The Silicon Vertex Tracker (SVT) for the BaBar experiment at the PEP-II asymmetric B factory is a 5-layer device based on double-sided AC-coupled silicon strip detectors. It is read out by a custom IC, the AToM chip, that can simultaneously acquire, digitize and transmit data. The main purpose of the SVT is to accurately measure the decay position of the B mesons that are produced, which is essential for extracting CP asymmetries. Here, we report on the SVT design as well as progress on its fabrication and assembly.

Abstract
The Silicon Vertex Tracker (SVT) for the BaBar experiment at the PEP-II asymmetric B factory is a 5-layer device based on double-sided AC-coupled silicon strip detectors. It is read out by a custom IC, the AToM chip, that can simultaneously acquire, digitize and transmit data. The main purpose of the SVT is to accurately measure the decay position of the B mesons that are produced, which is essential for extracting CP asymmetries. Here, we report on the SVT design as well as progress on its fabrication and assembly.
