Abstract

The central component of the ATLAS inner tracker is the pixel detector. It consists of three barrel layers and three disk-layers in the endcaps in both forward directions. This amounts to a total active area of about 1.7 m² with over 80 million pixel cells. The huge number of readout channels necessitates a very complex services infrastructure for powering and readout as well as for detector and operator safety. The complete pixel detector system has been tested for the first time in a large scale system test at CERN from September 2006 to January 2007. An overview of the system test setup is given and key results are presented.
