 Grid production with the ATLAS Event Service / ATLAS Collaboration ATLAS has developed and previously presented a new computing architecture, the Event Service, that allows real time delivery of fine grained workloads which process dispatched events (or event ranges) and immediately streams outputs. The principal aim was to profit from opportunistic resources such as commercial cloud, supercomputing, and volunteer computing, and otherwise unused cycles on clusters and grids.

 Single Event Upsets in the ATLAS IBL Front End ASICs / Rozanov, Alexander (Centre de Physique des Particules de Marseille (CPPM), IN2P3-CNRS) /ATLAS Collaboration During operation at instantaneous luminosities of up to 2.1 10^{34} cm^{-2} s^{-1} the front end chips of the ATLAS innermost pixel layer (IBL) experienced single event upsets affecting its global registers as well as the settings for the individual pixels, causing, among other things loss of occupancy, noisy pixels, and silent pixels. A quantitative analysis of the single event upsets as well as the operational issues and mitigation techniques will be presented.. ATL-INDET-SLIDE-2018-383.- Geneva : CERN, 2018 - 1 p.

 The Social Content Strategy of the ATLAS Experiment / Sidoti, Antonio (Universita e INFN, Bologna) /ATLAS Collaboration Social media is an essential tool for communicating particle physics results to a wide audience. This presentation will explore how the nature of social media platforms has impacted the content being shared across them, and the subsequent effect this has had on the user experience.

 Recursive engagement: the public as data analysts and outreach creators / Kalderon, Charles William (Lunds universitet, Fysiska institutionen) /ATLAS Collaboration Two recent outreach projects are making use of public communities to enhance and build upon the first phases setup by physicists. “HiggsHunters” asked the public to search for displaced vertices in event displays, during which time a pool of trusted members arose in the associated discussion [...] ATL-OREACH-SLIDE-2018-381.- Geneva : CERN, 2018 - 20 p.

 Real time data analysis with the ATLAS trigger at the LHC in Run-2 / Beauchemin, Pierre-Hugues (Tufts University) /ATLAS Collaboration The trigger selection capabilities of the ATLAS detector have been significantly enhanced for the LHC Run-2 in order to cope with the higher event rates and with the large number of simultaneous interactions (pile-up) per proton-proton bunch crossing. A new hardware system, designed to analyse real time event-topologies at Level-1 came to full use in 2017. [...] ATL-DAQ-SLIDE-2018-380.- Geneva : CERN, 2018 - 1 p.

 The design and performance of the ATLAS Inner Detector trigger in high pileup collisions at 13 TeV at the Large Hadron Collider / Grandi, Mario (University of Sussex) ; Beauchemin, Pierre-Hugues (Tufts University) /ATLAS Collaboration The design and performance of the ATLAS Inner Detector (ID) trigger algorithms running online on the High Level Trigger (HLT) processor farm for 13 TeV LHC collision data with high pileup are discussed. The HLT ID tracking is a vital component in all physics signatures in the ATLAS Trigger for the precise selection of the rare or interesting events necessary for physics analysis without overwhelming the offline data storage in terms of both size and rate.

 Overview and performance of the ATLAS Level-1 Topological Trigger / Damp, Johannes Frederic (Institut fuer Physik, Universitaet Mainz) ; ATLAS Collaboration /ATLAS Collaboration In 2017 the LHC provided proton-proton collisions to the ATLAS experiment with high luminosity (up to 2.06x10^34), placing stringent operational and physical requirements on the ATLAS trigger system in order to reduce the 40 MHz collision rate to a manageable event storage rate of 1 kHz, while not rejecting interesting physics events. The Level-1 trigger is the first rate-reducing step in the ATLAS trigger system with an output rate of 100 kHz and decision latency of less than 2.5 μs.

 Development of a Highly Selective Muon Trigger Exploiting the High Spatial Resolution of Monitored Drift-Tube Chambers for the ATLAS Experiment at the HL-LHC / Kortner, Oliver (Max-Planck-Institut fuer Physik) /ATLAS Collaboration The High-Luminosity LHC will provide the unique opportunity to explore the nature of physics beyond the Standard Model. Highly selective first level triggers are essential for the physics programme of the ATLAS experiment at the HL-LHC, where the instantaneous luminosity will exceed the LHC design instantaneous luminosity by almost an order of magnitude.
