The BTeV pixel detector system

BTeV is a collider experiment approved to run at the Tevatron at Fermilab. The experiment will conduct precision studies of heavy flavor decays, with particular emphasis on CP violation, flavor oscillations and rare decays. One of its unique features is a state-of-the art pixel detector system, designed to provide accurate measurements of the decay vertices of heavy flavored hadrons that can be used in the first level trigger. This will insure the ability to perform precision study of a variety of final states and is a key element of the rich phenomenology that will be explored by BTeV. The main design features of the pixel vertex detector are reviewed
