The new Teledyne NIR detectors for the SNAP/JDEM mission spectrograph

Abstract : A new generation of near infrared (NIR) detectors have been developed by Teledyne for the SNAP/JDEM (SuperNova/Acceleration Probe) project. The new detectors are hybridized HgCdTe on a multiplexer with indium bump bonded. Since 2004, Teledyne and the SNAP collaboration have tried to characterize and improve the large format View the MathML source H2RG detectors to meet the SNAP requirements. The results for quantum efficiency and total noise as an integration of a H2RG in a spectrograph demonstrator are presented.
