ATLAS ITk Module Testing Quality Control — •Yannick Dieter, Fabian Hügging, Florian Hinterkeuser, Hans Krüger, Maximilian Mucha, Matthias Schüssler, Thomas Senger, and Jochen Dingfelder — Physikalisches Institut der Universität Bonn

With the upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC), the instantaneous luminosity will increase by a factor of 5 with respect to its design value from 2029 onward. The resulting unprecedented hit rates and radiation levels require major upgrades of the detectors located at the HL-LHC to meet the new challenging requirements.

For the upgrade of the ATLAS detector, a new all-silicon inner tracking detector (ITk detector) consisting of silicon strip and pixel modules will be installed to replace the currently operated Inner Detector. In total, approximately 10 000 new pixel detector modules have to be built and tested carefully to ensure that only fully functional detector modules are installed. Approximately 1000 pixel detector modules will be built and tested at the Forschungs- und Technologiezentrum Detektorphysik (FTD) in Bonn during the production of the ATLAS ITk pixel detector. For testing the electrical functionality of the detector modules an intensive quality control (QC) with dedicated testing setups was developed.

This talk gives an overview of the electrical QC for ATLAS ITk pixel detector modules in Bonn, with a focus on the newly developed test setup and first testing results.
