Description
The LHCb detector has undergone a major upgrade, enabling the experiment to acquire data with an all software trigger, made possible by front-end readout in real-time and fast and efficient online reconstruction. At the heart of the real-time analysis is a fast and efficient track reconstruction, without spurious tracks composed of segments associated with hits from different charged particles. The Upstream Tracker (UT), a 4-plane silicon microstrip detector in front of the dipole magnet, is crucial to the charged particle trajectory reconstruction. The UT also aids the reconstruction of long-lived particles. The UT was installed in LHCb in early 2023. The first year of commissioning was challenging for data synchronization issues related to the GBTx properties. We report the lessons learned during the early commissioning phase and the upcoming run when the UT performance with beams will be studied.
