The BELLE 2 particle collision experiment in Japan started taking data in spring 2019. A european collaboration led by Germany developed the pixel detector (PXD) for particle tracking and vertex determination in the experiment. The sensors of the PXD are based on DEpleted P-channel Field Effect Transistors (DEPFETs). The SiLab group has been involved for 10 years in the investigation of this technology and the development and testing of the final components.
