Data pubblicazione: | 2016 | Titolo del volume in cui è pubblicato il poster: | Space Telescopes and Instrumentation 2016: Optical, Infrared, and Millimeter Wave | Curatore/i del volume in cui è pubblicato il contributo: | MacEwen, Howard A.; Fazio, Giovanni G.; Lystrup, Makenzie | Serie: | PROCEEDINGS OF SPIE | Numero: | 9904 | Da pagina:: | 99040T-1 | Abstract: | 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). | Titolo del convegno: | Space Telescopes and Instrumentation 2016: Optical, Infrared, and Millimeter Wave | Luogo del convegno: | Edinburgh, UK | Periodo del convegno: | 26 June - 1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/30513 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9904/1/Euclid-Near-Infrared-Spectrometer-and-Photometer-instrument-concept-and-first/10.1117/12.2232941.full?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510601871 | DOI: | 10.1117/12.2232941 | Bibcode ADS: | 2016SPIE.9904E..0TM | Fulltext: | open |
