Test beam measurements and computer simulations of the ATLAS ITk R2 silicon strip detector

Abstract

The ATLAS Inner Tracker, the future innermost part of the ATLAS detector, is an all-silicon tracker composed of pixel and strip modules, designed to cope with the extreme conditions expected during High-Luminosity LHC runs. Thorough testing of modules during the individual phases of their development is critical to ensure the required performance level of the whole tracker. This document presents results obtained from electron beam measurements of the ATLAS ITk R2 end-cap strip module. Key performance metrics are presented and discussed for both perpendicular and angled beam incidence. Computer simulations of the module were performed in the Allpix-Squared framework and the results were compared to experimental data.
