CDF Run II silicon tracking projects

Design features, functionality, and expected performance are reviewed for the silicon charged particle track detectors to be used by the Collider Detector at Fermilab (CDF) during the upcoming Run II of the Fermilab Tevatron. The original design has been supplemented by addiition of a new layer of silicon mounted on the beam pipe that improves the vertexing performance of the combined assembly. Progress has been made in many areas of design and construction of the silicon sensors, readout electronics, and associated systems. The resulting detector array should provide substantial improvements in coverage and performance over those of previous CDF silicon vertex detectors.
