PROBLEM TO BE SOLVED: To provide a superconducting magnetic apparatus capable of reducing entry of heat without enlarging the superconducting magnetic apparatus, and having a simple structure.SOLUTION: The superconducting magnetic apparatus includes a refrigerant tank for storing an ultra-low temperature cooling medium which cools a superconducting coil a heat shield which surrounds the refrigerant tank a vacuum tank 5 which surrounds the heat shield a refrigerator 10 for reliquefying the ultra-low temperature cooling medium through the refrigerant tank while being attached to the vacuum tank 5 and a piping having one edge communicatable with the refrigerant tank and other edge communicatable with outside of the vacuum tank 5. In the hollow cylindrical superconducting magnetic apparatus 1, a center axis passing through magnetic field is horizontally arranged. The refrigerator 10 and piping are collectively arranged at a slope C biased to one side of circumferential direction at the upper peripheral surface of the vacuum tank 5 from a central part of circumferential direction.COPYRIGHT: (C)2009,JPO&INPIT【課題】大型化を招くことなく、また、構造の簡素化を図るとともに、熱侵入を低減する。【解決手段】超電導コイルを冷却する極低温冷媒を貯液する冷媒槽と、冷媒槽を包囲する熱シールドと、熱シールドを包囲する真空槽5と、真空槽5に取り付けられ、冷媒槽に通じて極低温冷媒を再液化するための冷凍機10と、一端部が冷媒槽に連通し、他端部が真空槽5の外側に連通可能な配管と、を備え、磁場空間を通る中心軸が水平方向に配置された中空円筒状の超電導マグネット装置1であって、真空槽5の上側周面における周方向の中央部位から周方向の一方側に偏倚した傾斜部位Cに、冷凍機10および配管をまとめて配置したことを特徴とする。【選択図】図1
