The Design of the LHCb Silicon Tracker

The LHCb silicon tracker is a large-surface silicon micro-strip detector that will cover an important part of the LHCb tracking system. Its data will be used in the trigger to select high-p/sub T/ daughter particles from B-meson decays, and in the offline analysis to reconstruct trajectories of charged particles in the very forward region of the detector. Readout strips of up to 38 cm in length with strip pitches of approximately 200 mu m will be employed. For the readout, a custom developed front-end chip and a Gbit digital optical link will be used. The design of detector, silicon sensors and readout link is presented.
