Commissioning and Performance of the LHCb Upstream Tracker

Abstract

The Upstream Tracker is a new, high-precision silicon strip detector installed in the LHCb experiment as part of the overall LHCb Upgrade I project. The detector is an integral part of the tracking system, and plays a crucial role in the reconstruction of charged particles in the new fully software-based trigger. An overview of the Upstream Tracker detector design, its commissioning, and performance are presented.
