Monitoring alignment performance for LHCb's Scintillating Fibre Tracker — Nils Breer and •Sophie Hollitt — Experimentelle Physik 5, TU Dortmund

During the LHC upgrade period, the LHCb experiment has replaced the majority of its subdetectors and extensively upgraded its trigger system. Before the physics data collection period late in 2022, careful commissioning of the full system is required. The Scintillating Fibre Tracker (SciFi) is the first detector after the LHCb magnet, and its alignment will be crucial for the final mass and momentum resolution of the upgraded experiment.

In this talk, we discuss how misalignment effects in the SciFi detector can be monitored via tracking and physics performance, and give an overview of the alignment and calibration procedures for the commissioning period of the detector.
