The CMS Forward Pixel Detector

At the core of CMS all-silicon tracker is the pixel detector. It provides fine granularity for charged track reconstruction with three-dimensional space measurements with resolutions on the order of ten microns. It is comprised of two parts ? the barrel detector and the forward disks. The disks are called the Forward Pixel detector and are being assembled at Fermilab, U.S.A. The detector modules for the disks consist of eighteen million pixels and the production begins in summer of 2006. The designs and the present status of the detector are reviewed here.
