/ Agarwala, J (Pavia U.) ; Alviggi, M G (Naples U. ; INFN, Naples) ; Antonelli, M (Frascati) ; Anulli, F (INFN, Rome ; Rome U.) ; Arcangeletti, C (Frascati) ; Auricchio, S (Naples U. ; INFN, Naples) ; Bagnaia, P (INFN, Rome ; Rome U.) ; Bariani, S (Pavia U.) ; Baroncelli, A (Rome III U. ; INFN, Rome3) ; Bashta, I (Rome III U. ; INFN, Rome3) et al.
Large-size Resistive Micromegas have been chosen for the upgrade of the forward muon spectrometer of the ATLAS experiment, the New Small Wheel project. These chambers, together with small-strip Thin Gap Chambers (sTGC), allow reconstruction of high-momentum muon tracks in a high-radiation environment and provide a robust low-threshold single-muon trigger.

A full-size prototype of a Micromegas precision tracking chamber for the upgrade of the ATLAS detector at the LHC Collider has been built between October 2015 and April 2016. This paper describes in detail the procedures used in constructing the single modules of the chamber in various INFN laboratories and the final assembly at the Laboratori Nazionali di Frascati (LNF).

The Associative Memory System Infrastructures for the ATLAS Fast Tracker
/ Sotiropoulou, C L (Pisa U.) ; Maznas, I (Aristotle U., Thessaloniki) ; Citraro, S (Pisa U.) ; Annovi, A (INFN, Pisa) ; Ancu, L S (Geneva U.) ; Beccherle, R (INFN, Pisa) ; Bertolucci, F (Pisa U.) ; Biesuz, N (Pisa U.) ; Calabrò, D (INFN, Pavia) ; Crescioli, F (Paris U., VI-VII) et al.
The associative memory (AM) system of fast tracker (FTK) processor has been designed for the tracking trigger upgrade to the ATLAS detector at the Conseil Europeen Pour La Recherche Nucleaire large hadron collider. The system performs pattern matching (PM) using the detector hits of particles in the ATLAS silicon tracker. [...]

The Associative Memory (AM) system of the Fast TracKer (FTK) processor has been designed to perform pattern matching using as input the data from the silicon tracker in the ATLAS experiment. The AM is the primary component of the FTK system and is designed using ASIC technology (the AM chip) to execute pattern matching with a high degree of parallelism. [...]

The Associative Memory (AM) system, the main part of the FastTracker (FTK) processor, is designed to perform pattern matching using the information of the silicon tracking detectors. It finds track candidates at low resolution that are seeds for the following step performing precise track fitting. [...]

We have designed and built the facilities to assemble the inner layer of the precision tracking chambers (Monitored Drift Tubes, MDT) for the Muon Spectrometer of the ATLAS Experiment at LHC. This article describes in detail the tooling, the procedures and the quality control equipment used in the chambers assembly. [...]

The Pavia-Romal ATLAS MDT quality control system
/ Bini, C ; Calabro, D ; Cambiaghi, M ; Cardini, A ; Casani, S ; Ferrari, R ; Gaudio, G ; Giacalone, R ; Iuvino, G ; Lacava, F et al.
The physics at LHC imposes very severe requirements on the ATLAS muon detector, which translates into stringent requirements on drift-tubes wire tensioning, leak current, gas leak and wire positioning. In order to verify all these parameters prior to chamber construction, a dedicated quality control system was completely designed and built by our groups. [...]
