Characterizatoin of DEPFET Pixel Modules for PXD2 — •Larissa von Jasienicki, Jannes Schmitz, Patrick Ahlburg, Georgios Giakoustidis, Botho Paschen, Florian Bernlochner, and Jochen Dingfelder for the Belle II collaboration — University of Bonn, Germany

The SuperKEKB electron-positron collider in Japan has reached unprecedented luminosities. The Belle II experiment operating at the SuperKEKB collider is equipped with a PiXel Detector (PXD) based on the Depleted P-channel Field Effect Transistor (DEPFET) technology, which serves as the innermost two layers of the VerteX Detector (VXD) of Belle II and was designed to cope with the large particle rates. The current PXD is, however, incomplete, since (mostly) only the innermost of the two layers is installed. A new full-scale PXD (*PXD2*) is currently being built and is expected to be installed in 2023(?).

This talk highlights improvements in the lab characterization of individual PXD2 modules. In particular, the biasing requirements of the sensors and investigations of the intrinsic properties like transconductance and gain of the DEPFET sensor will be discussed.
