SPICA Mission for Mid- and Far-Infrared Astronomy
Proceedings of SPIE, 2008SPICA (Space Infrared Telescope for Cosmology and Astrophysics) is an astronomical mission optimized for mid- and far-infrared astronomy with a cryogenically cooled 3.5 m telescope. Its high spatial resolution and unprecedented sensitivity in the mid- and far-infrared will enable us to address a number of key problems in present-day astronomy ...

GaAs BIB Photodetector Development for Far-Infrared Astronomy
SPIE Proceedings, 2004GaAs photoconductive detectors offer an extended spectral response in the far-infrared (FIR) compared to presently available stressed Ge photoconductors. Furthermore, responsivity at wavelengths up to 330 microns can be reached without having to apply uniaxial stress close to the breaking limit on each pixel.

Development of GaAs Photoconductors for Far-Infrared/Submillimeter Astronomy
SPIE Proceedings, 2004In today's Astronomy, there is little observational results in the spectral window ranging from far-infrared to submillimeter wavelength. As one of the main reason of this, there is no high performance detector in this spectral region. We started the development of the extrinsic photoconductor for this region utlizing shallow donor levels of gallium ...

New Balloon-Borne Telescope for Far-Infrared Astronomy
SPIE Proceedings, 2000We have developed the new balloon-borne telescope, Far Infrared Balloon-Borne Experiment (FIRBE), to survey the far-infrared radiations of star-forming regions. The primary mirror is an offset parabolid with a diameter of 50 cm (F/2) and telescope structure is made from Carbon Fiber Reinforced Plastics to lighten the whole telescope and hold the strain

SPICA: A 3.5 m Space Infrared Telescope for Mid- and Far-Infrared Astronomy
Advances in Space Research, 2005Abstract The Space Infrared Telescope for Cosmology and Astrophysics (SPICA) mission is a Japanese astronomical infrared satellite project optimized for mid- to far-infrared observations. It will be launched at ambient temperature and cooled down on orbit by mechanical coolers on board with an efficient radiative cooling system, a combination of ...

Lumped Element Kinetic Inductance Detectors for Far-Infrared Astronomy
Proceedings of SPIE, 2008We describe a new type of FIR detector based on lumped element superconducting resonators (LEKIDs). Thesedevices can act as distributed FIR radiation absorbers without the need for an additional coupling structure.In addition, these devices can be integrated into a compact filled array geometry with high filling factor.
