ABSTRACT:
There is provided a cooling chamber which communicates with a nozzle pipe. A heat absorption portion is formed on an outer peripheral surface of an expansion chamber of a cryopump and the heat absorption portion is disposed inside the cooling chamber. For example, ordinary temperature nitrogen gas is supplied to the cooling chamber as a cooling medium, the heat of the nitrogen gas is absorbed by the heat absorption portion of the cryopump, and then the nitrogen gas is jetted from a tip end opening of the inner pipe. With such an arrangement, it is possible to easily cool an object to be cooled such as a sample using a cooling medium which costs less than liquid nitrogen. Further, the nozzle pipe has a triple-structured arrangement comprising an inner pipe, a vacuum adiabatic pipe and an outer pipe, wherein the vacuum adiabatic pipe has a tapered surface at a tip end periphery thereof in which a diameter of the vacuum adiabatic pipe is gradually reduced toward the tip end of the inner pipe, thereby preventing the current of the drying medium from being turbulent at the tip opening of the inner pipe 11 and also preventing fresh air including humidity from turning around and directing toward the inner pipe 11. As a result, frost is prevented from adhering to the tip end of the inner pipe, thereby facilitating stabilization of cooling performance.
