Status update of the Cell Integration Site for ATLAS ITk Pixel Detector in Bonn — •Alexandra Wald, Klaus Desch, Matthias Hamer, Florian Hinterkeuser, Fabian Hügging, and Hans Krüger for the ATLAS collaboration — Physikalisches Institut, University of Bonn, Germany

In conjunction with the high luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN, the current tracking system of the ATLAS experiment will be replaced by the Inner Tracker (ITk), an all-silicon detector consisting of 5 layers of pixel detectors and 4 layers of strip detectors. More than 8000 modules are installed in the pixel layers, which together have an active area of approx. 13m² and cover a pseudorapidity of up to 4. In order to built such a large detector in time, the integration of the ITk Pixel modules on their local support structures, as well as the quality control of individual loaded local supports will be distributed over many institutes. One of the assembly lines for loaded local supports will be setup at the University of Bonn. Due to the powering scheme of the ITk Pixel Detector, the quality control of a loaded local support is challenging in several aspects: loaded modules cannot be tested standalone, as the implemented serial powering scheme only allows for the simultaneous operation of a significant fraction of all modules on a loaded local support. In this presentation, the current status of the cell integration line in Bonn is presented, with a particular focus on the data acquisition infrastructure required for the QC setup, which is based on a FELIX server (Front-End LInk eXchange).
