Abstract
Abstract
The Silicon Vertex Detector of Belle II is a
state-of-the-art tracking and vertexing system based on double-sided
silicon strip sensors, designed and fabricated by a large
international collaboration in the period 2012–2018. Since 2019 it
has been in operation providing high quality data with a small
number of defective channels (<1%), a large hit-finding
efficiency (>99%), a good signal-to-noise ratio (well in excess
of 10 for all sensor configurations and tracks). Together with the
good control over the alignment, these are all essential factors to
achieve good tracking reconstruction and physics performance. In
this extended paper we try to document all the aspects of the SVD
challenges and achievements, in the spirit of providing information
to the broader community and help the development of high quality
detector systems, which are essential tools to carry out physics
research.
