The Phase-I Trigger Readout Electronics Upgrade of the ATLAS Liquid Argon Calorimeters / Vallier, Alexis Roger Louis (European Laboratory for Particle Physics, CERN) /ATLAS Collaboration
Electronics developments are pursued for the trigger readout of the ATLAS Liquid-Argon Calorimeter towards the Phase-I upgrade scheduled in the LHC shut-down period of 2019-2020. Trigger signals with higher spatial granularity and higher precision are needed in order to improve the identification efficiencies of electrons, photons, tau, jets and missing energy, at high background rejection rates, already at the Level-1 trigger.

Measuring the borders of the active area on silicon strip sensors / ATLAS Collaboration
Silicon strip sensors for the ATLAS Inner Tracker (ITk) have been designed to provide reliable particle detection in the high-radiation environment of the High-Luminosity Large Hadron Collider. One important design criterion for their development is the minimisation of inactive sensor area (bias ring, guard ring and edge implant surrounding the active sensor area), as inactive sensor areas impact the hermeticity of particle detection inside the detector. [...]

Mapping the in-plane electric field inside irradiated diodes / ATLAS Collaboration
A significant aspect of the Phase-II Upgrade of the ATLAS detector is the replacement of the current Inner Detector with the ATLAS Inner Tracker (ITk). The ATLAS ITk is an all-silicon detector consisting of a pixel tracker and a strip tracker. [...]

Trigger level analysis technique in ATLAS for Run 2 and beyond / Boveia, Antonio (Ohio State University) /ATLAS Collaboration
With the unprecedented high luminosity delivered by the LHC, detector readout and data storage limitations severely limit searches for processes with high-rate backgrounds. An example of such searches is those for mediators of the interactions between the Standard Model and dark matter, decaying to hadronic jets. [...]

The ATLAS Strip Detector System for the High-Luminosity LHC. / Arling, Jan-Hendrik (DESY, Hamburg and Zeuthen) /ATLAS Collaboration
The ATLAS experiment at the Large Hadron Collider (LHC) is currently preparing for a major upgrade of the Inner Tracking for the Phase-II LHC operation (known as HL-LHC), scheduled to start in 2026. In order to achieve the integrated luminosity of 4000 fb${}^{-1}$, the instantaneous luminosity is expected to reach unprecedented values, resulting in about 200 proton-proton interactions in a typical bunch crossing.

The ATLAS Hardware Track Trigger design towards first prototypes / Boveia, Antonio (Ohio State University) /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).

Effects of trapped charge on the signal formation and detection efficiency for subsequent pulses in irradiated silicon sensors / Diehl, Leena (Albert-Ludwigs-Universitaet Freiburg) ; Mori, Riccardo (Albert-Ludwigs-Universitaet Freiburg) ; Hauser, Marc Manuel (Albert-Ludwigs-Universitaet Freiburg) ; Wiik, Liv Antje Mari (Albert-Ludwigs-Universitaet Freiburg) ; Jakobs, Karl (Albert-Ludwigs-Universitaet Freiburg) ; Parzefall, Ulrich (Albert-Ludwigs-Universitaet Freiburg) ; Unno, Yoshinobu (KEK, High Energy Accelerator Research Organization) ; Fadeyev, Vitaliy (Santa Cruz Institute for Particle Physics, University of California Santa Cruz) /ATLAS Collaboration
Envisaged high energy physics experiments like the Future Circular Collider require unprecedented radiation hardness of the detectors, as well as short readout time due to high luminosity and occupancy. Silicon has proven to be extremely radiation hard, clear and fast signals can be recorded even at fluences close to $1\times 10^{16}~n_{eq}/\mathrm{cm}^{2}$. [...]
