Oliver Pooth describes the silicon strip tracker of the CMS detector and discusses methods of quality control that are new to the field of particle detector physics. These methods were established to guarantee a uniform behaviour of all detector modules which were built and tested in various places worldwide.

In the post era of the Z and W discovery, after the observation of Jets at UA1 and UA2 at CERN, John Ellis visioned at a HEP conference at Lake Tahoe, California in 1983 “To proceed with high energy particle physics, one has to tag the avour of the quarks!” This statement re ects the need for a highly precise tracking device, being able to resolve secondary and tertiary vertices within high-particle densities. Since the d- tance between the primary interaction point and the secondary vertex is proportional tothelifetimeoftheparticipatingparticle,itisanexcellentquantitytoidentifypar- cle avour in a very fast and precise way. In colliding beam experiments this method was applied especially to tag the presence of b quarks within particle jets. It was rst introduced in the DELPHI experiment at LEP but soon followed by all collider - periments to date. The long expected t quark discovery was possible mainly with the help of the CDF silicon vertex tracker, providing the b quark information. In the beginning of the 21st century the new LHC experiments are beginning to take 2 shape. CMS with its 206m of silicon area is perfectly suited to cope with the high luminosity environment. Even larger detectors are envisioned for the far future, like the SiLC project for the International Linear Collider. Silicon sensors matured from small 1in. single-sided devices to large 6in. double-sided, double metal detectors and to 6in. single-sided radiation hard sensors.

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 CMS tracker. A review of the current findings of the RD50 collaboration tries to identify a sufficiently radiation hard base material while the subsequent chapter concentrates on quality assurance. In the final chapter a new interconnection technique between sensor and readout electronics is introduced and the results from first test prototypes are discussed.

The book describes the development of innovative silicon sensors known as ultra-fast silicon detectors for use in the space-time tracking of charge particles. The first comprehensive collection of information on the topic, otherwise currently scattered in existing literature, this book presents a comprehensive introduction to the development of ultra-fast silicon detectors with the latest technology and applications from the field. It will be an ideal reference for graduate and postgraduates studying high energy and particle physics and engineering, in addition to researchers in the area.
