Building and Commissioning of the CMS Pixel Barrel Detector

The CMS pixel barrel detector is a complex system that consists of 768 segmented silicon sensor modules. The total number of readout channels in the system is about 48 million. An overview on the module assembly and qualification procedures as well as testing results will be presented. The assembly of the detector control and readout electronics on the supply tube, the integration of the final system and the installation into CMS will be explained. The strategy and results from the early commissioning of the complete system that includes the performance of the hardware and the data acquisition and control software will be reviewed.
