Construction and Commissioning of the CMS Pixel Barrel Detector

The CMS BPIX detector system was assembled and fully tested at PSI before it was transported to CERN [ 1 ]. A slice of the CMS control and data acquisition system has been semp at PSI in order to have a tool for operating and testing larger segments of the pixel detector. 

In the first two sections the development of the testing procedure is described, before the construction of the BPIX detector is addressed. In particular the technique for mounting the modules on the support structure, the assembly of the detector control and readout electronics on the supply tube and the integration of the final system are explained. The following section focusses on the installation of the BPIX detector into the CMS detector. In the last section the results of the system tests are discussed and the performance of the BPIX during the first running period is reviewed. The chapter concludes with a summary.

Study of the Inclusive Beauty Production at CMS and Construction and Commissioning of the CMS Pixel Barrel Detector... 

The second part of the thesis focusses on the construction and commissioning of the CMS pixel barrel detector, the central part of the CMS detector with about 48 million readout channels. The CMS pixel detector allows to measure secondary vertices with high precision and thus plays a key role in the analysis of events with Z -quarks. 

The contributions to the construction and commissioning of the CMS pixel barrel detector made during this thesis were presented in this chapter. The construction of the BPIX detector included the mounting of the modules on the mechanical cooling structure, the assembly of the supply tube and the integration of the complete system.
