The LHCb Upstream Tracker: operations and performance in Run3

The Upstream Tracker is a critical component of the tracking system in the LHCb Upgrade I detector. It has been commissioned and is now operational, collecting data during Run 3. The tracker enhances the reconstruction of charged particle tracks and long-lived particles, such as $\Lambda$ and $K^{0}_{s}$, thereby improving the performance of the software trigger. This presentation will cover experiences with detector operations and data acquisition, along with the performance results based on Run 3 data.
