Abstract

SPICA is the next generation infrared telescope. It requires the telescope temperature less than 8 kelvins. The conceptual design adopts v-groove structure like Planck, the telescope shield cooled acitively by the 2 stage stirling mechanical coolers, and the j-t coolers to cool the telescope. Another 1k j-t cooleres cools the mission instruments. The conceptual design as well as the development and the verification plan will be presented.
