000002026 520__ $$aThe Belle II experiment at the Super Flavour Factory SuperKEKB in Tsukuba, Japan, has started regular operation with its final detector setup in spring 2019. The Belle II vertexing system consists of four layers of double sided silicon strips (SVD) and two layers of DEPFET pixel sensors (PXD). These inner most pixel layers are arranged at radii of 14 mm and 22 mm around the beam pipe. The sensors with pixel sizes down to 50 μm × 55 μm are thinned down to 75 μm thickness to minimize multiple scattering. They are most crucial for reconstructing the secondary decay vertices of short lived B and D mesons with a precision of better than 15 microns. The high luminosity and harsh background conditions impose challenges on the operation of the detector close to the interaction point.
