✦ Synopsis

The Online Silicon Vertex Tracker (SVT) is the trigger processor dedicated to the 2-D reconstruction of charged particle trajectories at the Level 2 of the CDF trigger. As the Tevatron luminosity rises, multiple interactions increase the complexity of events and thus the SVT processing time, reducing the amount of data CDF can record. The SVT upgrade aims to increase the SVT processing power to restore at high luminosity the original CDF Data Acquisition capability. In this paper we review the tracking algorithms implemented in the SVT and we report on the first step in the SVT upgrade.
