Superconducting magnet device for single crystal pulling apparatus |
摘要 |
A superconducting magnet device for a single crystal pulling apparatus is arranged outside a pulling furnace containing a crucible for melting a single crystal material therein so as to apply a magnetic field to the melted single crystal material. The superconducting magnet device for a single crystal pulling apparatus includes a cryostat containing a superconducting coil therein, and a refrigerator port arranged on the outer circumferential surface of the cryostat and provided with a cryogenic refrigerator that cools the superconducting coil. The cryogenic refrigerator is provided in a region of the outer surface region of the cryostat at which the intensity of the magnetic field generated by the superconducting coil is weak. |
