Assembly and testing of ATLAS ITk pixel detector modules during the production phase — Patrick Ahlburg, Yannick Dieter, Fabian Hügging, Florian Hinterkeuser, Hans Krüger, Maximilian Mucha, •Matthias Schüssler, 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 from 2029 onward. This results in unprecedented hit rates and radiation levels which require major upgrades of the detectors located at the HL-LHC in order to meet these 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 and replaces the currently operated Inner Detector. In total, approximately 10.000 new pixel detector modules have to be built and carefully tested to ensure that only functional detector modules are installed. At the Forschungs- und Technologiezentrum Detektorphysik (FTD) in Bonn, approximately 1000 pixel detector modules will be built and characterized 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 is necessary.

This talk gives an overview of the module assembly at Bonn and the electrical QC for ATLAS ITk pixel detector modules.
