Results from the pre-producton of the ITk Outer Barrel Bare Cell — •Nico Klein, Klaus Desch, Matthias Hamer, Florian Hinterkeuser, Alexandra Wald, and Dominik Hauner — Rheinische Friedrich-Wilhelms-Universität Bonn

The high luminosity upgrade for the Large Hadron Collider at CERN requires a complete redesign of the current tracking detector of the ATLAS experiment. The new Inner Tracker, the ITk Detector, will consist of a silicon pixel detector and a silicon strip detector. The ITk Pixel Detector is divided into three subsystems, the Outer Barrel (OB), Outer Endcaps and Inner System. In the OB, modules are loaded on cells (pyrolytic graphite tiles that are glued to an Aluminum-Graphite cooling block) before they are mounted on the local supports. These cells have a crucial role in the thermal performance of the modules, as they provide the connection between the modules and the cooling system. In order to meet the demanding requirements that are placed on the cooling system of the ITk Pixel Detector, the production of the Bare Cells goes through several quality control tests. In this talk I will present the results of the QC tests that have been performed on the pre-production OB bare cells.
