Module building and performance measurements for the ATLAS ITk Pixel Outer Barrel demonstrator — •Sascha Dungs1,2, Bora Atlay3, Helge Beck4, Jörn Große-Knetter4, Matthias Hamer5, Fabian Hügging5, Kevin Kröninger1, Susanne Kühn2, Jörn Lange4, Jannicke Pearkes6, Heinz Pernegger2, Alexey Petrukhin3, Arnulf Quadt4, Steffen Schaepe2, and Jens Weingarten1 — 1TU Dortmund, Experimental Physics IV — 2CERN — 3Uni Siegen — 4Uni Göttingen — 5Uni Bonn — 6SLAC
As part of the Phase-II upgrade of the ATLAS detector, the current tracking detector will be replaced by an all-silicon detector, the Inner Tracker (ITk). The new pixel detector will consist of five central layers and several endcap discs with about 9000 modules. For qualification of system integration aspects, a demonstrator with representative components for the outer barrel layers of the pixel detector is currently being installed.
In this talk, the production of about 70 hybrid pixel modules with two or four readout chips will be presented. This production was done in different steps at various institutes. Particular focus will be placed on flex attachment and wirebond encapsulation. To qualify these production steps, a careful monitoring of the module performance is essential after each stage. An overview will be given about the testing procedure and the result of the performance measurements of these modules.
