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 I vertical bar eta vertical bar < 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. In this 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.
