PROBLEM TO BE SOLVED: To improve the strength against a shear stress in a support member.SOLUTION: A superconducting electromagnet 10 comprises: a vacuum container 11 a superconducting coil 13 arranged in the vacuum container 11 a support member 15 arranged in the vacuum container 11 and that supports the superconducting coil 13 and at least one of a joint member 20 contacted with the support member 15 and that connects the support member 15 with the vacuum container 11, and a joint member 23 contacted with the support member 15 and that connects the support member 15 with the superconducting coil 13. A thickness T2 at a contact part 21 and/or a thickness T3 at a contact part 24 are smaller than a thickness T1 of the support member 15.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】 支持部材におけるせん断応力に対する強度を向上させる。【解決手段】 超伝導電磁石10は、真空容器11と、真空容器11の内部に配置された超伝導コイル13と、真空容器11の内部に配置され、超伝導コイル13を支持する支持部材15と、支持部材15と接触し、真空容器11に対して支持部材15を接続する継手部材20、及び、支持部材15と接触し、超伝導コイル13に対して支持部材15を接続する継手部材23の少なくとも一方と、を備え、接触部21における厚さT2、及び/又は、接触部24における厚さT3は、支持部材15の厚さT1よりも小さい。【選択図】図3
