The operational experience and performance of the ATLAS SCT during LHC Run-3 operations — •Alessandro Guida — Humboldt University, Berlin, Germany

The ATLAS SemiConductor Tracker (SCT) restarted operations in LHC Run-3. The SCT successfully operated in LHC Run-2 (2015-2018) which came with high instantaneous luminosity and pileup conditions that were far in excess of what the SCT was originally designed to meet. Similar conditions are now faced during the on-going Run-3 and first significant effects of radiation damage in the SCT are observed.

This talk will summarise the operational experience, challenges and performance of the SCT during the first years of Run-3 operations. The observation and prospect of radiation damage on SCT silicon strip sensors will also be presented.
