The EUCLID NISP Detectors System

International audienceThe Euclid mission objective is to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures. The EUCLID project is part of ESA's program Cosmic Vision which is the current cycle of ESA's long-term planning for space science missions. Euclid has been selected by ESA's Science Program Committee for implementation, with launches planned for 2019, on a Soyuz vehicle, from Europe's Spaceport at Kourou, French Guiana. The NISP (Near Infrared Spectro Photometer) is an instrument that will operate in the near-IR spectral region (0.9-2 μm). It will be equipped with a focal-plane based on a mosaic of 16 Teledyne HAWAII2RG 2.4 μm cutoff with their front end readout electronic. A description of this focal plane focusing on the detectors specifications and requirements, their implementation and the expected performances at the end of the Phase A study will be given in this paper
