Test du module Cassegrain de l’instrument SPIRou
Testing of the SPIRou (InfraRed SpectroPolarimeter) instrument’s Cassegrain module, in a climatic chamber. This enables simulation of the climatic conditions that the module will experience when it is installed in the dome of the Canada-France-Hawaii Telescope (CFHT). SPIRou (InfraRed SpectroPolarimeter) consists of a near-infrared spectropolarimeter combined with a high-precision velocimeter. Installed at the Cassegrain focus of the CFHT at the end of 2017, SPIRou was designed to detect habitable Earth-twin exoplanets in the planetary systems of red dwarf stars in the vicinity of the Sun. It could also unravel the mysteries of the birth of stars and planets, by observing for the first time the magnetic fields of protostars aged just a few hundred thousand years.
