The first part of this book introduces the basic principles necessary to understand silicon strip detectors in general and the specific implementation for the CMS experiment. It features an in- depth discussion of the fundamental background on semiconductor technology, which is followed by the most important aspects of designing and manufacturing a modern silicon strip sensor. A short introduction into the CMS experiment and its silicon tracker complements the first part. In the second part, the luminosity upgrade of the LHC accelerator (sLHC) is discussed and the challenges it poses to the...
