Engineering technology to design and construct a cooling system
using a cryocooler to create the cryogenic environment (below
-150℃) required by the cooling target
Cooling system divided into the cryogenic fluid cooling system using
cryogenic fluid (liquid nitrogen, liquid helium, etc.) and the cryogenic
conduction cooling system using a solid structure with good thermal
conductivity.
