The Silicon Vertex Tracker (SVT) of the BaBar experiment at PEP-II, the crucial tool to measure the decay positions of B-mesons and extract CP-asymmetries, is described. SVT is structured in 5 layers made of double sided AC-coupled Silicon strip detectors , and read-out by a full- custom integrated circuit to amplify, digitize and transmit data. During its first year of operation, SVT has routinely performed spatial measurements with a precision of 10μm (inner layers) and 30μm (outer layers), with a single hit efficiency of 97%. Other relevant SVT features and their impact on physics measurements are reported. New measurements on radiation damage induced by iGeV electrons and electron-induced e.m. showers are described and compared with the data on SVT modules. New data indicate a greater radiation damage than expected from Cobalt source irradiations, setting a limit of 4 years at full PEP-II luminosity for the lifetime of the inner SVT layers.
