The ATLAS Upgrade Project: Silicon Module Development by Dr. Sven Wonsak (University of Liverpool)
The seminar talk describes the upgrade of the central tracking system for the ATLAS experiment for the operation at the High Luminosity LHC (HL-LHC) starting 2029. At this time the LHC will have been upgraded to reach a peak instantaneous luminosity of 7.5×10^34 cm−2s−1, which corresponds to approximately 200 inelastic proton-proton collisions per beam crossing. The new Inner Tracker (ITk) will be operational for more than ten years, during which ATLAS aims to accumulate a total data set of 3,000 fb−1. Meeting these requirements presents a unique challenge for the design of an all-silicon tracking system that consists of a pixel detector at small radius close to the beam line and a large-area strip tracking detector surrounding it. The presentation will discuss the requirements of the new tracker, its layout and then focus on the technical description of the strip detector which will cover the outer region of the new Inner Detector with an area of ~165 m^2 silicon. This includes the results of measurements of prototype modules, observed issues and mitigation strategies.
