Belle II pixel detector: Performance of final DEPFET modules

Abstract A DEpleted P-channel Field Effect Transistor(DEPFET) based pixel detector was developed for the Belle II VerteX Detector (VXD). It is designed to achieve a good impact parameterresolution better than 15 μm at the very high luminosity conditions of this experiment. In the first half of 2018 four final productionmodules have been deployed in the commissioning run of the detector and their performance is discussed.
