The ATLAS Hardware Track Trigger design towards first prototypes / Dittmeier, Sebastian Johannes (Physikalisches Institut) ; ATLAS TDAQ Collaboration /ATLAS Collaboration
In the High Luminosity LHC, planned to start with Run4 in 2026, the ATLAS experiment will be equipped with the Hardware Track Trigger (HTT) system, a dedicated hardware system able to reconstruct tracks in the silicon detectors with short latency. This HTT will be composed of about 700 ATCA boards, based on new technologies available on the market, like high speed links and powerful FPGAs, as well as custom-designed Associative Memories ASIC (AM), which are an evolution of those used extensively in previous experiments and in the ATLAS Fast Tracker (FTK).

Upgrade of the ATLAS MDT Readout and Trigger for the HL-LHC / ATLAS MDT Collaboration /ATLAS Collaboration
The luminosity increase of the LHC in Phase-II calls for an in-depth redesign of the entire MDT readout chain. While the high rate of primary detector signals requires increased bandwidth at each level of the data path, the MDT readout must, in addition, supply accurate coordinate information to the trigger system, leading to more reliable identification of high-pT tracks. [...]

New generation of RPC detector for the ATLAS Muon detector upgrade / Pizzimento, Luca (INFN Roma Tor Vergata and Universita' di Roma Tor Vergata, Dipartimento di Fisica) /ATLAS Collaboration
The architecture of the present ATLAS Muon spectrometer was designed for a luminosity of 1034 cm-2 s-1 with a security factor of 5 with respect to the simulated background rate, now confirmed by the LHC Run 1 results. Since HL-LHC will have a 5 times higher luminosity and a one order of magnitude bigger background, the demand in terms of performances increases, being the detector operated in a much harsher conditions.

Neutron Damage of ATLAS Endcap Alignment CCDs / Pazos Bonomi, Camila Ines (Brandeis University, Department of Physics) /ATLAS Collaboration
The endcap alignment system of the muon spectrometer of the ATLAS detector uses TC255P image sensors, which are charge-coupled devices (CCDs). Exposure to neutron irradiation in ATLAS can damage these CCDs. [...]

Enhancements in Functionality of the Interactive Visual Explorer for ATLAS Computing Metadata / Grigoryeva, Maria (M.V.Lomonosov Moscow State University) ; Titov, Mikhail (M.V.Lomonosov Moscow State University) ; Klimentov, Alexei (Brookhaven National Laboratory (BNL)) ; Padolski, Siarhei (Brookhaven National Laboratory (BNL)) ; Alekseev, Aleksandr (M.V.Lomonosov Moscow State University) ; Korchuganova, Tatiana (M.V.Lomonosov Moscow State University) /ATLAS Collaboration
The development of the Interactive Visual Explorer (InVEx), a visual analytics tool for ATLAS computing metadata, includes research of various approaches for data handling both on server and on client sides. InVEx is implemented as a web-based application which aims at the enhancing of analytical and visualization capabilities of the existing monitoring tools, and facilitate the process of data analysis with the interactivity and human supervision.
