Development of the SAFARI Instrument Simulator
Department of Physics & Astronomy, University of Lethbridge, Lethbridge, Alberta, Canada
Three instruments have been proposed for the JAXAESA Space Infrared Telescope for Cosmology and Astrophysics (SPICA) Mission: a mid-infrared coronagraph, a mid-infrared camera and spectrometer, and a far-infrared imaging spectrometer (SAFARI). An overview of the SAFARI instrument simulator currently being developed is presented.
The simulator will not only ﬁnd use during the design phase of the instrument, but also during the evaluation of the performance of the ﬂight model during the ground test campaigns. Through validation of the simulator by using ground test data, it will be possible to predict reliably the in-orbit performance of SAFARI. Speciﬁcally, the simulator will be used to investigate the scientiﬁc capabilities of the instrument at three resolving powers (λ/∆λ = 3, 100, 2000) over the wavelength range 30-210 µm, nominally separated into three sub-bands (Swinyard & Nakagawa, 2008).
