Real-time alignment and calibration for Run 3 at the LHCb experiment — •Biljana Mitreska and Johannes Albrecht — TU Dortmund University, Dortmund, Germany

The real-time alignment and calibration procedure is a fully automatic procedure at LHCb that is executed at the beginning of each fill of the LHC. The alignment estimates the position of detector elements and the correct alignment contributes to improving the data for offline analysis. Its importance in Run 3 is even more enhanced due to having a fully software trigger at LHCb. The procedure is implemented for the full tracking system at LHCb with the event reconstruction run as a multithreaded process. The operational and technical point of view of this procedure during the Run 3 data-taking is discussed with the focus on performance and optimisations done regarding the new computing framework and the new detectors.
