The BaBar Silicon Vertex Tracker (SVT) is a five layer device, made from double-sided silicon strip detectors and read out via a custom time-over-threshold circuit, the AToM chip. The SVT is an essential part of the physics program of BaBar, and is able to reconstruct B mason decay vertices with a precision sufficient to measure time-dependent CP violating asymmetries at the PEP-II asymmetric e(+)e(-) collider.

Abstract
The BaBar Silicon Vertex Tracker (SVT) is a five layer device, made from double-sided silicon strip detectors and read out via a custom time-over-threshold circuit, the AToM chip. The SVT is an essential part of the physics program of BaBar, and is able to reconstruct B mason decay vertices with a precision sufficient to measure time-dependent CP violating asymmetries at the PEP-II asymmetric e(+)e(-) collider. This report will give an overview of the SVT, with particular focus on the performance of the SVT, which has been taking colliding beam data since May 1999. (C) 2001 Elsevier Science B.V.
