Abstract
In the apparatus for cooling a superconductor in accordance with the present invention, a male thread portion of an inner container engages a female thread portion of an outer container so as to connect the inner and outer containers to each other. Also, the bottom wall of the inner container is provided with a thermal conductor penetrating therethrough. Further, a sapphire sheet is joined to peripheral portions of an opening of the bottom wall of the outer container facing the thermal conductor, so as to block the opening. As the distance between the bottom wall of the outer container and the bottom wall of the inner container is freely adjusted by changing the engaging position between the thread portions, the gap between a high transition temperature (high T ) superconducting magnetic sensor and the sapphire sheet is adjusted.
