Toward a universal characterization methodology for conversion gain measurement of CMOS APS: application to Euclid and SVOM
On demand | Presented live 18 June 2024 
Abstract
With the expanding integration of infrared instruments in astronomical missions, accurate per-pixel flux estimation for near-infrared hybrid detectors has become critical to the success of these missions. Based on CPPM's involvement in both SVOM/Colibri and Euclid missions, this study introduces universally applicable methods and framework for characterizing IR hybrid detectors and decorrelating their intrinsic properties. The characterization framework, applied to the ALFA detector and Euclid's H2RG, not only validates the proposed methods but also points out subtle behaviors inherent to each detector.

Jean Le Graët has received an education in theoretical physics at Paris Diderot University. Thereafter he has specialized in space instrumentation and obtained a Master of Sciences in "Astronomical and Space-based Systems Engineering ».
Selected first rank for a CNES-CNRS funded PhD grant, he has joined CPPM in Marseille in 2021 as a PhD student to contribute to the preparation of the Euclid mission. As such, his work aims at deriving a ‘pixel’ analysis of Euclid NISP’s H2RG infrared detectors performance response using the on-ground calibration data produced at CPPM through a global approach of the various performance parameters (i.e. noise, linearity, latency, etc.).
