Enhanced Silicon Sensor Capabilities at Teledyne e2v

摘要

Teledyne e2v continues to develop silicon sensors for ground and space-based Astronomy applications. Multiple new BSI CMOS sensors are presented, which use a patented back-bias structure to achieve NIR and soft x-ray quantum efficiency comparable to a deep depletion CCD. These include NIR-enhanced variants of Capella space imager and a predevelopment for THESEUS in collaboration with the OU with large x-ray sensitive pixels. Two new extremely large BSI CMOS sensors, the first in a buttable format suitable for focal plane arrays also incorporating the back-bias structure and the second a high speed, ultra-low noise sensor for use in the Teledyne Princeton Instruments COSMOS camera. A range of BSI CCD developments are presented. These include development work towards a curved CCD231-84, the HiRho CCDs used in the huge 3.2 Gigapixel Vera Rubin focal plane array and the Space telescope projects: Euclid, Plato and WSO-UV.
