Abstract
An apparatus for mounting a superconducting element includes a first chamber which accommodates a first coolant and maintains the superconducting element at a very low temperature, a second chamber which accommodates a second coolant and is thermally connected to the first chamber via a barrier member, the second coolant being liquidized at a temperature lower than that of the first coolant, and a cooling device which is connected to the second chamber and liquidizes the first coolant.
