| 摘要 |
The present invention is provided with: a step (S100) in which a front end part of a cooling machine is brought into contact with a contact part (182) of a heat-transfer member (180), thereby thermally connecting the cooling machine and a superconducting coil (110) through the heat-transfer member (180) and cooling the superconducting coil (110) to an extremely low temperature; a step (S110) in which, following the cooling step (S100), the front end part of the cooling machine is separated from the contact part (182) of the heat-transfer member (180); and a step (S120) in which, following the above-described separating step (S110), liquid helium (130) is injected into a helium tank (120). |
