Characterization of Euclid-like H2RG IR detectors for the NISP instrument

Abstract : The success of the Euclid’s NISP (Near-Infrared Spectro-Photometer) survey requires very high performance 2.3 µm cutoff H2RG detectors for which tight specifications have been defined. These must be verified over more than 95% of the focal plane through a thorough characterization. CPPM is in charge of this critical and challenging step and has therefore developed dedicated facilities, analysis tools and methods. First tests of high performance engineering grade detectors show the quality of our full characterization chain and will be presented, including dark current, total noise, both CDS and science modes (spectroscopic and photometric), conversion gain and persistence.
