ABSTRACT:
A cooling apparatus comprises a pulse tube refrigerator (A) having a pressure source (1), a cold reservoir (6), a condenser (7), a pulse tube (9), a radiator (10), and a phase adjuster (12); and a low-temperature container having a liquid reservoir (21) fixed to a vacuum tank (31) through heat-insulating support members (36) and (37). The condenser (7) is fixed to a cold end (6b) of the cold reservoir (6), and is disposed in a gas phase portion (21a) of the liquid reservoir (21). A hot end of the pulse tube (9) is fixed to the vacuum tank (31) and is disposed in such a manner that a cold end (9b) of the pulse tube (9) is located lower than the hot end and is located in a liquid phase portion (21b) of the liquid reservoir (21). The cold end (9b) of the pulse tube (9) is disposed outside the liquid reservoir (21) but within the vacuum tank (31), and the cold end (9b) of the pulse tube (9) and the condenser (7) communicate with each other through piping (8).
