The Silicon Strip Tracker (SST) is the intermediate part of the CMS Central
Tracker System. SST is based on microstrip silicon devices and in combinat
ion with pixel detectors and the Microstrip Gas Chambers aims at performing
pattern recognition, track reconstruction and momentum measurements for al
l tracks with p(T) greater than or equal to 2 GeV/c originating from high l
uminosity interactions at root s = 14 TeV at LHC. We aim at exploiting the
advantages and the physics potential of the precise tracking performance pr
ovided by the microstrip silicon detectors' on a large scale apparatus and
in a much more difficult environment than ever. In this paper we describe t
he actual SST layout and the readout system. (C) 1999 Elsevier Science B.V.
