Test Beam Studies of Silicon Strip Detectors for the ATLAS ITk-Upgrade — •Moritz Wiehe — Albert-Ludwigs-Universität Freiburg

The inner tracking detector of the ATLAS-experiment will be upgraded for the application at the High Luminosity LHC. The current silicon tracker (SCT) and transition radiation tracker (TRT) will be replaced by an all silicon tracker (Inner Tracker, ITk).

To verify the functionality and performance of silicon strip detector modules, test beam studies are carried out. Results of a test beam at DESY in 2017 are presented, where two devices, a short strip barrel module and an R0 endcap module, were tested. The most important figures of merit are the efficiency, the noise level and tracking accuracy. Of special importance is, how the efficiency and spatial resolution depend on the track position.
