Cryostats (Cooling Device)
The cryostat for space is the culmination of Sumitomo Heavy Industries' cryotechnology that combines vacuum containers, liquid helium containers, and cryocoolers. The cryostat is only cooled by the cryocooler, which will become the mainstream in the future.
| Item | Specifications |
|---|---|
| Cooling temperature | 1.2K |
| Cooling method | Superfluid helium + 4K cryocooler + 20K Stirling cryocooler |
| Cooling target | X-ray detector + magnetic cryocooler The magnetic cryocooler cools the X-ray detector to 0.05K. This cryostat absorbs the waste heat of the magnetic cryocooler. |
| Service life | Over 3 years |
