21 September 2012Detector systems for the mid-infrared camera and spectrometer on board SPICA
Mid-infrared Camera and Spectrometer (MCS) is one of focal plane instruments for SPICA (Space Infrared
Telescope for Cosmology and Astrophysics), which have 3 m class 6 K cooled telescope. MCS will provide wide
field imaging and low-, medium-, and high-resolution spectroscopic observing capabilities with 7 detectors in the
wavelength range from 5 to 38 micron. Large format array detectors are required in order to realize wide field of
view in imaging and wide spectral coverage in spectroscopy. We are planning to cover the wavelength range of
5-26 micron by Si:As IBC 2K x 2K and 20-38 micron by Si:Sb BIB 1K x 1K. The development status and their
design including the electrical and thermal design are described.
