The CMS Silicon Strip Tracker

The CMS strip tracker is the first large scale tracker entirely based on silicon detector technology. It consists of 198 m 2 of detector sensitive area instrumenting the inner region of the experiment with a pseudo-rapidity coverage of | η | < 2.5 . This instrument, together with a silicon pixel system, is expected to perform robust tracking and detailed vertex reconstruction while embedded in the LHC high radiation and high luminosity environment. The project is in a well advanced construction phase: the detector module production is completed, the integration of the single components into large sub-detector units is underway and the full tracker commissioning is about to start. s paper, after a description of the tracker layout, detector modules production overview and a summary of the integration procedures for the inner barrel part of the tracker will be reported.
