This paper describes the general considerations for the design of the cryogenic systemfor HII/L2 Mission (SPICA) operated at the baseline temperature of 4.5K and at the lowesttemperature of 1.7K during the cold mission life of 5 years or longer. The characteristic feature ofthe system design lies in the He II-free cryogenic system to allow the elimination of a bulky vacuum-tight outer shell, which, in turn, makes it possible to give sufficient room for a large telescope mirrorand a longer cold mission life. The cryogenic cooling capability relies on closed-cycle mechanicalcryocoolers and radiator. A possible cryogenic design that fulfills the cryogenic requirement for themission is presented here. In addition, the present status of available space cryogenic technology isreviewed and the required technical development plan is also discussed for the design considerationincluding the overview design and cryogenic components. |
