<P>PROBLEM TO BE SOLVED: To provide a superconducting magnet device in which the strength of a radiation shield having slits is improved. <P>SOLUTION: A superconducting magnet unit 2 comprises a superconducting coil 3, a radiation shield 6 which is disposed so as to surround the superconducting coil 3 and in which one or more slits 62 are formed, and a vacuum container 7 which includes the superconducting coil 3 and the radiation shield 6. The radiation shield 6 is fixed by fitting a spacer 63 which is formed from the same material as that of the radiation shield 6, into the slits 62 via an insulating layer 64. <P>COPYRIGHT: (C)2013,JPO&INPIT |
