Description
The Belle II experiment at the KEK laboratory is currently undergoing
commissioning, with first physics data anticipated in 2018.
Understanding the material distribution of detector components is of
critical importance for precision e+e- collider experiments like
Belle-II, as the density and distribution of this material impacts
tracking and vertex reconstruction, as well as other aspects of detector
performance. In the talk I will present a comparison of test beam
experiments using high resolution tracking telescopes to obtain precise
2D images silicon vertex detector modules with the detector model
implemented in the Belle-II simulation. I will also present detailed
studies of material profiles of other components of the Belle II
detector and compare these with the as-built detector
