The Belle II silicon vertex detector (SVD) is a four-layer double-sided silicon strip detector installed within the Belle II detector located at KEK, Japan. The SVD has been operating smoothly and reliably since the start of data taking in March 2019. The data quality and radiation damage effects have been continuously monitored. In this article, we report the operational experience of SVD, reconstruction performance, and effects of beam background and radiation damage. We also discuss some of the recent efforts to improve the software robustness targeting the high luminosity scenario and hardware activities performed during the first long shutdown of the Belle II experiment.

Abstract
The Belle II silicon vertex detector (SVD) is a four-layer double-sided silicon strip detector installed within the Belle II detector located at KEK, Japan. The SVD has been operating smoothly and reliably since the start of data taking in March 2019. The data quality and radiation damage effects have been continuously monitored. In this article, we report the operational experience of SVD, reconstruction performance, and effects of beam background and radiation damage. We also discuss some of the recent efforts to improve the software robustness targeting the high luminosity scenario and hardware activities performed during the first long shutdown of the Belle II experiment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
