る等の問題点、欠点があった。Both cooling type superconducting magnet devices mainly consist of a superconducting film and a coil container for housing it and supporting the generated electromagnetic force. The forced cooling type has the advantage of having a mechanically strong structure that can take a current density of IB:Bj (IB:Bj). It was necessary to cool the coil container with the refrigerant flowing through the flow path.The heavy structure of the coil container accompanying the increase in the size of superconducting Madai-T equipment in recent years has resulted in a significant increase in the time required to cool the superconducting coil. For this reason, methods have been considered to cool the coil container by installing a separate cooling system, such as by installing a snake 9n on the surface of the coil container, but the cooling product is limited. As a result, a large amount of time is required for cooling.Furthermore, when the cooling system is composed of coiled pipes, there are problems and drawbacks such as the flow rate of the refrigerant being restricted due to pressure loss in the pipes.
