Descripción
The Euclid mission objective is to understand why the expansion of the
Universe is accelerating through by mapping the geometry of the dark
Universe by investigating the distance-redshift relationship and tracing
the evolution of cosmic structures. The Euclid project is part of ESA's
Cosmic Vision program with its launch planned for 2020 (ref [1]). The
NISP (Near Infrared Spectrometer and Photometer) is one of the two
Euclid instruments and is operating in the near-IR spectral region (900-
2000nm) as a photometer and spectrometer. The instrument is composed of:
- a cold (135K) optomechanical subsystem consisting of a Silicon carbide
structure, an optical assembly (corrector and camera lens), a filter
wheel mechanism, a grism wheel mechanism, a calibration unit and a
thermal control system - a detection subsystem based on a mosaic of 16
HAWAII2RG cooled to 95K with their front-end readout electronic cooled
to 140K, integrated on a mechanical focal plane structure made with
molybdenum and aluminum. The detection subsystem is mounted on the
optomechanical subsystem structure - a warm electronic subsystem (280K)
composed of a data processing / detector control unit and of an
instrument control unit that interfaces with the spacecraft via a 1553
bus for command and control and via Spacewire links for science data
This presentation describes the architecture of the instrument at the
end of the phase C (Detailed Design Review), the expected performance,
the technological key challenges and preliminary test results obtained
for different NISP subsystem breadboards and for the NISP Structural and
Thermal model (STM).
