Title:
SUPERCONDUCTING ELECTROMAGNET DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/239650
Kind Code:
A1
Abstract:
Provided are novel cooling system for a superconducting electromagnet, and a superconducting electromagnet device in which the cooling system is used. The superconducting electromagnet device according to the present invention comprises a vacuum container, a radiation shield contained within the vacuum container, a plurality of superconducting coils contained within the radiation shield, and a coil container that accommodates the superconducting coils, wherein the superconducting electromagnet device is characterized by comprising a cooling system for superconducting coils, the cooling system including the coil container, a refrigerant container in which a refrigerant accumulates, refrigerant piping through which the coil container and the refrigerant container communicate, a trap member to which the refrigerant is supplied from the refrigerant piping, and a refrigerator provided to the refrigerant container, and the trap member being provided between the inner wall of the coil container and the surface of the superconducting coils. The superconducting electromagnet device is further characterized in that the trap member is a transcalent body having a gap through which the refrigerant can penetrate.
