Claims

[Scope of utility model registration request]

A measuring element is disposed in a cryogenic part maintained at a cryogenic temperature, a room temperature vacuum container is provided in which the cryogenic part is housed with vacuum insulation, and an intermediate temperature is provided between the cryogenic part and the vacuum container. A pre-cooled intermediate temperature section is provided, a rod-shaped structure connects the extremely low temperature section and the vacuum container, and the vacuum is passed from the measurement element through a thermal anchor fixed to the intermediate temperature section to connect the vacuum container. In a cryogenic apparatus in which a measurement line is led to an external room temperature part and the cryogenic part is measured in the room temperature part, at least a One of the measurement lines is connected to the structure, and the temperature TM of the measurement line and the temperature T of the structure at the contact part.
1. A cryogenic device characterized in that the wiring is wound around C in a position such that the relationship between TM and TC is such that TM>TC.
