Description
The ATLAS Inner Tracker (ITk) is the future central tracking system designed for the high-luminosity upgrade of the ATLAS Experiment. It will consist of pixel detectors at small radius close to the beam pipe and large-area strip detectors surrounding them. The strip subsystem is split into a central region with rectangular sensors and two forward end-cap regions with sensors featuring radial strip geometry.
The Allpix-Squared framework has been used for simulation and performance studies of the rectangular ITk strip detectors, yielding results in good agreement with experimental data obtained from test beam measurements of strip detector prototypes at the DESY-II test beam facility. This contribution will summarize recent developments focused on extending the Allpix-Squared framework to enable simulation of end-cap strip detectors with radial geometry. Such simulations will provide further insight into ITk strip detector performance and extend the scope of the simulation studies to the entire ITk strip subsystem.
