【 摘 要 】

The Space Infrared Telescope for Cosmology and Astrophysics (SPICA) is an astronomical mission optimized for mid- and far-infrared astronomy, envisioned for launch in the 2020s. The Mid-infrared Camera and Spectrometer (MCS) is a model instrument that covers the 5–38μm wavelength range and enables imaging and spectroscopic observations via four modules named WFC-S, WFC-L, HRS, and MRS. Both of the wide field camera (WFC) modules have a 5-arcmin square field of view (FOV) but cover different wavelength ranges; WFC for the short wavelength region (WFC-S) covers 5 to 24μm, whereas WFC for the long wavelength region (WFC-L) covers 18 to 38μm. The High Resolution Spectrometer (HRS) covers the 12–18μm range with a resolving power of 22,000–30,000, and the Mid Resolution Spectrometer (MRS) performs integral filed units spectroscopy with a 12′′ by 8′′ FOV. MRS simultaneously covers the 12–38μm range with a moderate resolving power of 720–2000. Here, we report sensitivity estimates from a detailed modeling process...
