NISP Detector team, CPPM group
The characterization team’s expertise is based on an early experience with IR detectors in the framework of the SNAP collaboration and expanded to the highest level within the Euclid project. The team members combine strong complementary skills: mechanical and thermal design of the bench, software development for acquisition and bench control & automation, instrumentation, test procedures of pixel detectors. Thanks to the close collaboration of CPPM & IPNL, the team has developed and validated dedicated test facilities of high quality and excellent running efficiency with a fully automated acquisition scheme. The characterization of the 20 IR detectors has taken over one year with 85% efficiency, leading to 400 TB of data from which the team will derive pixel map products and models for the SGS. The emphasis during these tests was the collection of data to enable the control of relative pixel gains, non-linearities, and persistence.
