Abstract

The Silicon Vertex Tracker (SVT) of the BABAR experiment at the PEP-II asymmetric B factory is a five layer double sided, AC coupled silicon microstrip detector. It represents the crucial element to precisely measure the decay position of B mesons . The SVT architecture is shown and its performances, like hit resolutions and efficiencies, are described. Radiation issues are discussed and the alignment procedure for the SVT is described. As an example for the physics performance the B lifetime measurement, including B vertex reconstruction, is shown.
