Abstract:
1. A conduction cooling superconducting magnet device, comprising: a vacuum chamber; a superconducting coil accommodated in said vacuum chamber; a radiation shield arranged in said vacuum chamber with a prescribed space from said vacuum chamber to surround a periphery of said superconducting coil; a refrigerator for cooling said superconducting coil and said radiation shield by conduction; a provided member at least partly lying between said vacuum chamber and said radiation shield, through which heat is conducted from said vacuum chamber to said radiation shield; and a cooling pipe having opposite end portions drawn out of said vacuum chamber and an intermediate portion in contact with said superconducting coil, said radiation shield, and said provided member, said provided member dissipating heat into a coolant flowing through said cooling pipe, to reduce the heat conducted to said radiation shield.
