Abstract

The silicon vertex detector (SVD) for the Belle II experiment at the SuperKEKB accelerator in Japan is responsible for detecting particle’s origins. It comprises four cylindrical layers with ladder-like double-sided silicon detector (DSSD) arrays on each layer. The ladders produced under a stringent quality control showed good mechanical tolerance with a DSSD distortion <300 µm and with an electrical efficiency >99%. The SVD was commissioned with cosmic-ray events for two months. Cluster-finding efficiency was estimated in the commissioning to be >98.5%. The commissioned SVD had been installed on the Belle II detector. The so-called "phase 3" of the experiment with the SVD will start in March 2019.
