DESY develops novel silicon pixel detectors for particle physics. The project Tangerine (Towards Next Generation Silicon Detectors) is dedicated to the development of monolithic active CMOS pixel detectors (MAPS) in a novel 65nm imaging process. This potentially opens up new horizons for the next generation of silicon pixel detector. For the development of groundbreaking detector prototypes in international cooperation with world-leading institutes, DESY is looking for two post-doctoral researchers with a focus on device simulation and test beam integration of pixel detectors.
