Abstract
SuperB is an asymmetric electron-positron collider planned to operate at very high luminosity (≥1036cm-2s-1) around the ϒ(4S) peak and in an energy range from the t/charm threshold to the ϒ(5S). It is an evolution of the SLAC PEP-II collider and its detector, BaBar. This paper describes the Silicon Vertex Tracker (SVT), one of the key elements of the SuperB detector, concentrating on the modifications and improvements adopted on the strip sensors for the external layers and on the baseline option for the innermost layer (Layer0), a thin (200 mm) double-sided silicon detector with short strips ("Striplets"), oriented at ±45°angle to the detector's edge.
