Abstract
PURPOSE:To keep an evaporation quantity of a cooling medium with little latent heat such as liquid helium or the like at an extremely low value and to execute an accurate measuring operation by a method wherein an oxide superconducting conductor is connected to a measuring element set at an extremely low temperature and a wire of copper, Al or an alloy of these is connected to a region whose temperature is higher than a critical temperature of the oxide superconducting conductor. CONSTITUTION:Terminals of a measuring element 2 installed in an extremely low temperature region 1 are connected to oxide superconducting conductors 3. Wires of copper or Al or an alloy of these are connected to the oxide superconducting conductors 3 in a temperature region 4 of a cooling medium whose critical temperature is lower than that of the oxide superconducting conductors 3, whose latent heat is large, whose cost is low and which is not dangerous and in another region whose temperature is higher than that temperature. If the oxide superconducting conductors 3 are composed of a Y-Ba-Cu-O-based material, the temperature region 4 of the cooling medium can be set at a temperature of liquid nitrogen. By this setup, because the oxide superconducting conductors 3 display a superconducting state at a temperature of lower than their critical temperature, a large electric current which is lower than a critical current value can be supplied to the measuring element without generating the heat.
