The present invention provides an indirect cooling apparatus and method for a superconducting quantum interference device. The apparatus includes an outer container extending in a vertical direction, an inner container of a metallic material, which is inserted into the interior of the outer container to contain liquid refrigerant and includes an upper plate, a SQUID sensor disposed between the lower surface of the outer container and the lower surface of the inner container Module, a first end connected to the SQUID sensor module directly or indirectly and connected to the lower surface of the inner container, a heat transfer column for cooling the SQUID sensor module, a magnetic shield formed of a superconductor wrapping the upper surface of the SQUID sensor module, And a heat conducting plate thermally contacting the other end of the heat transfer column and stacked on the upper surface of the magnetic shield. The inner container has a space separated from the outer container, and the space between the inner container and the outer container is in a vacuum state. |
