DESY: Package for CMOS sensor array for the UV camera (Project ULTRASAT)

DESY is one of the world's leading accelerator centres. Researchers use the large-scale facilities at DESY to explore the microcosm in all its variety. Zeuthen is (besides Hamburg) the second location of DESY, located in the south-eastern outskirts of Berlin. Since 2011, the DESY Zeuthen campus has been profiled as a globally visible center for astroparticle physics. DESY Zeuthen is involved in several international research projects in astroparticle physics. Ultrasat is an astronomical satellite mission whose wide-angle telescope will perform a deep time-resolved all-sky survey in the near-ultraviolet (NUV). The satellite shall be in orbit in 2024 and will then take data for at least 3 years. The main science objectives of Ultrasat are the detection of counterparts to gravitational wave sources and of supernovae. DESY joined the Ultrasat mission in 2019 and will provide the Focal Plane Array (FPA or ‘camera’). The core of the camera will be a back side-illuminated (BSI) CMOS sensor array, consisting of four sensors. These sensors will be assembled on a package. The sensor package shall be designed, produced and assembled by an external company and is subject of this tender.
