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 [...]

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. [...]

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.

FELIX: the new detector interface for the ATLAS experiment / Wu, Weihao (Brookhaven National Laboratory (BNL)) ; ATLAS Collaboration /ATLAS Collaboration
During the next major shutdown (2019-2020), the ATLAS experiment at the LHC at CERN will adopt the Front-End Link eXchange (FELIX) system as the interface between the data acquisition, detector control and TTC (Timing, Trigger and Control) systems and new or updated trigger and detector front-end electronics. FELIX will function as a router between custom serial links from front-end ASICs and FPGAs to data collection and processing components via a commodity switched network. [...]

Exploitation of heterogeneous resources for ATLAS Computing / Chudoba, Jiri (Academy of Sciences of the Czech Republic, Institute of Physics) /ATLAS Collaboration
LHC experiments require significant computational resources for Monte Carlo simulations and real data processing and the ATLAS experiment is not an exception. In 2017, ATLAS exploited steadily almost 3M HS06 units, which corresponds to about 300 000 standard CPU cores. [...]

The Phase-1 Upgrade for the Level-1 Muon Barrel Trigger of the ATLAS Experiment at LHC / Izzo, Vincenzo (INFN Napoli and Universita' di Napoli, Dipartimento di Fisica, Napoli) ; Aloisio, Alberto (INFN Napoli and Universita' di Napoli, Dipartimento di Fisica, Napoli) ; Giordano, Raffaele (INFN Napoli and Universita' di Napoli, Dipartimento di Fisica, Napoli) ; Perrella, Sabrina (INFN Napoli and Universita' di Napoli, Dipartimento di Fisica, Napoli) ; Vari, Riccardo (INFN Roma and Sapienza Universita' di Roma, Dipartimento di Fisica) /ATLAS Collaboration
The Level-1 Muon Barrel Trigger of the ATLAS Experiment at LHC makes use of Resistive Plate Chamber (RPC) detectors. The on-detector trigger electronics modules are able to identify muons with predefined transverse momentum values (pT) by executing a coincidence logic on signals coming from the various detector layers.

FATALIC: a fully integrated electronics readout for the ATLAS tile calorimeter at the HL-LHC / ATLAS Collaboration
The ATLAS Collaboration has started a vast program of upgrades in the context of high-luminosity LHC (HL-LHC) foreseen in 2024. The current readout electronics of every sub-detector, including the Tile Calorimeter (TileCal), must be upgraded to comply with the extreme HL-LHC operating conditions. [...]
