Optimization procedure of the PXD modules for Phase 3 — •Markus Reif für die Belle 2 Kollaboration — Max Planck Institute for Physics

The Pixel Vertex Detector (PXD) is part of the new Belle II detector at the electron positron collider SuperKEKB in Tsukuba, Japan. For Phase 3, 20 modules were installed, arranged cylindrically around the interaction point. Each module contains 192000 Depleted P-channel Field-Effect Transistor (DEPFET) pixels.

Phase 3 starts in the beginning of 2019. For this phase the ’full’ Belle II detector containing all subdetectors will be installed as well as the complete SuperKEKB collider. This then allows for the first time to take data with the full system.

To optimize the PXD modules for data taking, several tests are performed. The software framework had to be adapted from the lab setups, where only single modules were operated, to the final detector setup in Japan.

The tests which are performed and the results from the currently installed PXD modules are presented.
