ATLAS Technical Design Report Liquid Argon Calorimeter Phase-II Upgrade 15th June 2018 Abstract This Technical Design Report documents plans to upgrade the Liquid Argon calorimeters’ readout electronics for the ATLAS experiment for operation at the High Luminosity LHC. When the High Luminosity LHC begins operations in 2026 it will be able to reach a peak instantaneous luminosity of 7.5 × 1034 cm−2s−1, which corresponds to approximately 200 inelastic proton-proton collisions per beam crossing. The new Liquid Argon readout elec- tronics will be operational for more than ten years, during which time the LHC is expected to deliver 4 000 fb−1 of proton-proton collision data. These requirements are a significant challenge in the design of the new readout system. The design, construction and expected performance of the future readout electronics are presented in detail. These include the res- ults of measurements of prototypes and the plans for their mass production. This document also describes the management of the project, its schedule and major milestones. The costs of the new readout electronics and the collaboration that plans to build it are also presented. i ATLAS Technical Design Report Liquid Argon Calorimeter Phase-II Upgrade 15th June 2018 ATLAS Institutions Argentina Departamento de Física, Universidad de Buenos Aires, Buenos Aires Instituto de Física La Plata, Universidad Nacional de La Plata and CONICET, La Plata Armenia Yerevan Physics Institute, Yerevan Australia Department of Physics, University of Adelaide, Adelaide School of Physics, University of Sydney, Sydney School of Physics, University of Melbourne, Victoria Austria Institut für Astro- und Teilchenphysik, Leopold-Franzens-Universität, Innsbruck Fachhochschule Wiener Neustadt, Wiener Neustadt Azerbaijan Institute of Physics, Azerbaijan Academy of Sciences, Baku Belarus B.I.
