PROBLEM TO BE SOLVED: To extend low temperature holding time of a cryogenic cryostat connected to a cryogenic freezer. SOLUTION: This cryogenic cryostat is provided with a chill supply means to supply chill to the cryogenic cryostat using refrigerant such as liquid helium. In the chill supply means, one end of a stainless steel heat pipe is connected to the cryogenic freezer and a chill generation part of the cryogenic freezer, and the other end is connected to a thermal anchor of the cryostat. By using a heat pipe capable of switching chill carrying effect, chill is transmitted from the cryogenic freezer to the thermal anchor when operation of the cryogenic freezer is on, and chill is not transmitted from the cryogenic freezer to the thermal anchor when operation of the cryogenic freezer is off.
