• 論文の詳細を見る

• The HII/L2 mission (SPICA) is a future mission to launch a large infrared observatoryto the L2 orbit by an H-IIA rocket. A unique feature of its cryogenic system is a `warm launch"system using radiative cooling and mechanical cooling in orbit to cool down its detectors andmirrors to 4.5K. By adopting this system, we can remove the heavy vacuum shell and the heliumtank needed for traditional cryostats, and reduce the weight of the spacecraft dramatically.
