Development of the clustering algorithm for the LHCb Upgrade II SciFi tracker — •Jan Sorokovski, Michael Lupberger, and Marco Gersabeck — Albert-Ludwigs-Universität Freiburg, Freiburg im Breisgau, Germany

The LHCb Upgrade II aims to increase the instantaneous luminosity by a factor of 5. To achieve that, many detector systems have to be upgraded to address the increased detector occupancy and pileup. This includes the new downstream tracker, the Mighty Tracker, which will combine silicon pixel sensors in the high-occupancy region and improved Scintillating Fibres (SciFi) in the remaining region.

One of the key challenges of the SciFi Tracker is the handling of the output of the advanced front-end chip. For that, the development of an efficient, real-time clustering algorithm capable of processing the increased data volume, while maintaining a high spatial resolution and track hit efficiency, is crucial. A major consideration are noise sources, which have to be identified, understood and characterised to provide robustness against noise and to improve overall performance.

In this presentation, an early algorithm design and noise considerations and studies are
