The Pixel Vertex Detector (PXD) is the inner most tracking detector of the Belle II experiment at the electron positron collider SuperKEKB in Tsukuba, Japan. It was designed to consist out of 40 monolithic Depleted P-channel Field Effect Transistor (DEPFET) modules arranged in two layers around the interaction point.
During 2018 the production of the PXD modules was completed. In a collaborative effort all modules went to a standardized testing procedure for optimization and characterization. As a last mechanical step the modules were glued to ladders. The used procedure turned out to be unsuited for the sensitive detector modules and had to be modified.
Finally, the inner layer was completed and integrated into the inner tracking system together with the Silicon Vertex Detector (SVD). The PXD was commissioned in Japan and cosmic ray measurements were taken before and after the insertion into the Belle II detector.
An overview of the results from the module characterization, from the inspection after module gluing and from the commissioning will be presented.
