The CMS detector has been designed to detect cleanly the diverse signatures of new physics at the Large Hadron Collider. It will do so by identifying and precisely measuring muons, electrons, photons, and jets over a large energy range [1-1],[1-2],[1-3],[1-4]. Experience has shown that robust tracking and detailed vertex reconstruction within a strong magnetic eld are powerful tools to reach these objectives. The overall layout of the CMS detector is illustrated in Colour Figs. 1.i, 1.ii and 1.iii. In this chapter an overview of the tracking system is given, together with a discussion of the physics goals and the design considerations which motivate our basic approach and technological choices. The subsequent chapters discuss in detail the three main sub-detector elements of the Tracker: the Pixel vertex detector system is described in Chapter 2, while the Silicon Strip (SST) and the Micro Strip Gas Chamber (MSGC) trackers are described in Chapters 3 and 4 respectively. Chapter 5 discusses the readout electronics of the Silicon Strip and MSGC de- tectors, the control and monitoring electronics and the low and high voltage power supplies. Chapter 6 describes the Tracker support structure, alignment, general engineering, services, beam pipe, installation and maintenance procedures. The safety aspects are also discussed in Chapter 6. In Chapters 7, 8 and 9 we discuss the detector simulation, the track and vertex re- construction algorithms, and nally the performance of the Tracker in its important aspects. In Chapter 10 cost, funding, institutional responsibilities and management of the Tracker project are described. Chapter 10 ends with the construction schedule and planning. The radiation environment and the simulation methods to evaluate it are described in Appendix A.
