wheel). With the test of the first production modules, instabilities in the detector operation have been observed, leading to a systematic revision of the selected construction components and working parameters.

Performance and Calibration of large area Micromegas Detectors for the ATLAS Muon Spectrometer Upgrade Using Cosmic Muons / Chevalerias, Thibault Jean Aime (IRFU, CEA, Université Paris-Saclay) /ATLAS Collaboration
The steadily increasing luminosity of LHC requires an upgrade to high rate and high-resolution capable detector technology for the inner end cap of the muon spectrometer of the ATLAS experiment. For precision tracking 4 types of 2 and 3 m2 large Micromegas quadruplets will provide 8 consecutive active layers, each, with 100 µm spatial resolution per individual plane [...]
